The effects of sublethal concentrations of indoxacarb on Plutella xylostella (L.) (Lepidoptera: Yponomeutidae) were examined. In comparison with the control, sublethal concentrations led to a significant decrease in adult emergence, the percentage of pupation and pupal weight of the parent generation, fecundity, and adult longevity. They also significantly(More)
Use of insecticides can have disruptive effects on the environment. Replacing the chemical compounds in these insecticides with plant materials, however, can be a safe method with low environmental risk. In the current study, chemical composition and insecticidal activities of the essential oil from cardamom, Elettaria cardamomum L. (Maton) (Zingiberales:(More)
The effects of fenoxycarb, a Juvenile hormone analogue, at sublethal concentrations were tested on some biological parameters of Plutella xylostella (L.) in two consecutive generations. The calculated LC10, LC25, and LC50 values of the insecticide were 21.58, 43.25, and 93.62 mg/liter on third-instar larvae, respectively. Fenoxycarb significantly reduced(More)
The cucumber fly, Dacus ciliatus Loew., is a destructive pest of cucurbit crops in some regions of Iran. Susceptibility of adults of D. ciliatus 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,(More)
The diamondback moth, Plutella xylostella (Lepidoptera: Yponomeutidae), is a serious threat to Brassica vegetables in Iran, including Tehran province. The ovicidal effects of different classes of insecticides on P. xylostella were investigated, using three fixed doses (based on commercial formulations). At the lowest concentration (500 mg L-1), the(More)
