藥劑對蔬菜斑潛蠅(Liriomyza sativae Blanchard)（雙翅目：潛蠅科）之藥效探討
Effect of Common Insecticides on Liriomyza sativae Blanchard (Diptera: Agromyzidae)
摘要
以帶蟲或不帶蟲菜豆苗(Phaseolus vulgaris var. communis Aeschers)浸漬法(dipping method)測試歐殺滅(oxamyl SL)、阿巴汀(abamectin EC)及賽滅淨(cyromazine SL, WP)等藥劑對蔬菜斑潛蠅(Liriomyza sativae Blanchard)未成熟期與成蟲期之影響。結果得知上述三種藥劑均對蔬菜斑潛蠅具顯著之致死效果，確可供該蠅防治用。歐殺滅與阿巴汀對蔬菜斑潛蠅各蟲期之防治效能，均以卵與幼蟲期最高，致死率為100%，其次為成蟲期。雌蟲接觸上述二種藥劑24小時，其間其存活率、產卵數及取食刻點數，不僅各受到18.3~26.0、97.3~98.9及95.2~97.3%之抑制，尚對雌蟲接觸藥劑24小時後之壽命、子代成蟲數及取食刻點數，各達50.3~62.9、95.5~98.9及89.3~99.9%之抑制。賽滅淨兩種劑型對蔬菜斑潛蠅各蟲期之防治效能，則以幼蟲期最高，致死率達100%；卵期次之，對孵化率雖無影響，但對其後第一、二及三齡幼蟲之致死率，各為60.6~64.0、94.2~98.2及100%；成蟲期受藥劑影響較低，雌蟲接觸此藥劑不同劑型24小時，其間藥劑對雌蟲存活率、產卵數及取食刻點數等，雖均無顯著直接影響，但對雌蟲接觸藥劑24小時後之子代成蟲數與取食刻點數，各達73.9~85.2與73.4~75.9%之抑制。

Seedlings of field bean (Phaseolus vulgaris var. communis Aeschers) with and without the leaf miner (Liriomyza sativae Blanchard) were used to study the effects of three insecticides (oxamyl SL, abamectin EC, cyromazine SL, and cyromazine WP) against the different life stages of L. sativae by dipping method. The results showed that all these insecticides have a significant lethal effect on L. sativae and can be used to control the leaf miner. The highest lethal effect of oxamyl and abamectin was recorded for the egg and larval stages with a survival rate of 0%, and the second most effective period was the adult stage. The adult-24-hour survival rate, the number of eggs and number of feeding stipples were reduced by 18.3-26.0, 97.3-98.9 and 95.2-97.3%, respectively, and the longevity, adult progeny and the number of feeding stipples after 24 hours also decreased by 50.3-62.9, 95.5-98.9 and 89.3-99.9%, respectively. The highest lethal effect of the two cyromazine formulations was recorded for the larval stage with a survival rate of 0%; the second most effective period was the egg stage, although hatching was not affected, while the larval mortality of the 1st, 2nd and 3rd instars was 60.6-64.0, 94.2-98.2 and 100%, respectively. The least affected was the adult stage with no direct effect on the adult-24-hour survival rate and the number of eggs and number of feeding stipples. However, the adult progeny and the number of feeding stipples after 24 hours decreased by 73.9-85.2 and 73.4-75.9%, respectively.
