[The effect of common insecticides on Liriomyza trifolii (Burgess) (Diptera: Agromyzidae)]
Formosan Entomologist 27 (3), 195-205
Abstract: Seedlings of field bean with or without Liriomyza trifolii (Burgess) were used to study the effects of six insecticides (cartap, thiocyclam, triazophos, pyrazophos, abamectin, and cyromazine) on different life stages, of L. trifolii by dipping method. The results showed that all these insecticides have a significant lethal effect on L. trifolii and can be used to control the leaf miner. The highest lethal effect was recorded for the larval stage, with a survival rate of only 0-5.8%. The second most effective period was the adult stage. Cartap and thiocyclam were the most potent compounds, and resulted in almost 0% survival rate, oviposition and feeding. The, remaining four insecticides could only decrease the adults' 24-hour survivability by 2.1-41.0%, reduce the oviposition by 54.1-96.6% and the numbers of feeding stipples by 42.7-97.0%. Partial side effects to female flies, such as decreased longevity, fecundity and feeding stipples of insecticide treated adults beyond 24 hours, also occurred. The stage least affected was the egg stage for all tested insecticides, with a survival rate between 83.5-98.4%.
