Effects of a Neem Compound on the Fecundity and Longevity of Ceratitis capitata (Diptera: Tephritidae)

Efficacy of neem extract against the blowfly and housefly

“…in C. megacephala. This finding was in accordance with the data of Di Ilio et al (1999), which showed that the longevity of C. capitata was slightly decreased after exposure to neem compound. 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.…”

“…The work published by Khan et al (2007) microscopically demonstrated that the decrease in fecundity of B. cucurbitae and B. dorsalis exposed to neem compound was due to the block of ovarian development. Likewise, mixing of a commercial formulation of neem in the adult diet caused reduction in the fecundity of C. capitata by interfering with oogenesis (Di Ilio et al 1999). The block in the ovarian activity of C. capitata, resulting from neem compound, was verified by histological observation (Di Ilio et al 1999).…”

“…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).…”

Enhanced Toxicity of Bacillus thuringiensis Subspecies kurstaki and aizawai to Black Cutworm Larvae (Lepidoptera: Noctuidae) With Bacillus sp. NFD2 and Pseudomonas sp. FNFD1

“…Azadirachtin, a tetranortriterpenoid compound derived from the neem tree, Azadirachta indica A. Juss (Sapindales: Meliaceae), has insecticidal activity against phytophagous insects (Spollen and Isman 1996). This active compound has several biological properties, including antifeedant effects (Zehnder and Warthen 1988;Schmutterer 1990), insect growth regulator characteristics (Ilio et al 1999), and repellency (Schmutterer 1990). …”

Mecanización de métodos de control de Ceratitis capitata (Wiedemann) en cítricos.

“…Presenta baja toxicidad para mamíferos y es relativamente seguro para los insectos beneficiosos (Gandhi et al, 1988;Schmutterer, 1990). Estudios sobre los efectos de la azadiractina en la fecundidad y longevidad de C. capitata han mostrado una elevada capacidad esterilizante del producto (Di Ilio et al, 1999). No obstante, presenta el inconveniente de que se degrada rápidamente con la radiación UV (Barnby et al, 1989).…”
