Susceptibility of males and females of cucumber fruit fly, dacus ciliatus, to various insecticides in the laboratory conditions

Abstract EN

The cucumber fly, Dacus ciliates Loew., is a destructive pest of cucurbit crops in some regions of Iran.

Susceptibility of adults of D.

ciliates to various insecticides (deltamethrin, dimethoate, trichlorofon, spinosad, acetamiprid, and malathion( was investigated.

The insecticide toxicity was tested through contact method in three stages (males only, females only, and a mixture of males and females).

The results showed that the used insecticides excellently affected on males and females of D.

ciliates through contact toxicity.

Also, their effect on the mixture of males and females was acceptable.

In addition, dimethoate and deltamethrin were better than the others.

The LC50 values of these two were less than 1 mg L-1.

Also, except for acetamiprid, LC50 vales of all other insecticides on males and females were close.
