Bats, like many other small endotherms, often use facultative reductions in metabolic rate and body temperature (Tb) to decrease their daily energy expenditure (Lyman 1970). The lower energy requirements associated with heterothermy offset the high m

The social structure of banana bats (Neoromicia nanus) was studied in relation to reproductive events over an annual cycle in banana plantations in Mpumalanga Province, South Africa. Banana plantations were visited at monthly periods over a year, and

The 2 cryptic species of multimammate mice that occur widely in South Africa were, for many decades, lumped in a single species Mastomys natalensis sensu lato. This taxon was intensively studied because these rodents play a role in the epidemiology o

An artificial soil test was used to determine the LC50 values of carbaryl, chlorpyrifos, imidacloprid, cyfluthrin and fipronil against earthworms of the Pheretima group. For a 24-h interval, carbaryl was the most toxic to earthworms (LC50 = 77 mg kg

An artificial soil test was used to assess the toxicity of five insecticides, used for turfgrass pest management, to earthworms of the Pheretima group (Megascolecidae). The effects of cyfluthrin, carbaryl, chlorpyrifos, fipronil and imidacloprid on e

The effects of the chitin synthesis inhibitor lufenuron against potato tuber moth, Phthorimaea operculella (Zeller), eggs were determined by topically exposing different age groups of eggs (1-4 d old) to treated potato tubers (Solanum tuberosum L.) u
