The objective of this study was to use chlamydospores of the fungus Pochonia chlamydosporia (isolates VC1 and VC4) against Toxocara canis eggs in a 15-day in vitro assay. One thousand T. canis eggs were placed in Petri dishes containing 2% water agar medium with different concentrations of chlamydospores (1,000, 10,000 or 100,000) of each fungal isolate of P. chlamydosporia (treated groups) and...

Impact of brown seaweed, Padina pavonica (Linn.) chloroform, and benzene extracts were evaluated against an economically important cotton pest, Dysdercus cingulatus (Fab.) (Pyrrhocoridae). The result reveled that between the two solvents, benzene extracts of P. pavonica caused more nymphal mortality. It reduce D. cingulatus egg hatchability than chloroform extract. Benzene extract also reduced ...

Background: Data on ovicidal activity of pediculicides are essential to determine the efficacy of commercial products, and to define application schemes. We present an adaptation of historical methods for rearing head lice, and describe their development ex vivo. Methods: Adult head lice were collected and fed on volunteers to obtain fertile eggs of known age. Two methods of feeding were applie...

Coumarin is a phenolic compound that mainly affects the liver due to its metabolization into a toxic compound. The deterrent and ovicidal activities of coumarin in insect models such as Drosophila melanogaster have been reported. Here we explore the molecular mechanisms by which these insects protect themselves and their eggs from this toxic plant metabolite. Coumarin was fatal to the flies in ...

The in vitro anthelmintic effect of the extracts on Haemonchus contortus (H. contortus) three forage species tropical dry forest is known; however, there no information about effects extract partitions, nor their chemical composition. objectives this study were to evaluate ovicidal activity H. partitions Gliricidia sepium, Leucaena leucocephala, and Pithecellobium dulce, identify compounds pres...

Mosquitoes contribute to main disease burden in India as they are causative agent of many vector-borne diseases. Various methods now being used control the vectors that might help stop spread. In this regard, current study was carried out analyze phytochemicals, ovicidal and repellent activities acetone, chloroform ethanol extracts Sphaeranthus indicus leaves Caesalpinia pulcherrima against vec...
