Abstract The harlequin ladybird, Harmonia axyridis (Pallas, 1773), is native to Asia but has been introduced many countries, both intentionally and unintentionally. In the Middle East region, H. was so far only known from Iran Turkey. This study reports for first time a country with hot desert climate, Saudi Arabia. single specimen that found most likely result of unintentional release. Successful spreading in Arabia will be limited because high temperatures during summer scarcity prey...
A combination of bioassay and biochemical approaches were used to determine toxicity Artemisia annua essential oil (AaEO) Pseudococcus viburni. AaEO via leaf dipping showed LC50 values 0.693 0.419% after two time exposures. Different concentrations caused deterrence index between 28.58 86.26% by the calculated ED50 0.4%. Although, α-esterase activity using α-naphtyl acetate increased in treated nymphs 24 hours but it lower β-naphtyl acetate. Glutathione S-transferase assayed CDNB higher than...
Development and demography of Adalia decempunctata L. were studied under laboratory conditions at seven constant temperatures (12, 16, 20, 24, 28, 32 36°C).First instar larvae failed to develop second 12°С no development occurred 36°C.The total developmental time varied from 47.92 days 16°C 15.94 28°C increased 32°C.The lower temperature thresholds 11.05 9.90°C, thermal constants 290.84 day-degree 326.34 estimated by traditional Ikemoto-Takai linear models, respectively.The threshold (T min...
Adalia decempunctata (L.) is a common predator in agroecosystems and the natural environment. Its biology life table were studied nymph/adult hosts of Aphis gossypii Glover, fabae Scop. on eggs Ephestia kuehniella Zeller. Raw data all individuals A. analyzed using age-stage, two-sex, life-table theory. The results this study indicate shortest immature developmental period (IDP) feeding E. (18.33 days) longest (21.82 days). longevity was, however, after gossypii. fecundity rate females was...
Toxicity and physiological alterations were determined in Pseudococcus viburni nymphs treated with Artemisia annua methanolic extract.The leaf dipping bioassay showed LC 50 values of 0.287% 0.194% 24 48 hours post-exposure.Activities general esterases significantly higher the control than those which had been except for h time interval using α-naphtyl acetate.The activity glutathione S-transferase CDNB (1-chloro-2,4-dinitrobenzene) nymphs, was at both intervals while no significant...
