Phytophagous insects were surveyed for biological control of weeds in the southern part of korea from April 20 to July 31, 1987. Phytophagous coleopteran insects representing 12 families, 52 genera and 61 species, hemipteran insects 7 families, 18 genera and 20 species, homopteran insects 4 families, 16 genera and 21 species, hymenopteran insects 2 families, 2 genera and 3 species, and orthopteran 2 familes, 6 genera and 6 species were recorded from 58 weeds. Some chrysomelids and orthopteran insects were potential agents for biological control of weeds.

Two species of the genus Indomegoura Hille Ris Lambers (Hemiptera: Aphideidae) are recognized in Korea, including I. nigrotibiae (Tao, 1963) new to Korean Peninsula, Besides the descriptions, the host plants nad the key to the species of genus Indomegoura are provided and the biology of each of each species are discussed.

Asian gypsy moth, Lymantria dispar asiatica (Lepidoptera: Erebidae), which is an indigenous pest in Korea, a large outbreak has been reported in Gyeonggi-do, Chungcheong-do, and northern Gyeongsangbuk-do from 2019 in forest and nearby downtown areas, causing emotional damage to forests and city dwellers. During the indoor culture of gypsy moth eggs collected in Yecheon, Gyeongbuk in 2021 we found that 79.65% (321/403 of first instar larvae) were died due to Lymantria dispar multiple nucleopolyhedrovirus (LdMNPV) infection. Sequence analyses of 36 gypsy moths collected from 12 regions in Korea using LdMNPV late expression factor-8 (lef-8) and polyhedrin (polh) genes showed a genetic variation of 0.80% and 0.86%, respectively. Comparison to GenBank data showed that the Korean samples were most similar to LdMNPV in Japan, whereas most different to those of Turkey. These results showed a high infection rate of LdMNPV in Korea and LdMNPV is one of the important population regulators of the gypsy moth.

This study was carried out to investigate the distribution of forest insect pests of Dobongsan in Bukhansan Nation Park. A total of 76 species of forest insect pests belonging to 29 families under 5 orders were collected in these areas: 24 species 9 families in Lepidoptera; 23 species 9 families in coleoptera; 20 species 4 families in Homoptera; 6 species 5 families in Hemiptera, and 3 species 2 families in Hymenoptera. These were 66 species of 28 families under 5 orders found in Songchoo-gol, and 41 species of 19 families under 5 orders found in Hoeryong-gol. Key foest insects for control pests were confirmed to be Platypus koryoensis, Arcte coerulea, Erannis golda, and Isyndus obscurus was classified predaceous natural enemy.

Gypsy moth (Lymantria dispar), a polyphagous insect pest belonging to the family Lymantriidae, is widely distributed in Korea, Japan, Siberia, Europe, and North America. They pose a threat to various host plants including pear trees, apple trees, and blueberries. Traditionally considered a forest pest, the increasing incursion of gypsy moths into agricultural land near forested areas has intensified damage to crops lacking effective control methods. This study aimed to investigate the temperature-dependent development of gypsy moths to enhance outbreak prediction and advance technology development. The effects of temperature on development of each life stage were investigated under constant temperature conditions of 18, 21, 24, 27, 30, and 33℃ (14L:10D, RH 60±5%) utilizing egg masses collected in Jeollanam-do Jangheung-gun in 2021. The results revealed that higher temperatures accelerated the development rate of the gypsy moth larvae with optimal development occurring at 30℃. However, the survival rate was lowest at 33℃. At the favorable temperature of 30℃, the total development period was 43.8 days for females and 42.5 days for males. The developmental threshold temperature were 13.1℃ for females and 12.5℃ for males, with effective accumulated temperature of 641.1 DD and 657.8 DD, respectively.

Insect pests and their natural enemies of Hibiscus Linne (Malvaceae) were investigated from March 2002 to November 2004. Fourteen insect pest species of 9 families in 5 orders were collected from Hibiscus syriacus: 5 species in Homoptera, 3 species in Lepidoptera, 2 species in Coleoptera, 1 species in Orthoprera, 1species in Hemiptera, 1 spedies in Acarina, and 1 species in Stylommatophora. Especially, Aphis gossypii Glover (Aphididae), Anomis megogona Walker(Noctuidae) and Tetranychus urticae Koch (Tetranychidae) were very important species because of their increasing daminge. The highest donsities were observed from May to June in August in Tetranychus urticae. As the enemies and ento-mopathogens of insect pests on Hibiscus syriacus, 1 species of bacteria, 3 species of fungi, 1 species of fungi, 1 species of Hemiptera, 1 species of Coleoptera, 2 species of Hymenopetera, 2 species of Diptera, and 1 species of Acarina were investigated. As the predators and parasitoids of Aphis gossypii, Aphidoletes aphidoletes aphidimyza Rondani (Cecidomyiidae), Meliscaeva cinctella Zetterstedt (Syrphidae), Harmonia axyridis Pallas (Coccinellidae), and Aphidius gifuensis Ashmead (Braconidae), entomopathogenic fungi, Vericillium lecani naturalis strain (Moniliaceae) and Beauveria bassiana naturalis strain strain (Hypocreaceae) were observed and Bacillus thuringiensis naturalis strain (Bacillaceae), B. bassiana, Metarhizium anisopliae naturalis strain (Hypocreaceae), predators of Tetranychus urticae, Amblyseius sp. (Phytoseiidae), and Orius sp. (Anthocoridae) were observed.

An aphid species, Glyphina betulae( Linnaeus, 1758), which has been known only in western Paleoarctic, is recognized from Mt. Baekdu-san, North Korea. Besides the descriptions and illustration for apterous viviparous female and alate viviparous female, brief biology, host plahts and distribution are discussed. This is the first record of the genus Glyphina in Korean Peninsula.

This study on Pemphigidae was based on the specimens collected from May 1989 to April 1993, at 16 localities of southern part of Korean Penninsula. As a result, 11 species of 7 genera were identified. Of these, four species (Colophina zelkovae, Prociphilus chaenomelis, Tetraneura pumilae, T. iriensis) are new to science. These four species were described and drawn.

Sinomegoura citricola (van der Goot, 1917) is recognized on Citrus unshiu Markovich (Rutaceae), Photinia glabra (Thunb.) Maxim (Rosaceae), and Cinnamomum lourelirii Nees (Lauraceae) from Jeju-do, Korea.
