dc.description.abstractThe selected biological parameters such as adult longevity, fecundity and nymphal development of the Turkestan cockroach, Blatta lateralis (Walker) under laboratory controlled environment in comparison with the brown-banded cockroach, Supella longipalpa (Fabricius) and the German cockroach, Blattella germanica (L.) were studied. Results obtained demonstrated that the adult longevity of B. lateralis was the highest among the three cockroach species while the male to female ratio skewed towards the male with a ratio of 1.12:1.00. Among the three species, the adult females of B. lateralis were able to produce a significantly high number of oothecae (with a maximum number recorded at 39 oothecae) over their life span. However, the percentage of oothecae hatchability of B. lateralis was lowest (46.79 %) while its nymphal development period was highest (163.02 ± 2.50 days), making the B. germanica the more successful species as a pest in causing an infestation among the three species. However, under extreme conditions in the absence of food and water, B. lateralis compete relatively well with the highest longevity. Although the reproduction was observed to have been impaired when the cockroaches were deprived of either food or water or both continuously, B. lateralis was able to produce a maximum of one ootheca which successfully hatched and produced live nymphs. Nonetheless, when food and water were provided partially (i.e. every three days or every seven days), B. germanica still displayed itself as the more successful species among the three, in terms of adult longevity and reproduction.en_US
