In a search for natural products that could be used to control the vectors of tropical diseases, four medicinal plants grown in Nigeria; Moringa oleifera, Senna alata, Caesalpinia pulcherrima, and Vernonia amygdalina were screened for molluscicidal effects. Serial dilutions of 1000, 625, 500, 375, 250, and 125ppm were prepared from the stock solution of the extracts. Adult Biomphalaria pfeiffer...

The objective of this study was to evaluate the larvicidal activity of diterpenoids obtained from the oil-resin of Copaifera reticulata against Aedes aegypti larvae, the principal vector of dengue and urban yellow fever. Four diterpenes were obtained from oil-resin extraction with organic solvents and subsequent chromatographic and spectroscopic procedures allowed to isolation and identificatio...

The use of synthetic larvicides to control vector populations is detrimental to human and environmental health and selects for insecticide resistance. Plants can be alternative sources of effective and safe mosquito control agents. In the present work the chemical composition and larvicidal activity, of essential oil of Lavandula stoechas (lamiaceae), growing in wilds of Morocco, against the ma...

Southern root-knot nematode (Meloidogyne incognita) is an obligate, sedentary endoparasite of more than 3000 plant species, that causes heavy economic losses and limit the development of protected agriculture of China. As a biological pesticide, emamectin benzoate has effectively prevented lepidopteran pests; however, its efficacy to control M. incognita remains unknown. The purpose of the pres...

A marine-derived red alga, along with their active constituents, were actively screened for biocontrol potential against major insect pests. The current study explored the larvicidal activity of crude methanolic extracts alga Halymenia dilatata (Mx-Hd) Aedes aegypti (Linn.), and enzyme inhibition, repellent activity, non-target toxicity was species. Mx-Hd to exposed larvae dose-dependent, it si...

Grape berry moth is a major pest of vineyards across eastern North America. Increasing infestations in Michigan commercial under active management have raised concerns about insecticide resistance this species. We tested the susceptibility male moths from 5 southwestern over 2 years using range concentrations, followed by probit analysis resulting mortality data. In 2021 and 2022, topical appli...

Leaf-cutting ants stand out among the main pests of agricultural and forestry crops. Chemical control is most used method to these insect pests, requiring development techniques that are less harmful environment. The present study aimed at verifying action Beauveria bassiana (Bals.) Vuill, Cordyceps fumosorosea (Wize), Metarhizium anisopliae (Metsch.) Sorokin isolates on in vitro mortality Acro...

accumulations of large quantities of wastes (manure, used litter, dead birds) which are excellent medium for fly-larvae over poultry houses provide breeding places for different groups of fly pests, with house-flies being the dominant species. this project is a comparative lab study. in this research project the larvicidal effects of cyromazine and triflumuron were studied as two insect growth ...

Several species of the family Apiaceae are aromatic herbs that produce essential oils usable on an industrial scale for pharmaceutical, cosmetic, and food purposes. In particular, some oils, such as green insecticides example, may replace synthetic insecticides, keeping most their efficacy avoiding environmental pollution or human poisoning. present study, we explored insecticidal potential Rid...

The Pink Bollworm Pectinophora gossypiella (Saunders) is a devastating pest in Egyptian cotton field. Insecticide control failure may be happen due to its biological features of hide inside bolls and rarely exposed insecticide application. Thus, bulk infested with larvae collected from fields Sharkia Benysuef governorate. Moreover, py, Op sub lethal concentrations laboratory bioassay. Toxicity ...
