Abstract
This thesis focuses on the effects of artificial and natural feeding system on the
biological parameters of both common (Cimex lectularius L.) and tropical bed bugs
(Cimex hemipterus [Fabricius]), and the climbing ability of both species on pitfall style
monitoring traps. The feeding effectiveness of an artificial feeding system (Hemotek®
membrane feeding system) for Cimex lectularius (Monheim and Sydney strains) and
C. hemipterus (Madam Mo, Tanjung Tokong, Queensland and KL strains) using two
types of rabbit blood (defibrinated [DRB] and heparinized [HRB]) were compared
with natural feeding on a human host. The effects on biological parameters (feeding
rate, amount of blood fed, adult emergence rate, body length, body width, and distance
between the eyes, number of eggs produced and egg hatchability rate) of both species
were compared. Results found that there was no significant difference (P > 0.05)
between DRB and HRB, on the biological parameters of all the bed bug strains and
species tested. When tested on a human host, similar results were obtained, with
exception to Monheim susceptible strain producing significantly (P < 0.05) more eggs
on human blood compared to those of DRB and HRB. Next, the climbing abilities of
two bed bug species, Cimex lectularius L. and Cimex hemipterus (F.) were determined
by evaluating their escape rates from smooth surface pitfall traps using four
commercial bed bug monitors (Verifi™ Bed Bug Detector, ClimbUp® Insect
Interceptor, BlackOut™ Bed Bug Detector, and SenSci Volcano™ Bed Bug Detector).
Unlike C. lectularius, adult C. hemipterus were able to escape from all traps. On the
other hand, no or low number nymphs of both species escaped, depending on the
evaluated traps. Examination on the vertical friction force of adults of both species
revealed a higher vertical friction force in C. hemipterus than in C. lectularius.
Scanning electron micrograph observation on the tibial pad of adult bed bugs of C.
hemipterus showed the presence of a greater number of tenent hairs on the tibial pad
than on that of adult C. lectularius. No tibial pad was found in the fourth and fifth
instars of both species. Near the base of the hollow tenent hairs is a glandular
epithelium that is better developed in adult C. hemipterus than in adult C. lectularius.
