Some aspects of the biology of the maize stalk borer Busseola fusca fuller (Noctuidae: Lepidoptera) in Kenya
Pupae of Busseola fusca were collected from maize fields at an altitude of 2165 m in Njoro, Kenya, and the biology of the pest was then studied in the laboratory. The egg incubation period was 7.5 plus or minus 0.5 days. Of the 188 eggs incubated from a single female, 71.8 percent hatched into viable larvae, 30.4 percent of which experienced diapause while the rest (69.6 percent) had normal development. The larval duration of diapause larvae was longer (238.5 plus or minus 13.1 days) than that of non-diapause larvae (40.9 plus or minus 0.5 days). The pupal period was 19.5 plus or minus 2.1 days, and female and male lifespans were 5.8 plus or minus 3.1 and 5.3 plus or minus 2.2 days, respectively. Overall, diapause generations performed better than non-diapause ones, as they had a longer oviposition period (3.4 plus or minus 1.1 as against 2.8 plus or minus 2.2 days) and were more fecund (570.2 plus or minus 173.9 as against 318.4 plus or minus 278.0 eggs/female). The sex ratio was approximately 1:1 and observations indicated that females entertained multiple matings.
