The effects of the genetically modified virus-resistant pepper (line: H15) and the Non-GM pepper (line: P2377) on the insect community in the pepper cultivation area were evaluated. Sampling was conducted using yellow sticky traps and pheromone funnel traps in Anseong and Deokso fields. Total number of insects caught on sticky trap were 3924 individuals at GM pepper and 3670 individuals at Non-GM pepper in Anseong and 2362 individuals at GM and 2528 individuals at Non-GM in Deokso, respectively. The total number of the insect individuals caught by sticky trap was not shown significant differences between GM and Non-GM pepper at Anseong and Deokso fields, respectively. The number of aphids per sticky trap ranged from 11.60±2.02 to 1.92±0.96 at Non-GM and from 11.56±2.15 to 0.33±0.23 at GM in Anseong, and from 2.78±1.22 to 0.11±0.08 and from 2.73±0.84 to 0.11±0.08 at Non-GM and GM pepper in Deokso, respectively. There were no significant differences in seasonal occurrences of aphids caught on sticky traps in GM and Non-GM pepper at both fields, and significant differences in aphids population density between Non-GM and GM were not observed.

The life table statistics of diamondback moth on the transgenic Chinese cabbage (line: SKCP) with myrosinase gene was compared with that on the non transgenic Chinese cabbage (line: SC) at 25±1℃. Adult life span and number of progeny of P. xylostella on the SC and SKCP lines were similar to each other. The sex ratio, developmental period, intrinsic rate of increase and finite rate of increase of P. xylostella on SC and SKCP were not significantly different in both treatments (sex rati t=-1.60; df=220; P=0.1108, developmental period: t=-0.55; df=220; P=0.5803, intrinsic rate of increase: t=-0.11; df=45; P=0.9172). However, the finite rate of increase and net reproduction were significantly different in between SC and SKCP lines (finite rate of increase: t=2.26; df=45; P=0.0287, net reproduction: t=2.08; df=45; P=0.0442).

Effects of host density and refuge on the sex ratio of progeny of hymenopterous parasitoids was tested with Bracon hebetor Say parasitizing Plodia interpunctella (Hübner). The overall sex ratio (male/total) of progeny produced per female with and without refuge was estimated to be 0.49 and 0.41, respectively. Regardless of refuge, the sex ratio decreased as host density increased. But, at host density of 128 with refuge the sex ratio was significantly lower than that without regfuge (t=-2.17, df=24; P=0.040). The number of pupae per host larva with refuge was similar to that without refuge at the host densities tested (t=-0.10, df=53.4; P=0.921). The number of attacked host larvae showed significantly different at all host densities with and without refuge (t=-3.33, df=209; P=0.001).

The effects of the genetically modified virus-resistant pepper (line: 15, 20) and the non-GM pepper (line: 2377, 915) on the insect community in the pepper cultivation area were evaluated. Sampling was conducted using yellow sticky traps and pheromone funnel traps in Anseong and Deokso fields. Total number of insects caught on sticky trap were 3273 individuals at GM pepper and 2949 individuals at non-GM pepper in Anseong and 4357 individuals at GM and 3712 individuals at non-GM in Deokso. Total number of aphids collected on leaves were 451 and 330 individuals at GM and non-GM pepper in Anseong, respectively and 79 individuals at GM and 41 individuals at non-GM pepper in Deokso. The total number of the insect individuals caught on sticky trap was not shown significant differences between GM and non-GM pepper at Anseong and Deokso fields, respectively. Also, there were no significant differences in seasonal occurrences of aphids caught on sticky traps in GM and non-GM pepper at both fields. This work was supported financially by Biogreen21 project of Rural Development Administration (No. 20070301-034-010).

The effects of the transgenic Chinese cabbage (SKCP19 line) with myrosinase gene and Chinese cabbage (SC19 line) without gene introduction on the insect community were evaluated. Sampling was conducted using yellow sticky traps and wing pheromone traps in Anseong and Deokso fields, respectively. The total number of individuals caught by sticky trap was not shown significant differences between transgenic Chinese cabbage and non transgenic Chinese cabbage at Anseong and Deokso fields, respectively (t=0.72; df=46; P>0.05, t=0.38; df=38; P>0.05). Also, There were no significant differences in density of Plutella xylostella population caught by pheromone traps on transgenic and non transgenic cabbage at both fields (t=0.59; df=22; P>0.05, t=0.52; df=18; P>0.05).
