Abstract
This thesis focuses on the population ecology of the American cockroach,
Periplaneta americana (L.), in sewers. In addition, the potential of using an oothecal
parasite, Aprostocetus hagenowii (Ratzeburg), in controlling American cockroaches
was evaluated in the aspects of rearing improvement and biological control of the
cockroaches.
Population ecology of P. americana were studied in three sewers in the
Minden Campus of Universiti Sains Malaysia, Penang from September 2008 to
October 2009. Adults and nymphs were active throughout the study period based on
an average monthly trap catch of 57–97 adults and 79–99 nymphs. The overall mean
proportion of adults and nymphs at the three sewers was 0.47 and 0.53, respectively.
The proportion of marked males and females did not differ significantly from the
proportion of recaptured marked males and females. However, the mean number of
times a female was recaptured was significantly greater than that of males.
Recaptured marked females (24.7%) were recorded moved more between manholes
compared to that of males (19.4%). Majority (90.4%) of the cockroach movement
made between manholes was within the distance of 2–20 m; one male moved 192 m.
Trap catches of cockroaches were positively correlated with daily mean temperature
while cockroach movements was correlated with the mean daily minimum
temperature.
