Abstract

This study was conducted to investigate the host plants in greenhouse, developmental periods at different temperatures and distribution patterns on cucumber of the greenhouse whitefly, Trialeurodes vaporariorum(TV) in $1984{\sim}1985$. Host plants of 39 species belonging 27 families only in the greenhouse were recorded in 1984. Longevity of adult was 26.8 days and number of eggs per female was 305 eggs at $25^{\circ}C$. The eggs, larval and pupal periods were 8.2, 8.3, 7.5 days respectively at $25^{\circ}C$. The threshold temperature of development from egg to larva was $8.8^{\circ}C$. Survival rates from eggs to adults at $22^{\circ}C,\;25^{\circ}C,\;30^{\circ}C$ were 70.3%, 58.0% and 66.4%, respectively. Adults and eggs were found only on the apical leaves of cucumber plants within 40 days after transplanting. On the other hand, larva distributed on the middle leaves and pupa on the lower leaves.

침입해충(侵入害蟲)인 온실가루이의 분포현황(分布現況), 온도(溫度)가 발육(發育)에 미치는 영향(影響) 및 주내분포(株內分布)에 관(關)한 조사결과(調査結果)는 다음과 같다. 1. 온실가루이는 영구온실내(永久溫室內)의 철쭉, 란타나, 포인세치아 등(等) 27과(科) 39종(種)의 관상식물(觀賞植物)에서 기생(寄生)하였다. 2. 산란전기간(産卵前期間)은 $25^{\circ}C$에서 1.1일(日), 산란기간(産卵期間)은 28.8일(日), 산란후기간(産卵後期間)은 0.5일(日) 성충수명(成蟲壽命)은 26.8일(日)로 $25^{\circ}C$가 적온(適溫)이었고, 숫컷의 성충수명(成蟲壽命)이 약(約) 6일(日) 짧았다. 3. 일당(日當) 산란수(産卵數)는 $25^{\circ}C$에서 9.8개(個), 총산란수(總産卵數)는 305개(個) 였다. 4. 난기간(卵期間)은 $25^{\circ}C$에서 8.2일(日), 유충기간(幼蟲期間)은 8.3일(日), 용기간은 7.5일(日)이었고, 한세대(世代)를 거치는데는 $22^{\circ}C,\;25^{\circ}C,\;30^{\circ}C$에서 각각(各各) 27.5일(日), 23.8일(日), 18.9일(日)로 온도(溫度)가 증가(增加)할수록 짧아지는 경향(傾向)이였다. 5. 난(卵)에서 유충(幼蟲)까지의 발육영점온도(發育零點溫度)는 $8.8^{\circ}C$였다. 6. 난(卵)에서 성충(成蟲)까지의 성공율(成功率)은 $22^{\circ}C,\;25^{\circ}C,\;30^{\circ}C$에 각각(各各) 70.3%, 58.0%, 66.4%였다. 7. 온실가루이 한세대기간(世代期間)동안의 성충(成蟲)과 난(卵)은 상위엽(上位葉)에 유충(幼蟲)은 중위엽(中位葉)에 용은 하위엽(下位葉)에 집중분포(集中分布)하였다.
