The two-spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae) is a cosmopolitan pest that causes considerable damage to vegetables, fruit and flower plants. acaricidal, ovicidal repellent activity of four different extracts Aloe vera L. (Asphodelaceae) leaves were evaluated against T. under laboratory conditions. Four solvents A. leaf tested at concentrations 0.25, 0.50, 1.0 2.0%...
Biological control is considered one of the most used alternative measures to combat helminths relevance in veterinary medicine and public health. Among these parasites, Toxocara canis stands out for its high prevalence worldwide distribution, addition being main cause visceral larva migrans man. The present work aimed fungus Pochonia chlamydosporia (isolate Pc-10) on eggs T. canis. In order do...
The insect growth regulator, Fenoxycarb, induced various morphogenetic aberrations in Notonecta unifasciata, Anax junius and Pantala hymenaea after treatment of late nymphal stages. Most affected nymphs died while molting from nymphs to adults. Fenoxycarb is also ovicidal to young eggs of N. unifasciata. The treatment rate of 0.034 kg AI/ha fenoxycarb induced some reduction in N. unifasciata po...
The anthelmintic effect of acetone leaf extract and fractions of Anogeissus leiocarpus was investigated to determine the relative efficacy of the components as anthelmintic against Haemonchus contortus (Rudolphi). The fractions were obtained by solvent-solvent group separation of the leaf extract. The fractions were evaluated for ovicidal and larvicidal activity by egg hatch inhibition assay an...
Fraxinellone, a well-known and significant naturally occurring compound isolated from Meliaceae and Rutaceae spp. has been widely used as a drug for the treatment of tumors. On the other hand, fraxinellone exhibited a variety of insecticidal activities including feeding-deterrent activity, inhibition of growth, and larvicidal activity. The present study focused on the antifeedant and larvicidal...
Laboratory and extended laboratory bioassays were conducted to determine the residual toxicities of various insecticides against two key pests of cranberries, Sparganothis sulfureana and Choristoneura parallela (Lepidoptera: Tortricidae), and their non-target effects on the predatory Orius insidiosus (Hemiptera: Anthocoridae). The effects of nine insecticides with different modes of action on S...
4-Methyl-7-hydroxy coumarin is considered as a lead molecule as a biopesticide. Its mono bromo and tribromo derivatives were synthesized. Two more derivatives were synthesized by acylation. Compound 1 (3,6,8-tribromo-7-hydroxy-4-methyl-chromen-2-one) was found to be the most potent against IVth instar larvae of C. quinquefasciatus and A. aegypti the LC50 being 1.49 and 2.23 ppm respectively. It...
Mosquitocidal activities of Lavandula angustifolia (L. angustifolia) different concentration essential oil (EO) and its major phytocompounds (MPCs) tested against three important human vector mosquitoes (HVMs). The quantitative analyses EO phyto-chemical compositions (PCCs) were analyzed by using Gas Chromatography-Mass Spectrometry (GC-MS). HVMswere exposed to various concentrations MPC...
