아메리카잎굴파리 (Liriomyza trifolii)의 외부기생봉 굴파리좀벌 (Diglyphus isaea)의 생태적 특성 및 저장 조건 구명 = Ecological Characteristics and Storage Condition of Diglyphus isaea(Walker) (Hymenoptera: Eulophidae), an Ectoparasite of Liriomyza trifolii(Burgess) (Diptera: Agromyzidae)

국문 초록 (Abstract)

아메리카잎굴파리 외부기생봉인 굴파리좀벌의 온도별 알, 유충, 번데기 발육기간과 성충의 산란수, 기주체액 흡즙수, 성충수명, 저온 저장력 등을 조사하였다. 굴파리좀벌의 알기간, 유충기간, 번데기 기간은 $25^{\circ}C$에서 각각 1.3일, 4.5일, 6.3일이었다. 성충의 산란수, 기주체액 흡즙수, 성충수명은 $25^{\circ}C$에서 각각 305.3마리, 657.0마리, 25.1일이었다. 아메리카잎굴파리 유충 영기별 굴파리좀벌의 산란선호성과 흡즙선호성을 조사한 결과 각각 90.2%와 82.8%가 3령 유충에 집중되었다. 굴파리좀벌의 저온저장에 따른 50% 생존기간은 꿀물 20%희석 용액을 제공할 경우 $5^{\circ}C,\; 10^{\circ}C,\;15^{\circ}C$에서 각각 180일, 150일, 90일이었다. 굴파리좀벌 저온저장 후 산란수는 저장기간 30일, 70일, 140일에서 각각 190.8개, 104.0개, 89.4개였다.

다국어 초록 (Multilingual Abstract)

Experiments have been performed to investigate biological characteristics of Diglyphus isaea (Walker), an ectoparasite of Liriomyza trifolii (Burgess). At $25^{\circ}C$, development time of D. isaea was estimated as 1.3 days for eggs, 4.5 days for larvae and 6.3 days for pupae. Adult longevity was 25.1 days, and a female adult could lay 305.3 eggs throughout its lifetime. Number of L. trifolii parasitized or killed by the wasp was 962.2 individuals/adult. Most of all parasitized or killed larvae were identified as third instar. With 20% honeyed water as food source, half of the adults could survive 180 days at $5^{\circ}C$, 150 days at $10^{\circ}C$, and 90 days at $15^{\circ}C$. After storing at $10^{\circ}C$ with absolute honey for 30 days, 70 days and 140 days, a female adult in room temperature laid eggs 190.8 individuals, 104.0 individuals and 89.4 individuals, respectively.
