小癭蚊對神澤氏葉蟎卵量的取食與產卵反應評估

小癭蚊（Feltiella minuta（Felt））為發生於茄園的葉蟎的捕食性天敵。在28℃、13:11（L:D）光周期的定溫箱中測試其幼蟲在每日供應10、20、40、80、100、120及160粒神澤氏葉蟎卵時的取食反應，日供10或20粒葉蟎卵時，所有幼蟲均在完成發育前逃離測試浮葉；日供食物增至120或160粒葉蟎卵後，所有幼蟲均正常化蛹於測試浮葉上。日供20至120粒葉蟎卵時，幼蟲食量隨食物量的增加而顯著加大，而於日供120粒葉蟎卵時有最高食量。雌成蟲在日供10、20、40、80、120及160粒神澤氏葉蟎卵時的產卵反應，也在相同條件的定溫箱中測試。每日產卵量隨食物量的增加而上升，於每日供應120粒葉蟎卵時達到最高產卵量。幼蟲每日食量及成蟲每日產卵量的SE/mean值均以每日供應120粒葉蟎卵時最低。基於上述結果，作者認為120粒葉蟎卵為小癭蚊的每日食物需求量。

Feltiella minuta (Felt) is a predator of spider mites found on eggplant. Feeding responses of the larval stage to a daily supply of 10, 20, 40, 80, 100, 120, and 160 eggs of Tetranychus kanzawai Kishida were tested at 28℃ with a photoperiod of 13:11 (L:D) in an incubator. When provided with 10 and 20 spider mite eggs daily, all tested larvae escaped from the leaf arena before the completion of development. For the daily food supply increased to 120 and 160 spider mite eggs, all tested midges pupated on the test leaf arena. With a food supply scheme of 20-120 spider mites eggs, the daily food consumption of the tested larvae increased significantly with an increase in food supply and was maximized when 120 spider mite eggs were offered daily. The ovipositing responses of adult female flies to a daily supply of 10, 20, 40, 80, 120, and 160 spider mites eggs were also tested in an incubator at the same settings. The daily fecundity of tested flies increased with increments in the food supply, and peaked at a daily supply of 120 spider mite eggs. Values for the standard error over the mean of daily food consumption of larvae and the daily fecundity of adult females were both lowest at the daily food provision scheme of 120 spider mite eggs. Based on the above data, we suggest 120 spider mite eggs as the daily food requirement of F. minuta.
