Effects of a methanolic extract of the plant Haplophyllum tuberculatum and of teflubenzuron on female reproduction in the migratory locust, Locusta migratoria (Orthoptera: Oedipodinae)

Effect of a selected rice bran extract and a chitin synthesis inhibitor on viability of eggs of the house fly Musca domestica Linnaeus.

“…Findings of the present study indicate that feeding vitellogenic Musca domestica females on different concentrations of ethanolic and acetonic extract of rice bran, Oryza sativa has a significant effect on viability of laid eggs. Similar results were recorded, using different plant extracts for different insect species; Fertility of Locusta migratoria were reduced after treatment of newly emerged females with methanolic extract of leaves and stems of Haplophyllum tuberculatum (Acheuk et al 2012). The number of eggs laid per female and egg viability of Spodoptera littoralis was reduced after treatment with 2% suspension of ground seed of A. indica (El-sayed, 1982).…”

Phytochemical Study and Bioinsecticidal Effect of the Crude Ethonolic Extract of the Algerian Plant Artemisia Judaica L. (Asteraceae) Against the Black Bean Aphid, Aphis Fabae Scop.

“…Many researchers have reported on the effectiveness of plant extracts against insects (Acheuk et al, 2012;Abdellaoui et al, 2013Abdellaoui et al, , 2016Pavela,2004 andNathan et al, 2006). In the present work, the crude ethanolic extract of A. judaica showed potent insecticidal effects against the black aphid, A.fabae.…”

“…This toxic effect of the extract might be due to the various bioactives compounds that exist in the aerial part of the plant. Indeed, the crude extract of plant is a mixture of potentially bioactive substances which may act synergically (Acheuk et al, 2012) or independently (Kabir, 2013). Previous studies demonstrated the insecticidal effects of Artemisia plant extracts against other insects pest.…”

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

“…Reduction in fecundity noticed in this study was also reported by several investigators (Pineda et al, 2007;Rastegari and Subrahmanyam, 2008;Pineda et al, 2009;Enriquez et al, 2010;Shahout et al, 2011;and Zarate et al, 2011) on Spodoptera species. Acheuk et al, 2012 suggested moreover, that chitin deficiency weakened the exoskeleton and muscle attachment in the embryo, rendered it incapable of withstanding the strong pressure required for successful hatching, thus reduced hatching of eggs laid by treated females. Activity determination of various enzymes in haemolymph of treated and untreated 6 th instar larvae of S.…”
