昆蟲生長調節劑fenoxycarb和pyriproxyfen對小黃家蟻（Monomorium pharaonis）（Hymenoptera: Formicidae）蟻后產卵量之影響
The Effect of Fenoxycarb and Pyriproxyfen on the Egg Production of the Pharaoh ant Monomorium pharaonis (Hymenoptera: Formicidae)
摘要
在實驗室中試驗兩種昆蟲生長調節劑（fenoxycarb和pyriproxyfen）對小黃家蟻（Monomorium pharaonis (L.)）蟻后產卵之影響，結果小黃家蟻蟻后經處理0.5% fenoxycarb 5週內，產卵量明顯減少，而子代數量於2週內減少，至20週後已無幼蟲出現。以1%及2% fenoxycarb溶於大豆油處理小黃家蟻蟻后，於4週後產卵量減少，且於10週內並沒有復原之情形。1%及2% fenoxycarb處理間並無顯著差異。在實驗室中以0.5%、1%及2% fenoxycarb之處理效果較好，然而在一段時間之後，大部份蟻群仍會恢復正常。經過1%及2% fenoxycarb處理後，若以人為方式補充蟻巢中老熟幼蟲之數量，則蟻后產卵能力能夠在9天內恢復，經過26天之後，與對照組未持續補充巢中老熟幼蟲數量有顯著差異。濃度高於1%之pyriproxyfen處理在3天內便能明顯減少蟻后產卵量，然而在21天後pyriproxyfen便失去抑制效果，蟻后的產卵情形恢復正常。蟻后以0.1%及0.5% pyriproxyfen處理後第6天產卵量開始減少，到第27天已降低到平均約10個卵，與未處理之對照組之間有顯著之差異。0.1%及0.5% pyriproxyfen處理之間並無顯著差異。

The effects of fenoxycarb and pyriproxyfen on the egg production of queens of the Pharaoh ant, Monomorium pharaonis were studied in the laboratory. Fenoxycarb at 0.5% significantly reduced egg production of queen within 5 weeks and quantity of brood within 2 weeks. No larva was found after 20 weeks. Queens in colonies treated with 1% and 2% fenoxycarb in soybean oil laid significantly fewer eggs than the controls 4 weeks after treatment, with no recovery during 10 weeks of the study. No significant difference was found in the responses of the colonies treated with 1% or 2% fenoxycarb. The optimum results were obtained by using concentrations of 0.5%, 1%, and 2% fenoxycarb. However, most of the colonies eventually returned to normal as time progressed. The production of eggs in the colonies treated with 1% and 2% fenoxycarb recovered within 9 days when late instar larvae were added. There were significant differences between queens with or without larvae 26 days after fenoxycarb treatment. Colonies treated with concentrations higher than 1% pyriproxyfen showed a rapid decrease in egg production within 3 days after treatment. However, egg production quickly recovered from the effects after 21 days.Concentrations of 0.1% and 0.5% pyriproxyfen reduced egg production within 6 days. The mean production of eggs decreased to a level of about 10 eggs within 27 days, significantly different from the untreated (control) colonies. However, there was no significant difference between the 0.1% and 0.5% pyriproxyfen treatments.
