Efficiency of Coccinella undecimpunctata (Reiche) adults, in Suppressing Aphid gossypii (Glover) Population on Tomato Plant
نویسندگان
چکیده
Biological control is a very safe and effective method for the management of pests. In this study, Coccinella undecimpunctata (Reiche) adults were used in Aphid gossypii population. The total mean reduction percentage A. individuals recorded 67.8, 74.7 and 85.26 % at three different levels release treatment 1, 3 5 adult predators/plants respectively. Also, results showed that releasing C. undecimpunctataadult stage reduced damage caused by yield tomato plants. fruit weight fruit's number/ plant increased presence predators compared with control.

INSECTICIDE RESISTANCE IN THE COTTON APHID, Aphis gossypii GLOVER IN EGYPT
The cotton aphid, Aphis gossypii Glover (Hemiptera Aphididae), is one of the most important sap sucking pests in many cotton-growing areas world-wide. In this study, the efficacies of seven insecticides [organophosphate (Fenitrothion & Pirimiphos-methyl), carbamate (Carbosulfan & Aldicarb), pyrethroid (Lambda-Cyhalothrin & Deltamethrin) and imidaclopride (Confidor)] were determined against four...
متن کاملAn example of host plant expansion of host-specialized Aphis gossypii Glover in the field
The host plant expansion of host-specialized Aphis gossypii (Glover) has been well studied in the laboratory; however, this phenomenon is poorly understood in the field. Here, we provide a series of laboratory and field experiments to assess the role of zucchini in the host plant expansion of cotton-specialized aphids. We observed that cotton-specialized aphids possessed the ability to expand o...

BACKGROUND Pesticide resistance monitoring is a crucial part to achieving sustainable integrated pest management (IPM) in agricultural production systems. Monitoring of resistance in arthropod populations is initially performed by bioassay, a method that detects a phenotypic response to pesticides. Molecular diagnostic assays, offering speed and cost improvements, can be developed when the caus...
متن کاملThe joint action of destruxins and botanical insecticides (rotenone, azadirachtin and paeonolum) against the cotton aphid, Aphis gossypii Glover.
The joint action of destruxins and three botanical insecticides, rotenone (Rot), azadirachtin (Aza) and paeonolum (Pae) against the cotton aphid, Aphis gossypii, was bioassayed. In laboratory experiment, several synergistic groups of destruxins with botanical insecticides were found by means of Sun's Co-toxicity Coefficients (CTC) and Finney's Synergistic Coefficient (SC). The best synergistic ...
