“…Multiple doses of neem extract confirmed the damage to both parameters. A similar finding on the reduction of weight in insects treated with neem extract was observed in D. abbreviatus larvae (Weathersbee III and Tang 2002), when mixing neem extract with larval food.…”

“…In our study, the survival rates of adult M. domestica were barely observed in the first 3 weeks, but they, including the control flies, abruptly decreased at the beginning of the fourth week. Flies in the treated groups exhibited lower survival rates than those in the control group, in which mortality may be due to natural factors that are similar in other experiments (Weathersbee III and Tang 2002). When the neem extract was provided with the larval diet, we observed a significant reduction in pupal weight and adult wing length in both C. megacephala and M. domestica, which indicated the smaller size of adult obtained.…”

“…Example of this include: reduction of fecundity and post-embryonic development in the melonfly, Bactocera cucurbitae (Coq. ), oriental fruit fly, Bactocera dorsalis (Hendel) (Singh 2003), and root weevil, Diaprepes abbreviatus (L.) (Weathersbee III and Tang 2002); fecundity and longevity of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Steffens and Schmutterer 1982;Di Ilio et al 1999) and the bug, Clavigralla scutellaris Westwood (Mitchell et al 2004); delay of growth development in the moth, Helicoverpa armigera (Hübner) (Ma et al 2000); inhibition of feeding in the mosquitoes, Culex tarsalis Coquillett and Culex quinquefasciatus Say (Su and Mulla 1998a); ovicidal activity in the mosquitoes, C. tarsalis and C. quinquefasciatus (Su and Mulla 1998b); inhibition of oviposition in the mosquitoes, Anopheles stephensi Liston and Anopheles culicifacies Giles (Dhar et al 1996); larvicidal activity in the horn fly, Haematobia irritans (L.), stable fly, Stomoxys calcitrans (L.), and housefly (Miller and Chamberlain 1989); and repellency effect in the sand flies, Phlebotomus papatasi (Scopoli) (Dhiman and Sharma 1994) and Phlebotomus argentipes Annandale and Brunetti (Sharma and Dhiman 1993), and mosquito, A. culicifacies , which was also reviewed by Mulla and Su (1999). Despite the results just listed, probability of insect to product effect from A. indica is low (Vollinger and Schmutterer 2002).…”

Efficacy of neem extract against the blowfly and housefly

et al. 2008

The blowfly, Chrysomya megacephala (Fabricius), and housefly, Musca domestica Linnaeus, are ubiquitous insects that have the potential to spread a variety of pathogens to humans and livestock. Pest management techniques for populations of these flies are needed. Currently, bioinsecticides, particularly those derived from plant origin, have been increasingly evaluated in controlling populations of medically important insects. In this study, an attempt was made to evaluate the efficacy and biological activity of a commercially available neem extract, containing 0.24% azadirachtin A, against C. megacephala and M. domesitca. Laboratory bioassays were performed using the feeding method of mixing neem solutions with fresh beef, once or multiple times, as food for rearing third instar. The laboratory tests showed that neem products significantly reduced larval and pupal survival, adult emergence, pupal weight, adult wing length, and fecundity on the subsequent generation, in a dose-dependent manner in both species. Efficacy was observed in the first generation and could extend to the second generation. Despite these reductions, reduction in total adult longevity was not evident for larvae fed once on neem solutions with fresh beef, and slightly earlier (approximately 1 week) mortality was observed in both species when they were fed as larvae on multiple doses. Adverse effects of this neem-based product toward M. domestica were slightly greater than those in C. megacephala. These data reinforced the efficacy of neem extract in reduced adult emergence and anti-fecundity in the subsequent generation. However, neem extract induced only low to moderate larval and pupal mortalities.

“…The search for effective bio-control methods for wood preservation is continuing but one that could be useful is the natural insect growth regulator, azadirachtin (AZA). This botanical compound can be effective yet it is biodegradable and rapidly metabolizes in the environment (Weathersbee and Tang 2002). AZA can be extracted from the seeds of Azadirachta indica i.e.…”

Termites are one of the major wood destroying agents in the tropics and with the increasing rate of deforestation, there is a need to protect wood from biodegradation in order to extend its service life. In this study the incidence and severity of termite attack on Eucalyptus grandis sapwood treated with CCA, used engine oil and neem extract were investigated. Sixty samples (20 × 20 × 300mm) were prepared from the sapwood at mid-height of the tree of E. grandis and air seasoned for two weeks then treated with the preservatives. An area of 20m by 20m in a pine plantation and 15 plots of 1m by 1m were selected at random. Four samples, one from each treatment, were placed at the corners of the selected plots.Inspection and evaluation of stakes was made by visual assessments after every 30 days for any sign of termite attack for a period of 8 months. The specimens were removed from the ground, damage assessed and returned to the ground. After 4 weeks all the untreated wood samples had been attacked, neem extract treated wood samples were attacked after 17 weeks and used engine oil treated samples after 30 weeks. None of the CCA treated wood samples were attacked by the end of study period. Chi square analysis showed a high association between treatment and incidence as well as between treatment and severity. It was recommended that further research be carried out on neem extract using different concentrations.

Using insect repellent compounds, especially during the warm months, provides comfort for people and prevents spreading of the insect-borne diseases such as dengue fever, malaria and Leishmaniasis. Poisons derived from plants contain alkaloids, glucoside and some essential oils that are taken from plant tissues. They may have repellent and insecticide properties with little toxicity to humans and animals. In this study, Neem plant 1 from Bandar Abbas city was used to assess its repellency effect. Therefore, after drying and powdering using maceration method, final Neem extract concentration of 5%, 10% and 20% was provided. Mittler & Dadd methodology was hired to assess this effect. In this method, the antifeedant effect of the Neem plant extract was evaluated on cabbage-feeding aphid (Brevicoryne brassicae). After 24 and 48 hours, the reduced numbers of feces spot of aphids showed that the ingestion of the provided food mixture contained Neem plant extract was significantly decreased. Here it was shown that the Neem plant extract could be used as an efficient repellent.
