A major concern in exporting agricultural commodities is the introduction or spread of exotic quarantine pests to the new area. To prevent spread of insect pests, various phytosanitary measures are used. In this study, we compared the effect of electron beam and X-ray irradiation on development and reproduction of the two-spotted spider mite, Tetranychus urticae. Eggs, nymphs, and adults were irradiated at target doses of 50, 70, 100, 150, 200, 250, and 300 Gy with electron beam and 10, 20, 30, 50, 70, 100, 150, and 200 with X-ray irradiation. When eggs were irradiated, egg hatching was completely inhibited at 150 Gy of electron beam and 50 Gy of X-ray irradiation. When irradiated to the nymphs, emergence was not affected at all target dose in both electron beam and X-ray irradiation. Hatchability of F1 generation was significantly decreased at 100 Gy of electron beam and 70 Gy of X-ray irradiation. When irradiated to the adults, longevity did not show any differences at all target dose in both electron beam and X-ray irradiation. These results suggest that the effect of X-ray irradiation was more potential than electron beam irradiation.

The effect of electron beam irradiation on development and reproduction of imidacloprid-resistant (R strain) and -susceptible (S strain) Aphis gossypii were compared. Nymphs and adults of R and S strain were irradiated at target doses of 50, 100, 150, and 200 Gy. When nymphs were irradiated, emergence was not affected at all target dose, but number of F1 nymph was perfectly inhibited at 150 Gy in both strains. When irradiated to the adults, longevity slightly decrease at 150 Gy and above. Fecundity was strongly decreased at 100 Gy, but was not completely inhibited even at 200 Gy. Emergence of F1 nymph was decreased at 100 Gy and completely inhibited at 200 Gy. However, there were no significant differences on development and reproduction of R and S strain. We also conducted the comet assay immediately after irradiation and over the following 10 day period. Severe DNA fragmentation in A. gossypii cells was observed just after irradiation and the damage was repaired during the post-irradiation period in a time-dependent manner. These results suggest that electron beam irradiation induced abnormal development, reproduction, and DNA damage in A. gossypii, but there were no significant differences between R and S strain.

This study was examined for activity of aggregation pheromone trap with residual effect of insecticides against Riptortus pedestris. Time of escape was from aggregation pheromone trap researched 49.74 min (ET99) and 65.01 min (ET99) with 1st and 2nd instar nymph respectively. Six insecticides for the stink bugs were treated to 3 different materials (wood, metal, and plastic). Bifenthrin and fenitrothion were showed 100% insecticidal activity at 48 h to all developmental stage of R. pedestris. Residual effect of bifenthrin and fenitrothion on plastic material were showed 100% insecticidal activity over 15 day after treatment with 1st, 3rd instar nymphs, and adults except 5th instars nymph. In field test using plastic material trap with two pesticides, 1st instar nymphs and adults were showed 100% mortality until 10 day after treatment. These results indicate that R. pedestris might be managed using aggregation pheromone trap with insecticides.

Postharvest insect pest control is highly demanding in agricultural industry including domestic consumer markets and exporting products for a quarantine purpose. Especially, the organic or environmentally friendly agricultural products do not fit to the traditional chemical postharvest treatments using methyl bromide (MeBr) or phosphine (PH3). As an alternative, a physical treatment called CATTS (controlled atmosphere and temperature treatment) has been developed to control various insect and mite pests on ornamental products. The oriental fruit moth, Grapholita molesta, infects the apple or pear fruits and is limited in importing and exporting the infected products. To apply CATTS on this insect pests, the most heat-tolerant stage was determined. Among the immature stages locating on the fruits, the fifth instar larvae were the most tolerant to 44℃ for 20 min. A ramping step of CATTS is to increase chamber temperature from 25℃ to 46℃ under 15% CO2 and less than 1% O2. The ramping rate was positively correlated with the CATTS efficiency. After the ramping step, the duration of CATTS was positively correlated with CATTS efficiency. However, fruit damage by CATTS was negatively correlated with the ramping rate was positively correlated with the CATTS duration. in addition, the CATTS efficiency was highly dependent on the fruit internal temperature at 44℃. From all these parameters, we developed a standard protocol yielding 100% control efficiency of CATTS.

The Japanese termite, Reticulitermes speratus Kolbe, is distributed in Korea widely. Although, termites are not currently a great problem in Korea, it might be increased commercial losses from imported timber. Phosphine (PH3) is very effective fumigant and is widely used to control pests. Oxygen treatment was found to enhance phosphine toxicity and reduce fumigation time against various life stage of insects. In this study, we determined efficacy of oxygenated phosphine fumigation for controlling R. speratus. Fumigation to adults of R. speratus was carried in a desiccator system at 20.9% (normal), 50% and 80% of oxygen concentration for 24 h. Fumigations under higher oxygen levels greatly increased phosphine toxicity to R. speratus. Mortality of termite was increased 15.0% and 16.2% in the 50.0% and 80.0% oxygen concentration with 0.25 mg L-1 phosphine at 5℃, respectively. 100% mortality was determined in 80.0% oxygen concentration with 0.5 mg L-1 phosphine at 5℃. Oxygenated phosphine fumigations have marked potential to improve insecticidal efficacy against R. speratus. These results merit further study as potential fumigant for control of wood destroying pests.

The potato tuber moth, Phthorimaea operculella (Zeller), is considered one of the main causes of potato losses during harvesting and storage. The pest occur throughout the year and its larvae damage the leaves, twigs and tubers. In this study, we have investigated the effects of ethyl formate (EF) and phosphine (PH3) against P. operculella. Fumigation to all stage of P. operculella was carried in a desiccator system at 5℃ and 20℃ for 24 h. As a result, LC99 of PH3 to all stage of P. operculella was showed 1.953 mg L-1 (eggs), 0.100 mg L-1 (larvae), 4.884 mg L-1 (pupae) and 0.240 mg L-1 (adults) at 20℃, respectively. LC99 of EF to all stage of P. operculella was observed 19.808 mg L-1 (eggs), 6.783 mg L-1 (larvae), 141.476 mg L-1 (pupae) and 3.223 mg L-1 (adults), at 20℃ respectively. Larvae and adults showed the highest susceptibility to PH3 and EF at 20℃. LC99 of PH3 to all stage of P. operculella was showed > 1.5 mg L-1 (eggs), 0.187 mg L-1 (larvae), > 1.5 mg L-1 (pupae) and 0.386 mg L-1 (adults) at 5℃ , respectively. LC99 of EF to all stage of P. operculella was showed 27.479 mg L-1 (eggs), 9.580 mg L-1 (larvae), 55.759 mg L-1 (pupae) and 3.084 mg L-1 (adults) at 5℃, respectively. These results indicated that the fumigant efficiency of PH3 and EF is more effective with treated in room temperatures against termites.

An assessment was made of the toxicity of basil, Ocimum basilicum, essential oil, 11 basil oil constituents, seven structurally related compounds and another 22 previously known basil oil constituents and the control efficacy of four experimental spray formulations containing the oil (1, 2, 3 and 4% sprays) to adult American house dust mites, Dermatophagoides farinae. Results were compared with those of two conventional acaricides benzyl benzoate and N,N-diethyl-3- methylbenzamide (deet). The active principles were determined to be citral, α -terpineol and linalool. Citral (24 h LC50, 1.13 μg/cm2) and menthol (1.69 μg/cm2) were the most toxic compounds, followed by methyl eugenol (5.78 μg/cm2). The toxicity of these compounds was more toxic than that of benzylbenzoate(LC50, 8.41 μg/cm2) and deet (37.67 μg/cm2). These compounds were consistently more toxic in closed versus open containers, indicating that their mode of delivery was largely a result of vapour action. Basil applied as 3 and 4% experimental sprays provided 97 and 100% mortality against the mites respectively, whereas permethrin (cis:trans, 25:75) 2.5 g/l spray treatment resulted in 17% mortality. Reasonable mite control in indoor environments can be achieved by spray formulations containing the basil oil (3 and 4% sprays) as potential contact-action fumigants.

Brown planthopper, Nilaparvata lugens is giving enormous damage to rice production. In this work, virulence of four Beauveria bassiana isolates against brown planthoppers was investigated by applying fungal granules on the water of pots, and we further examined the growth of hypha on the rice plants from the water surcae to explain the insecticidal mode of action. We used Beauveria bassiana (Bb) ERL 836, 1170, 1575 and 1578 isolates, which produced ~2×108 conidia/g of millet grain in a solid culture. Rice seeding was grown in breeding boxes at 28±2℃ for 5 days. Mycotized millet grains were treated on the water in a box at 1 g/box and the rice seeding was infested with 18~25 brown planthopper adults per box. A chemical pesticide and water treatment served as controls. Among the treatments, Bb ERL 836-treated plants had the lowest damage, rather than the other fungal treatments in laboratory assays. Hyphal growth on the stem of rice plants was observed in Petridish conditions under a fluorescent microscopy. This work suggests a possible control of brown planthoppers using entomopathogenic fungi.

Entomopathogenic fungi formulated as wettable powders and suspension concentrates have been sprayed to crop pests for pest management. However, the use of fungal granules to control paddy field pests has not been fully explored. Herein, several Beauveria bassiana isolates (ERL 1170, 1578 and 836) were produced as granules using a millet-based solid culture. The granules were applied to the rice nursery 3 days before transplanting and their control efficacy against rice water weevils was determined in paddy fields. The solid cultures produced ~1×108conidiag-1ofmilletgrains10daysaftertheinoculation. The granules were applied to the soil in the rice nursery 3 days before the rice seedlings were transplanted in the paddy fields. Rice in plots with granules of ERL1578 had 17.3% leaf damage (74% control efficacy) 14 days post application, whereas rice plants in the non-treated control had 66.5% damage. Rice plants treated in the nursery with ERL1170 and ERL836 had 52~54% damage. In the rice plots previously treated with ERL1578 the smallest numbers of larvae and adults were observed 38 days post application. In laboratory conditions, ERL1578-treated larvae were tuned pink and covered with mycelial mass. Applications of millet-based B. bassiana granules on rice nursery soil can be an effective and efficient biological control strategy for the management of rice water weevils. This method is relatively inexpensive and requires less labor compared to practices involving the spraying of fungi directly on rice in paddy fields.

F. occidentalis causes to decrease the yield of chrysanthemum flower economically because it is the major crop pest injuring the flower directly at flowering period in chrysanthemum artificial houses. The control of it with chemicals is very difficult because the resistance of it to chemicals is so high. F. occidentalis began to occur at early-May and increased rapidly mid-May after in standard chrysanthemum artificial houses, Yesan, Chungcheongnam-do. In case of a farm, the density of it increased continuously in spite of chemical control . The times of chemical control to depress the density of it was 6 or 7th for cultivation period of chrysanthemum. We put the flowering yellow pot-mum already (trap plant attracting F. occidentalis) in standard chrysanthemum PVC-houses and set the yellow sticky cards up at an interval of 5m from trap plant(TP). The more yellow sticky trap near to trap plant, the more F. occidentalis was attracted to yellow sticky trap. TP was more attractive to adult F. occidentalis up to distances of 10m. The numbers of it attracted to yellow sticky traps at different distance from TP was not different significantly when standard chrysanthemum bloomed. We put the TP in standard chrysanthumum PVC-house at an distance of 20m and released the natural enemies (Orius laevigatus) on TP at 3 times, an interval of 7 days. And then we set yellow sticky traps up at an distance of 5m from TP and compared the plot with TP+natural enemy(NE) to the plot without them. The density of F. occidentalis was rather lower at TP+NE plot than the plot without at the formative period of flower bud of standard chrysanthemum. Therefore, The yellow flowering chrysanthemum possesses great value of TP attracting F. occidentalis in chrysanthumum PVC-house up to flowering period of cultivating chrysanthemum, and if it is used with natural enemy and chemicals simultaneously, farmers can minimize the quantity of chemicals used.

일본의 야간조명을 이용한 야행성 해충 방제 연구는 이미 실용화되어 보급되고 있다. 특히, 황색 형광등을 이용한 밤나방 방제 기술은 여러 작물에 적용되고 있다. 하지만 단일식물인 가을 국화는 밤나방 방제를 위해 야간조사하면 화아분화에 영 향을 미쳐 개화가 지연된다.
본 연구에서는 황색 LED를 이용하여 가을 국화의 개화지연 없이 국화의 꽃봉오 리를 식해하는 왕담배나방 Helicoverpa armigera (Hübner)을 방제하기 위한 황색 LED의 효과적인 점멸조건을 검토하였다.
적외선 센서를 이용한 actograph 상부에 20 mW/m2의 571nm-LED를 설치하여 왕담배나방의 비상을 억제시키는 점멸패턴을 조사한 결과, 명기 20 ms : 암기 80 ms의 점멸조건에서 유의하게 낮은 비상활성이 관찰되었다. 이것은 20 ms : 80 ms 점멸광이 왕담배나방 복안의 명적응을 촉진시켜 비상행동이 억제된 것으로 추정 된다.
야외에서 점착트랩+성페로몬제lure (Z)-11-hexadecenal：(Z)-9-hexadecenal ＝95：5，0.03mg/RS를 이용하여 무처리구, 연속광, 20 ms : 80 ms 점멸광을 야간 조사하여 왕담배나방 ♂성충의 유인수를 비교한 결과, 20 ms : 80 ms 점멸광에서 가장 낮은 유인수가 관찰되었다. 성페로몬제의 강한 유인에도 불구하고 낮은 유인 수가 관찰된 것으로부터 왕담배나방은 20 ms : 80 ms 점멸광을 기피하는 것으로 추 정된다.
본 연구는가을 국화의 개화지연에 영향을 주지 않으면서 왕담배나방 방제의 가 능성을 시사했다.

Use of conidia or spores of entomopathogenic fungi are influenced by environmental conditions such as temperature and relative humidity and caused slow and fluctuation of mortality. In addition, although the fungi have the advantage of a restricted host range, this specificity is one of the limiting factors for their use. These factors are preventing wider application and use of these biocontrol agents. To mitigate such problems we selected an Beauveria bassiana Bb08 which kill green peach aphid with its liquid culture filtrate. In this study we conducted bioassay with the fungal culture filtrate and culture fluid to greenhouse pests such as cotton aphid, whitefly and thrips. Culture fluid showed high mortality against green peach aphid, as well as cotton aphid, sweet potato whitefly, and western flower thrips. However, control effect of culture filtrate varied with pests. Culture filtrate showed high mortality to cotton aphid. Mortality of western flower thrips with culture filtrate was slower than culture fluid including spores and sweet potato whitefly was much lower. These results indicated that the culture fluid of Beauveria bassiana Bb08 has potential to simultaneously control various greenhouse pests.

Entomopathogenic fungi are natural pathogens of insects and contribute to the regulation of host insect populations in the environment. Several these fungi produce a wide range of secreted enzymes, secreted protein toxins and secondary metabolites to overcome host defenses and ultimately kill the host, and to defend host resources against competing pathogens and saprophytes. Therefore, this study was performed to select the antimicrobial activity of entomopathogenic fungi form Korea soils against plant pathogenic bacteria Ralstonia solanacearum and plant pathogenic fungi Botrytis cinerea using dual culture technique on SDYA. In addition, we also performed to screening of 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals scavenging activity compounds from liquid culture filtrates of entomopathogenic fungi and investigate to it’s anticancer activity. As results, 12 isolates, 6 isolates and 25 isolates showing of these fungal metabolites produced antibacterial, antifungal and radicals scavenging activity compounds, respectively. The preferential antimicrobial and radical scavenging activities give evidence that these entomopathogenic fungal metabolites might be useful as a source for plant pathogen control and pharmaceutical interests.
