Abstract:

 Chemical control is the mainly control method for Plutella xylostella (L.) throughout the world. Choosing insecticides with high efficacy on all stages of this pest can help us control it well. In this case, toxicities of indoxacarb and hexaflumuron on eggs, larvae and adults of P. xylostella were studied with leaf dip method. The LC50 values of egg stage for indoxacarb and hexaflumuron were 201.40 and 37.32 mg/L, respectively. Also indoxacarb and hexaflumuron had excellent toxicity on the 3rd larval instar (LC50: indoxacarb=4.82 mg/L, hexaflumuron=1.48 mg/L). Results of moth toxicity indicated that above insecticides had no acceptable toxicity on this insect (LC50: indoxacarb=845.20 mg/L, hexaflumuron=3 438 mg/L). According to the calculated LC50 values, hexaflumuron was more toxic than indoxacarb to eggs and larvae of diamondback moth but at the adult stage the indoxacarb was more toxic.

Key words: Diamondback moth, toxicity, indoxacarb, hexaflumuro
