Leaf cutting-patterns and general cradle formation process of thirteen Apoderinae (Coleoptera: Attelabidae) in Korea: Cradles of Attelabidae in Korea I

The distinctive feature of leaf‐rolling weevils is their special care for their progeny. In many species among the family Attelabidae, the female recognizes the size and shape of the leaf of the host‐plant and does the leaf cutting by a definite method. The location of cutting line, length and shape becomes the basic information in understanding the most fundamental structure of females recognition process and cradle formation strategy. Leaf cutting is not only the process of withering the leaf by blocking the water flow along the main vein but also the process of making reversal easy at the leaf‐blade part. The difference in forms of cutting line, leaf blade, interval or dispersion of nibble marks on the stem and pitch of leaf rolling has effects on the shape of the completed cradle. In the present paper we provide leaf‐cutting patterns and the cradle formation process for 13 species of subfamily Apoderinae. We also provide a pictorial key of the cradle for the first time in Korea.

Predatory Capability of Chilocorus kuwanae (Silvestri) (Coleoptera: Coccinellidae) for Saissetia coffeae (Walker) (Hemiptera: Coccidae)

This study, examined Chilocorus kuwanae for biological control of Saissetia coffeae. We measured basic developmental characteristics of C. kuwanae and its capability to prey on the second-instar larvae of S. coffeae by indoor breeding under the following conditions: , humidity , and day length 16L : 8D. The average daily consumption of the second-instar larvae of S. coffeae by C. kuwanae adults was approximately 77.5 larvae/day, which was significantly 2.8 and 2.9 times higher than consumption by Chrysoperla carnea and Cryptolaemus montrouzieri, respectively. During the nymphal period, C. kuwanae consumed a total of 659.0 second-instar larvae of S. coffeae. The interaction between C. kuwanae and the second-instar larvae of S. coffeae varied according to their densities, with the increase in C. kuwanae consumption rate noted to decelerate and gradually level off at the maximum, rsembling Hollings Type II functional response. Duration of egg to adult development varied from 21.1 days to nearly 27.9 days at temperatures of . Hatchability, pupation rate, and adult emergence were greater than 72.3%, 77.8% and 83.3%, respectively.

Occurrence of Fruit Flies (Diptera: Tephritidae) in Fruit Orchards from Myanmar

Population of fruit flies was monitored by using methyl eugenol trap during 2010-2011 in Yezin, Myanmar. Population numbers were analyzed with meteorological factors including rainfall, temperature, relative humidity and duration of sunshine. Samples of mango, guava, and jujube fruits were collected from orchards. The fruits were kept in containers so that the species of flies infesting the fruit could be identified when the adult insects emerged and to assess damage caused by fruit flies. Regression analyses indicated that populations of fruit flies were observed to be positively correlative with rainfall, minimum temperature and relative humidity, and negatively correlative with the duration of sunshine. Eleven species of fruit flies, Bactrocera arecae, B. carambolae, B. correcta, B. dorsalis, B. kandiensis, B. latilineola, B. malaysiensis, B. neocognata, B. raiensis, B. verbascifoliae, and Carpomya vesuvina, were identified. B. correcta and B. dorsalis were the most abundant and accounted for 29.3% and 28.6% of total emerged adults in the different fruit samples. The highest percentage of fruit damage was observed on guava (), followed by mango () while the lowest was recorded on jujube ().

Terrestrial Insect Diversity of the Donggang River in Korea

This study was carried out to investigate the terrestrial diurnal insects in the Donggang river neighborhood. A total of 455 species belonging to 117 families of 16 orders were identified from 3,001 collected terrestrial insects around the Donggang river. Species richness showed as follows; Coleoptera (166 species, 34.48%), Hemiptera (11 species, 24.0%), Lepidoptera (68 species, 14.95%), Diptera (40 species, 8.79%), Hymenoptera (28 species, 6.15%), Orthoptera (18 species, 3.96%), Odonata (7 species, 1.54%), and others (3.74%). The Coleoptera consisted of the most number of individuals (33.2%), followed by 951 Hemiptera (31.7%), 662 Lepidoptera (20.7%), 155 Orthoptera (5.2%), 100 Diptera (3.3%), 87 Hymenoptera (2.9%), 30 Odonata (1.0%) and others (2.0%). Among them, 1 endangered species of Ministry of Environment, 1 Critically Endangered Korean species, 7 Vulnerable Korean species (VU), and also 2 Near Threatened Korean species were surveyed in the Donggang river neighborhood.

Larva of Lilioceris (Lilioceris) ruficollis (Coleoptera: Chrysomelidae) from Korea

Detailed morphological descriptions and illustrations of the last instar larva of Lilioceris (Lilioceris) ruficollis (Baly, 1865) with the host species, Dioscorea spp., are presented for the first time. Taxonomical and ecological remarks on their biology are also given herein.

Effect of Covering the Soil with Naturally Degrading Polymer Film on the Benthic Macroinvertebrates Community Structure in Paddy Field

This study was conducted to investigate the influence of natural degrading polymer film covering in rice paddies on the benthic macroinvertebrate community structure in Dangsu-dong, Suwon, Gyeonggi-do from May 2009 to September 2009. We compared 5 treatments: golden apple snail farming (GF), natural degrading polymer film + organic farming (NOF), natural degrading polymer film + chemical farming (NCF), conventional farming (CF), and no fertilization (NF) as the control. The total number of species was highest in NOF followed by GF, NF, NCF, and CF. The total number of individuals was highest in NOF followed by NCF, CF, NF, and GF. The Dominance index (DI) ranged from 0.43 to 0.95. The highest dominance index was in GF followed by NCF, NF
