쌀바구미류(Sitophilus spp.)에 대한 분류학적 정립의 모호함과 쌀바구미(S. oryzae; rice weevil)와 어리쌀바구미(S. zeamais; maize weevil)를 외부형태적 특징으로 구별하기 어려워 2000년 이전까지 국내 저장 쌀에 발생하는 바구미와 관련하여 보고된 거의 대부분의 문헌들은 쌀바구미(S. oryzae)로 다루어졌다. 그 후, 분류학적 재정립과 쌀바구미와 어리쌀바구미의 생식기 구조상 차이로 확실하게 구별이 가능하여 국내 여러 기관들이 소장하고 있던 쌀바구미류 표본들을 검경한 결과, 모두 어리쌀바구미(S. zeamais)로 동정되었고, 쌀바구미(S. oryzae) 표본은 확인되지 않았다(홍 등, 2001). 그러나 2015~2016년 전국의 미곡처리장(RPC) 및 저장창고에 발생하고 있는 저곡해충을 조사하는 과정에서 충북 청주와 보은, 전북 군산, 전남 장성 소재의 창고에 저장된 쌀에서 쌀바구미(S. oryzae)의 발생을 확인함으로써, 앞으로 쌀바구미류를 정확하게 구별할 수 있도록 성충의 생식기 및 유충의 아랫입술수염 형질을 비교하는 한편, 종 특이프라이 머를 이용한 구별방법을 제공한다.

Coccoidea or scale insects are typically small phloem feeders; they are found on various parts of their host plants, and may infest leaves, twigs, branches and roots, in agricultural, forest and ornamental ecosystems worldwide. Many are highly damaging to their hosts, but others produce useful dyes, or valuable secretions in the form of waxes and resins. Between 2015 and 2016, scale insects were collected intensively in central, northern and southern Laos, resulting in a totally of 71 species belonging to 7 families of Coccoidea. Among these are 25 species recorded from Laos for the first time, they are almost pests, but Kerria lacca (Kerr) an economic species which produces shellac for export.

Coccoidea are some of the most potentially detrimental pests for agriculture and ornamental plant industries worldwide, including in Laos. Between January 2015 and August 2016, scale insects were collected on variety of hosts. Previously, the known Coccoidea fauna of Laos comprised 35 species. These most recent collections boost the tally to 49 species belonging to 5 families of Coccoidea. Among these, 19 species are here recorded from Laos for the first time: [Coccidae] Ceroplastes floridensis,Ceroplastes rubens, Coccus capparidis, Drepanococcus chiton, Megapulvinaria maxima, Pulvinaria psidii, Saissetia coffeae; [Diaspididae] Aonidiella citrina, Aonidiella inornata, Fiorinia coronate, Lepidosaphes tokionis, Parlatoria proteus; [Lecanodiaspididae] Psoraleococcus multipori; [Monophlebidae], Icerya aegyptiaca; [Pseudococcidae], Phenacoccus madeirensis, Planococcus ficus, Pseudococcus aurantiacus, Pseudococcus baliteus and Rastrococcus jabadiu. All of these newly recorded species occur elsewhere in south-east or east Asia, including countries contiguous with Laos.

Suborder Psocomorpha belongs to Psocoptera is one of minor order. Psocids occupy a wide range of habitats, from living as indoor, if outdoor most are presented on bark or foliage of dead or leaving tree and shrubs. All specimens of Psocomorpha that found in the field were putted into 75% of alcohol. Preparation and dissection were done before identification. Previously the list of Psocomorpha comprised 14 species. This most recent collection found nine species. Among of them, two species belong to two families; [Amphipsocidae] Amphipsocus japonicas (Enderlein, 1906) and [Psocidae] Psococerastis tokyoensis (Enderlein, 1906) are report in Korea in the first time.

캄보디아와 라오스에는 지금까지 가루깍지벌레과 25종 및 18종이 각각 보고되어 있다. 2015년 이들 지역에서 가루깍지벌레과14종이 채집 되었으며, 그 중 캄보디아에서 2종[Antonina graminis (Maskell, 1897), Coccidohystrix insolita (Green, 1908)], 라오스에서 5종[Nipaecoccus viridis (Newstead, 1894), Paracoccus marginatus Williams & Granara de Willink, 1992, Phenacoccus solani (Ferris, 1918), Rastrococcus iceryoides (Green, 1908)]을 처음으로 보고한다.

Coccoidea (scale insects and mealybugs) are some of the most potentially detrimental pests for agriculture and ornamental plant industries in worldwide and the same in Cambodia and Laos. Scale insects were collected on branches, leaves, peduncles, petioles and fruits of hosts in January to July, 2015 and February, 2016. Previously, Coccoidea fauna of Cambodia and Laos comprise 41 and 35 species respectively. Recently we collected 25 species belong to 3 families of Coccoidea. Among these, nine species are first found in these countries; [Coccidae] Ceroplastes ceriferus (Fabricius, 1798) in Laos, Ceroplastes stellifer (Westwood 1871) in Cambodia, Milviscutulus mangiferae (Green, 1904) in Laos and Cambodia, [Pseudococcidae] Kiritshenkella sacchari (Green, 1900), Phenacoccus parvus (Morrison, 1924 ) in Laos, Palmicultor lumpurensis (Takahashi, 1951) in Cambodia, Rastrococcus invadens (Williams,1986) in Cambodia and Laos, [Diaspididae] Aulacaspis tubercularis (Newstead, 1906) in Cambodia, Aonidiella aurantii (Maskell, 1879) in Laos and Cambodia.

Previously study of mealybug faunas of Cambodia and Laos were known to comprise 25 species and 18 species, respectively. Recently, we have collected fourteen mealybug species in Cambodia and Laos from June to July, 2015. Among them, six species are first found in these countries: Coccidohystrix insolita (Green) in Cambodia; and Antonina graminis (Maskell) in both countries; Nipaecoccus viridis (Newstead), Paracoccus marginatus (Williams & Granara de Willink) Phenacoccus solani (Firris) and Rastrococcus iceryoides (Green) in Laos.

가루깍지벌레는 열대지역에서 일반적인 해충으로 관상식물과 과수류의 큰 문제를 일으키는 해충이다. 캄보디아와 라오스에는 현재 가루깍지벌레과 22종 및 12종이 각각 보고되어 있다. 최근 이들 지역에서 가루깍지벌레과 연구를 수행하여 13종이 채집되었으며, 그 중 캄보디아에서 3종인 Dysmicoccus neobrevipes (Beardsley, 1959), Phenacoccus solani (Ferris, 1918), Rastrococcus iceryoides (Green, 1908) 와 라오스에서 6종인 Dysmicoccus neobrevipes (Beardsley, 1959), Paracoccus invectus (Williams, 2004), Phenacoccus solenopsis (Tinsley, 1898), Planococcus litchi (Cox, 1989), Planococcus minor (Maskell, 1897), Pseudococcus jackbeardsleyi (Gimpel & Miller, 1996)가 이들 국가로부터 처음 보고된다.

The family Pseudococcidae or mealybugs (Hemiptera) are common pests in tropical region of the world and also considered as important pests on ornamental plants and fruit trees. The mealybug faunas in Cambodia and Laos were known to nineteen species and eight species, respectively (ScaleNet, 2014; CABI, 2015; FAO-IPM, 2014). Recently, we have collected thirteen mealybug species in Cambodia and Laos. Among them, seven species of mealybug are found for the first time: Phenacoccus solani (Ferris, 1918) and Rastrococcus iceryoides (Green, 1908) in Cambodia; Dysmicoccus neobrevipes (Beardsley, 1959) and Phenacoccus solenopsis (Tinsley, 1898) in both counties; Paracoccus invectus (Williams, 2004), Planococcus minor (Maskell, 1897) and Pseudococcus jackbeardsleyi (Gimpel & Miller, 1996) in Laos.
