Abstract

Different chemical and non-chemical treatments were evaluated for their influence against nymphs and adult females of Phenacoccus solenopsis on cotton leaves under laboratory conditions in El-Mattana Agricultural Research Station, Luxor Governorate in 20^th August, 2018. Three insect insecticides: Mospilan, Malatox and Admiral, bio-insecticide (Biover), mineral oil (KZ- oil) and plant oil (sesame oil) were used. The method of dipping was used throughout the present investigation. The obtained results revealed that the tested chemical and non-chemical treatments on P. solenopsis were varied under laboratory conditions. Also, these compounds gave the same efficacy against both the nymphs and adult females. But, the nymphs of P. solenopsis were more susceptible to the tested chemicals than the adult females. As well as, the insecticidal efficiency of Mospilan and Malatox showed the highest toxic against nymphs and adult females of mealybug on cotton leaves, while the plant oil (sesame) showed the lowest effect.

 

Key words: Phenacoccus solenopsis, effectiveness, insecticides, insect growth regulators, plant oils and cotton.
