The life history and development of Tetrastichus sp. parasitizing fallwebworm pupa in Korea were studied. The mean lifetime fecundity was 94.7 with a maximum of 125, and the portion of female progeny averaged 90.3%. A male and a female lived for an average of 19.8${\pm}$4.5 and 21.7${\pm}$4.2 days, respectively. The duration of development for each stage was as follows: egg, 2 d; the 1st instar larva, 2${\pm}$1 d; the 2nd instar larva, 2${\pm}$1 d: the 3rd instar larva, 3${\pm}$1 d; the 4th instar larva, 6${\pm}$2 d; and pupa, 8${\pm}$2 d. Total developmental duration from hatching of the larva to adult emergence required 21.1${\pm}$3.7 d, and females took 1-2 days more than males in the incubator (28$^{\circ}C$, 70% RH, and 16:8 LD).

Nesolynx thymus Girault (Hymenoptera: Eulophidae) is one among 20 hymenopteran parasitoids reported to attack the uzi fly, Exorista bombycis, which in turn infests the silkworm, Bombyx mori accounting a cocoon yield loss of 10-20%. A host of factors viz., age and size of host, age and size of parasitoid, availability of host, temperature and quality of host are reported to influence the reproductive efficiency of the parasitoids. In the present study an attempt was made to record the influence of foraging parasitoid density on their reproductive performance. Three day-old uzi pupae were offered to varying numbers (1 - 10) of 2 day old Nesolynx thymus adults for parasitization. The progeny production per pupa (84.44 - 132.77) increased significantly with increase in the number of foraging parasitoid adults (1 - 10) however, progeny production per female decreased. The sex ratio (M : F) (1:25.49 - 1:1.53) decreased significantly with increase in foraging parasitoid adults. The morphometric parameters except female abdomen width of first generation parasitoid showed significant negative correlation with number of foraging adults. However, correlation between the parasitoid size in first generation and their reproductive performance was nonsignificant.

아메리카잎굴파리의 내부기생봉인 Neochrysocharis formosa의 산란과 기주체액섭취 선호성을 조사하였다. N. formosa는 기주유충의 몸 뒤쪽에 대부분 산란하였다. 온도 조건에 따른 일산란수와 일기주체액섭취수를 조사한 결과 온도가 높을수록 증가하는 경향이었으며 15, 20, 25, 3$0^{\circ}C$에서의 산란수와 체액섭취수의 비율은 각각 0.5, 0.9, 1.0, 1.0이었다. $25^{\circ}C$ 항온조건하에서 N. formosa의 총산란수와 기주체액섭취수는 각각 176개 188.7개이었으며 산란수와 기주체액섭취수 비율은 0.9이었고 암컷 수명은 11.8일이었다. 산란과 기주체액섭취는 주로 아메리카잎굴파리 3령유층을 선호하였다.

The present investigation was conducted to know the effects of host age on development and morphological characteristics of Nesolynx thymus, a gregarious ectopupal parasitoid of the uzi fly, Exorista bombycis, a serious en do-larval parasitoid of the silkworm, Bombyx mori L. For experimentation, 3 - 11 day-old pupae of E. bombycis were exposed to 2 day-old adults of N. thymus at $25{\pm}2^{\circ}C\;and\;60{\pm}10%$ RH. A highly significant negative correlation between host age and the following development and morphological characteristics of the parasitoid was observed: number of pupae parasitised, total adult recovery, sex ratio and recovery, longevity, body length, wing span, abdomen length, and abdomen width of females. The findings of the present study clearly demonstrate that various development and morphological parameters of N. thymus are influenced by the age of E. bombycis pupae.

Pollinators play important roles for crop production as well as maintenance of wild plants' reproduction. Pollinator dependency in Korean agriculture have increased, but the degradation of habitat quality pose significant threats to pollination in agroecosystem. Provisioning flower habitat is one of the major activities to increase pollinator abundance and richness. We tested the effect of flower habitat supplementation on the pollinator, pest and natural enemy abundance in pepper field. Results showed that Hymenopteran pollinators were more abundant in the pepper plots close to the flower habitat. Among natural enemies, the similar pattern from pollinators was observed to parasitoids in the family of Eulophidae, but not to those of Ichneumonidae. There were no statistically significant differences of insect pests like aphids and thrips, as well as pepper production among plots in the pepper field. Even limited spatial scale, this study showed supplementing the flowering plant habitat to the agricultural landscape could conserve and boost pollinators and natural enemies, and possibly resulting better fruit production by pollination service.

Life table studies were conducted in the laboratory for the eulophid gregarious pupal parasitoid, Tetrastichus sp., on Hyphantria cunea Drury at a constant temperature of 28.2$\pm$2$^{\circ}C$, 50-60% RH to evaluate their impact on the host and their potential biological control. Development of immature stage took 20.1$\pm$2.7 d: adult females lived for 23.2$\pm$2.2 (range, 16-27)d and produced a mean of 53.6$\pm$26.6 adult progeny per female, with a sex ratio of 1: 9.5 (M:F). The intrinsic rate of natural increase (r$_{m}$) was 0.178/ female/day; the net reproductive rate (R$_{o}$), 46.74; the capacity for increase (r$_{c}$) 0.177; the finite rate of increase (λ) 1.19/female/day; thus each female contributed 46.74 individuals to the population in a mean generation time of 21.6 d. Biological factors in determining the life history trait variation of the parasitoid were discussed.d.d.d.

Tetrastichus sp.는 미국흰불나방의 번데기 기생벌로서, 1개의 숙주에 여러마리의 자손을 번식하는 집단 기생벌이며, 일년에 여러 세대 발생한다. 작잠, 신생아용 분유, 난황, 로얄젤리 등을 주요성분으로 기생벌의 인공먹이를 조성하였으며, polypropylene필름으로 번데기형태를 만들어 인공숙주로 사용하였다. 인공숙주에서 발육한 기생벌은 자연숙주에서 자란 기생벌보다는 크기가 작았으나, 계대 사육으로 번식 가능한 자손을 생산하였다. 인공숙주에서 발육한 in vitro 2세대의 생물학적 특성은 in vitro 1세대보다 훨씬 개선 었다. 평균 자손 수, 산란기간, 수명 등은 in vitro 에서 45.7,7.8, 13.8일 이었고 암컷 편중의 성비 76.9%를 나타내었다. 이러한 결과는 Tetrastichus sp.가 in vitro 대량사육에 적합한 기생벌임을 보여준다.
