“…The present results are in conformity with several authors (Schmutterer & Freres, 1990;Nicol & Schmutterer, 1991;Wilps et al, 1992;Nicol et al 1993;Mohamed & El-Gammal, 2002;Mohamed et al, 2006 andGhazawy et al, 2010). They reported that treatment of S. gregaria with neem plant extracts caused high mortality which often occurred during moults, prolonged nymphal development and disturbance of metamorphosis, the latter resulted in morphogenetic defects of eyes, antennae, legs and wings.…”

“…Three proteins bands normally absent were expressed in fenoxycarb-treated embryos (Kelly and Huebner 1987). In Schistocerca gregaria, new protein bands appeared and others disappeared during embryogenesis in treated eggs with azadirachtin compared to the control group (Ghazawy et al, 2010). Also Guneidy et al (2011) explained that treatment with lufenuron and waste product rice bran extract against Musca domestica during embryogenesis resulted in the appearance and disappearance of certain protein fractions.…”

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

“…Azadirachtin was also shown to be harmless to the survival of predatory bug, O. laevigatus (Biondi et al 2012). Azadirachtin-based products act by inhibiting the production of juvenile hormones and ecdysone; these compounds are responsible for insect growth and may cause high mortality rates when applied to immature insects (Ghazawy et al 2010). Therefore, we speculate that azadirachtin showed a high selectivity ratio because it functions to disrupt molting, which was not a factor in our experiments using adult C. lividipennis.…”

Selectivity and sublethal effects of some frequently-used biopesticides on the predator Cyrtorhinus lividipennis Reuter (Hemiptera: Miridae)

The green miridbug, Cyrtorhinus lividipennis, is an important predator of the rice brown planthopper, Nilaparvata lugens. In this study, the selective toxicity of seven commercial biopesticides for C. lividipennis was examined under laboratory conditions; abamectin was the most selective to C. lividipennis, followed by matrine and azadirachtin. Veratridine, rotenone, Bacillus thuringiensis and Beauveria bassiana showed less selectivity for C. lividipennis. Subsequently, matrine, abamectin and azadirachtin were selected for sublethal assessments with respect to C. lividipennis due to their high toxicities to N. lugens. C. lividipennis treated with sublethal concentrations (LC 10 and LC 20) of the three biopesticides could distinguish volatiles released from healthy and N. lugens-infested plants indicating that the biopesticides tested did not affect the foraging ability of surviving miridbugs. Azadirachtin decreased the consumption capability of C. lividipennis when the densities of N. lugens were 20, 30, 40 and 50 insects per vial. Sublethal concentration treatment did not impact the pre-oviposition period or egg hatchability of C. lividipennis. However, the fecundity of C. lividipennis exposed to azadirachtin and abamectin increased by 27-41% compared to the untreated individuals. In summary, abamectin or matrine together with C. lividipennis could be considered an effective, sustainable pest management strategy for rice.

“…Al-Fifi (2009) tested various Neem products against resting and flying S. gregaria the treatment during flight activity caused, for all products applied an increase of the mortality rate, except the Neem oil enriched and pure Neem oil of Giessen, up to 70 and 90% respectively. Ghazawy, et al (2010) concluded that after suitable field trials, the use of azadirachtin may be a viable alternative to chemical insecticides for control of grasshoppers in Egypt. Abdel-Fattah, et al (2012) revealed that the fungus M. anisopliae var.…”

The effect of Metarhizium anisopliae var. acridum, anti-feedant agent (azadirachtin), anti-molting agent (Flufenoxuron), Juvenile hormone analogue compound (pyripoxyfen) and Chloropyrifos (two formulations) was evaluated under field conditions of Shark El-Uwainat area against the nymphal instars 3 rd , 4 th and 5 th of Locusta migratoria migratorioides. The obtained results revealed that the integration between M. anisopliae and 20% of the recommended dose of all the compounds exhibited the highest integral action, recording 100% population reduction after (11-13days) of application. On the other hand, the fungus alone induced moderate percentages of population reduction after 10 days of treatment. Also, on comparing the dose and half the dose of the fungus the full dose gave approximately the same trend of activity. Green muscle (M. anisopliae), antifeedant agent, anti-molting agent and juvenile hormone analogues compound can be useful for proposed different elements of an IPM strategy.
