The journal of Toxicology and pest control is one of the series issued twice by the Egyptian Academic Journal of Biological Sciences, and is devoted to publication of original papers related to the interaction between insects and their environment. The goal of the journal is to advance the scientific understanding of mechanisms of toxicity. Emphasis will be placed on toxic effects observed at relevant exposures, which have direct impact on safety evaluation and risk assessment. The journal therefore welcomes papers on biology ranging from molecular and cell biology, biochemistry and physiology to ecology and environment, also systematics, microbiology, toxicology, hydrobiology, radiobiology and biotechnology. www.eajbs.eg.net Provided for non-commercial research and education use.

Two programs for controlling the western flower thrips (WFT), Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), were evaluated. Greenhouse experiments were conducted for reducing F. occidentalis populations on pepper plants. The first program was by releasing four phytoseiid predacious mite species namely Neoseiulus arundonaxi (Metwally and Sanad), N. barkeri (Hughes), N. bicaudus (Wainstein), and Cydnoseius negevi (Swirski and Amitai) in the presence of blue sticky traps. The second one was by applying four sequential applications of different pesticides. Results showed that two releases of N. bicaudus, N. barkeri, and N. arundonaxi in the presence of the blue sticky traps reduced WFT population by 45 to 56%. The best control management of the WFT was by the following insecticides: chlorfenapyr, imidacloprid, azadirachtin, and agricultural potassium soap (third program).

Trials were conducted in a cotton field at Qaha Research Station, Qaluobia governorate, Egypt, to evaluate the dispersal ability and parasitism rate by the egg parasitoid Trichogramma evanescens West. (Hymenoptera: Trichogrammatidae), as well, to estimate the effect of parasitoid density from the releasing site on parasitism rate. Obtained data showed a limited dispersal ability for the parasitoid. The parasitism rates at 0, 50, 100, 150 and 200 cm. differed statistically from each other, being highest in the S. cerealella eggs placed at the shortest distance (43.03, 18.12, 10.92, 8.77 and 5.6%, respectively). The effect of releasing point and density on parasitism rate were also estimated. Increasing parasitoid density raised the rate of parasitism. When 2000, 3000 and 4000 parasitoids were released from the release point, the parasitism rates (mean percent ages for the whole 5 distances), were 33.21, 38.13 and 42.65%, respectively.
