Abstract:   (1452 Views)
The aim of this study was to evaluate the efficacy of some insecticides with novel modes of action on Liriomyza sativae Blanchard and their sublethal effects on pupal mortality, pupal weight and sex ratio in adult insects. The effects of hexaflumuron, chromafenozide, chlorfluazuron, cyromazine, lufenuron + fenoxycarb and azadirachtin and chlorantraniliprole were evaluated on 1st instar larvae of L. sativae using a leaf dip method. Dose - response lines were constructed for insecticides which caused higher mortality of the larvae at field recommended doses. LC50 values for chlorantraniliprole, cyromazine, azadirachtin and hexaflumuron were 0.24, 0.49, 8.51 and 67.6 mg ai/l, respectively. A significant reduction in pupal weight and adult emergence was observed in all of the treatments except chromafenozide; but the adult sex ratio did not change significantly compared with control. Most of the insecticides used in this study are fairly new compounds with unique modes of action and had considerable lethal and sublethal effects on L. sativae. If these results also hold true in the field and commercial greenhouse conditions, these compounds could be suitable candidates in management of vegetable leafminer.
