Afghanistan is a producer of high-quality pistachios among the top ten producers in the World. Nowadays, these edible nuts are losing their quality and quantity due to hemipteran insect infestation and their diversity during all growth phases in the country borderline. The expansion of the pistachio pest in Iran has caused concerns for Afghanistan, especially in the provinces of Herat, Badghis, and Takhar which are close to the Iran borders. Hence, this survey was initiated to primarily detect the phytophagous insect pest presence in the pistachio open forest areas and to know what management tools were effectively used in alleviation of the pest infestation. Our findings indicated that galling aphids, aphids, thrips, and root beetles received the maximum positive responses in the Herat province, but psyllids, aphids, root beetles, leave miners, fruit borers and thrips received the highest responses in Badghis province. In addition, Takhar province depicted plant bugs, twig borer moths, galling aphids, leaf miners, and leafhoppers got the most positive responses accordingly. In the meantime, the data showed that management outcomes were not satisfactory despite the use of sanitation, cultural practices, and chemical application. The survey presented significant differences in the prevalence of pest and in the application of pest control methods among the survey regions. Finally, it is essential to develop the strategy of integrated pest management in order to stop the phytophagous insects from turning into actual pests. This will reduce the pistachio loss annually and improve the nut culture quality in Afghanistan.

Global warming and changes in ecosystems are either causing a rapid decline in insect diversity on earth or, on the other hand, are increasing the likelihood of unexpected insect pests emerging. This study summarizes and reports the followings: Introduction to the Insects of Red Data Book of Korea and Nationally Protected species, the establishment of monitoring strategy for exotic insects by the investigation of species distribution range through field surveys and others, the dispersal of exotic insects, and with the expansion of exotic insects and development of ecosystem impact prediction model.

Since the importance of integrated pest management to minimize environmental damage and maximize pest control effectiveness has emerged, efforts to put it into practice have continued. To implement IPM, it is necessary to estimate the economic injury level to determine the control method by identifying pests and weeds that damage the quantity and quality of crops in the field, investigating the occurrence level, and calculating the ratio of cost and effectiveness. Also, damage to host plants caused by increased density of insect pests appears to change plant’s health that key factor for managing crops. Therefore, understanding the relationship between the density of pests and the damage to the host plants is necessary. This study aims to analyze the causal relationship between the density of insect pests and damage to the host plants for estimating the economic injury level of insect pests on the host plants and investigating the possibility of pest control decision-making using plant health status.

소형 곤충으로 좁은 틈새에 있는 총채벌레는 종종 살충제 살포에 노출되기 어렵다. 이에 접촉페로몬을 처리하여 은둔행동을 막으려는 행동 교란 방제 전략을 세웠다. 꽃노랑총채벌레(Frankliniella occidentalis)에서 밝혀진 접촉페로몬은 7-methyltricosane (7TM)으로 본 연구에서는 먹이에 이 물질을 처리하여 행동 교란 유무를 생물검정하였다. 이 접촉페로몬은 유충에게 영향을 주지 않았지만 수컷 성충으로 하여금 처리된 먹 이로부터 회피하려는 행동을 유발하였다. 반면에 암컷 성충에게는 오히려 7TM이 처리된 지역으로 이동하는 행동을 유발하였다. 동일한 접촉페 로몬에 대해서 대만총채벌레(Frankliniella intonsa)에서도 유사한 행동 변화가 관찰되었다. 이러한 7TM에 기인한 총채벌레의 행동 변화를 살충 제 처리와 연결하여 고추를 가해하는 총채벌레류를 대상으로 방제효과를 검정하였다. 스피네토람 살충제 단독 처리에 비해 7TM과 혼합하여 처 리하면 총채벌레류 방제효율이 증가하였다. 흥미로운 점은 7TM 단독 처리로도 대만총채벌레 밀도에 일부 감소 효과를 보여 이 물질이 총채벌레 의 행동교란을 주는 것을 뒤받침하였다. 본 연구는 접촉페로몬 처리로 총채벌레의 살충제 회피 행동을 줄여 방제효과를 높인 새로운 해충방제기 술을 제시한다.
