Toxicological, biological and biochemical impacts of Indoxacarb and Methoxyfenozoid on the larvae of the Cotton leafworm, Spodoptera littoralis (Boisd.). (Lepidoptera: Noctuidae)

Abstract

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.

Insecticidal Activity of Pyriproxyfen, A Juvenoid, and Its Suppressive Effect on Growth and Development of The Black Cutworm, Agrotis ipsilon (Hufnagel) (Lepidoptera: Noctuidae)

“…Results of the present study were consistent with those reported results, since treatment of 4 th or 5 th instar larvae of A. ipsilon with a series of pyriproxyfen concentrations led to detrimentally suppressed pupation, proportional to the concentration. The present result was, also, in agreement with many reported results of reduced pupation of different insects, other than A. ipsilon, after treatment with various IGRs, such as such as P. xylostella after treatment with Hexaflumuron (Mahmoudvand et al, 2012); S. littoralis after treatment with novaluron (Ghoneim et al, 2015), cyromazine (Tanani et al, 2015), methoxyfenozide (Khaled and Farag, 2015) and cycloheximide (Basiouny and Ghoneim, 2018); G. Pyloalis after treatment with lufenuron (Aliabadiet al, 2016)and fenoxycarb (Singh and Tiwari, 2016); the whitefly parasitic wasp Encarsia formosa after treatment with pyriproxyfen and fenoxycarb (Wang and Liu, 2016); P. gossypiella after treatment with novaluron (Ghoneim et al, 2017a), teflubenzuron (Said et al, 2017), noviflumuron (Hamadah and Ghoneim, 2017) and diofenolan (Tanani and Bakr, 2018); P. unionalis after treatment with novaluron (Ghoneim et al, 2017b); M. stabulans after treatment with pyriproxyfen (Hamadah, 2018); etc.…”

“…Also, the present results were in accordance with many reported results of prolonged larval and pupal durations indicatingregressed developmental rate of other insects after treatment with IGRs of various categories, such as Cx. pipiens after treatment with kinoprene (Hamaidia and Soltani, 2014) and methoxyfenozide (Hamaidia and Soltani, 2016); the diamondback moth Plutella xylostella after treatment with Pyriproxyfen (Mahmoudvand et al, 2015); S. littoralis after treatment with diflubenzuron (Aref et al, 2010), Lufenuron (Gaaboub et al, 2012), novaluron (Ghoneim et al, 2015), methoxyfenozide (Khaled and Farag, 2015) and cyromazine (Tanani et al, 2015); G. pyloalis after treatment with lufenuron (Aliabadi et al, 2016); C. cephalonica after treatment with methoprene (Tripathi and Tiwari, 2006) and fenoxycarb (Begum and Qamar, 2016); P. gossypiella after treatment with buprofezin (Al-Kazafy, 2013), teflubenzuron (El-Khayat et al, 2015;Said et al, 2017), chromafenozide (Salem, 2015), pyriproxyfen (Sabry and Abdou, 2016), novaluron (Hamadah and Ghoneim, 2017;Ghoneimet al, 2017a) and diofenolan (Tanani and Bakr, 2018); the false stable fly Muscina stabulans after topical application of pyriproxyfen onto the early last (3 rd ) instar larvae (Hamadah, 2018); H. armigera after feeding on diet mixed with hexaflumuron, lufenuron or chlorfluazuron (Khorshidi et al, 2019); etc.…”

The disruptive impact of novaluron, a chitin synthesis inhibitor, on the adult performance and reproduction of the black cutworm, Agrotis ipsilon (Hufnagel) (Lepidoptera: Noctuidae)

“…Also, the present results were in accordance with many reported results of partiallyor completely blocked adult emergence of insects other than A. ipsilon after larval treatment with different IGRs, such as the diamondback moth Plutella xylostella after treatment with hexaflumuron (Mahmoudvand et al, 2012); the Egyptian cotton leafworm Spodoptera littoralis after treatment with novaluron (Ghoneim et al, 2015), cyromazine (Tanani et al, 2015), methoxyfenozide (Khaled and Farag, 2015) and cycloheximide (Basiouny and Ghoneim, 2018); the vinegar fly Drosophila melanogaster after topical application of 3 rd instar larvae with pyriproxyfen (Benseba et al, 2015); the lesser mulberry snout moth…”
