Highlights
The introduction of pesticides in pest management by agriculturalists is very vital for increase food production
The results of acute toxicity study indicate concentration and duration dependent mortality of Bufo regularis tadpoles exposed to butaforce and termex pesticides respectively
After 96h exposure to 0.35 and 0.75mg/L concentrations of butaforce, 33% and 100% mortality of Bufo regularis tadpoles were recorded while 14% and 100% mortality were observed in tadpoles exposed to 0.7 and 1.68mg/L concentrations of Termex (Table 1)
Summary
The introduction of pesticides in pest management by agriculturalists is very vital for increase food production This benefit is not without negative impact on the ecological system especially aquatic habitat as studies have shown that 99% of applied pesticides go into the air, water and soil and only 1% reach the target organism [1]. Studies have shown decline in amphibian population due to pollution, disease outbreak and climate change [3] Pesticides from agricultural run-offs impair the normal balance of the flora and fauna of the aquatic ecosystem [4]. Bufo regularis tadpoles play an important role in aquatic ecosystem. There is the need to investigate the effects of butaforce and termex pesticides on aquatic organisms such as Bufo regularis tadpoles. The present study was desinged to determine the cumulative mortality, median lethal concentration (LC50), safe level, no observe effect concentration (NOEC), lowest observed effect concentration (LOEC) and the maximum allowable concentration (MAC) of butaforce and termex pesticides on Bufo regularis tadpoles
