The ram's horn snail (Planorbella trivolvis (Say)) is an intermediate host for a digenetic trematode (Bolbophorus confusus (Krause) Dubois) that has recently been discovered to be a significant problem in commercial channel catfish (Ictalurus punctatus Raf) production ponds in the Mississippi Delta region in the USA. In these catfish ponds, the digenetic life cycle of this parasitic trematode i...

Abstract Background The negative effect of over-reliance on the use synthetic pesticides have led to search for natural alternatives pest control. This study was designed evaluate toxicity crude plant extracts Jatropha ( curcas Linn.) seeds in comparison with methomyl some histopathological changes terrestrial snail species Monacha obstructa (Pfeiffer, 1842). and ethanol acetone were determined...

Restrictions on the use of synthetic molluscicides highlight importance developing alternative control methods. Nevertheless, biocontrol agents can be costlier and less effective than counterparts. One means increasing efficacy population suppression is to combine inundative biological with habitat management reduce growth target pests. Vineyards in cool, wet climate western England suffer from...

The pesticides belong to a category of chemicals used worldwide as herbicides, insecticides, fungicides, rodenticides, molluscicides, nematicides, and plant growth regulators in order to control weeds, pests and diseases in crops as well as for health care of humans and animals. The positive aspect of application of pesticides renders enhanced crop/food productivity and drastic reduction of vec...

Schistosoma haematobium and Schistosoma mansoni are prevalent in Zimbabwe to levels that make schistosomiasis a public health problem. Following three national surveys to map the disease prevalence, a national policy on control of schistosomiasis and soil transmitted helminths is being developed. This paper reviews the experiences that Zimbabwe has in the area of schistosomiasis control with a ...
