background : within the framework to control mosquitoes, ovicidal, larvicidal and pupicidal activity of annona senegalensis leaf extract and its 4 fractions against anopheles gambiae and culex quinquefasciatus were evaluated in the laboratory conditions. methods : ovicidal test was performed by submitting at least 100 eggs of mosquitoes to 125, 250, 500, 1000 and 2000 ppm concentrations, while ...

The objective of this work was to evaluate the effect hexane fraction crude extract fruits and seeds Ricinus communis (HFFSRC) on eggs Spodoptera cosmioides frugiperda caterpillars eridania, S. frugiperda, cosmioides, under laboratory conditions through topical application ingestion, as well identify compounds in high-performance chromatography (HPLC-ESI-Q-TOF-MS/MS). To do so, three bioassays ...

INTRODUCTION Toxocara canis is an ascarid parasite of the small intestine of dogs that causes visceral larva migrans in humans. METHODS With the aim of demonstrating the effectiveness of the fungus Pochonia chlamydosporia on Toxocara canis eggs under laboratory conditions, a trial was set up in Petri dishes with 2% agar-water. RESULTS There was ovicidal activity of 43.8% (p < 0.01) in the t...

The objective was to evaluate the insecticidal effect of extracts Ziziphus joazeiro Mart., Croton sonderianus and Amburana cearenses on hatchability eggs fall armyworm Spodoptera frugiperda J. E. Smith (Lepidoptera: Noctuidae). three plant species were produced at concentrations 5%, 10% 15%, distilled water as a control. For each concentration, paper towel discs containing 30 immersed for secon...

Introduction: The nematophagus fungi have been suggested as an alternative way to eliminate the zoonotic helminths eggs from the environment. In the present study, we evaluated the ovicidal activity of a fungus, Paecilomyces lilacinus, recovered from a compost soil, on the eggs of parasitic helminths under in vitro condition. Methods: Water suspension of the soil samples collected from differen...
