Susceptibility to Acaricides of the Mite Tetranychus cinnabarinus Infesting Cotton in Egypt12

Toxicity and Biological Activity of Five Plant Extracts to the Two-Spotted Spider Mite, Teteunychus urticae and Predatory Mite, Amblyseius swirskii (Tetranychidae: Phlytoseiidea

“…4. Toxicity tests and preparation of concentratemortality lines of tested plant extracts: The leaf-spray method (El-Defrawi et al, 1965 and Abo-Shabana, 1980) was applied to test the susceptibility of field strain of T. urticae and A. swirskii to five different plant extracts compared with susceptible strain. Four castor-oil bean leaf discs (2 cm diameter) were placed on moist cotton pad in Petri dish (9 cm in diameter) which represents as four replicates for each concentration of different plant extracts.…”
