Vector control is facing a threat due to the emergence of resistance synthetic insecticides. Insecticides botanical origin may serve as suitable alternative biocontrol techniques in future. Garlic bulbs are common and widely distributed many parts of Nigeria with medicinal properties, but larvicidal activity this plant has not been reported so far. Ethanol extract of Allium sativum (garlic bulb) was evaluated for activities against filarial mosquito Culex quinquefasciatus. The larval...

Bivalve mollusks represent a nutritious source with low environmental impact; as result, they are one of the most attractive aquaculture options. Advances in microencapsulation technology offer great potential to face key bivalve nutrition problems, and an alga-based microencapsulated diet can turn enriched bivalves into functional foods. The central goal this study was evaluation food intake function particle size microalga content following supply four diets, incorporating core material...

The corrosion of mild steel (uncoated), galvanized and stainless (304L) have been studied using the weight loss method over a period 98 days with measurements made at 14 days' interval inground melon (locally called egusi), cassava pulp, mashed palm fruit, tomato black-eyed bean pulp respectively. results obtained show that average rates 304 steel, are in ground (1.98 x 10-3, 1.81 10-2, 2.65 10-2) mpy; (3.68 7.09 10-1, 5.64 10-1) palm-fruit (4.75 2.38 2.83 x10-3) mpy ; (3.07 9.25 1.16) (5.46...

Chlorpyrifos, an organophosphate insecticide widely used to control agricultural pests, poses a significant environmental threat due its toxicity and persistence in soil water. Our work aimed evaluate the acute (survival) chronic (regeneration, locomotion, reproduction) of chlorpyrifos non-target freshwater planarian Girardia tigrina. The 48 h lethal concentration (LC50) commercial formulation, containing 480 g L−1 chlorpyrifos, active ingredient, was determined be 622.8 µg a.i. for...
