Abstract

Cockroaches such as the American and German cockroaches are considered by most humans as pest. This is the tag concept of cockroaches in the Philippines. A review on the studies of cockroaches five years ago was undertaken. Most of the researches that had been conducted were influence on the parasitic effects of cockroach to human society and its role as vector in transmitting unwanted medical diseases. Later, there were studies conducted on controlling these insects using entomopathogenic nematodes. Subsequently, researchers went into the in vivo aspect wherein they studied the antibiotic resistance of bacterial strains isolated in the body regions (tagmata) of these cockroaches. They also isolated protozoans and macroscopic nematodes associated with these cockroaches. Recently, entomologists are concentrating on the mechanical and physiological aspect of these creatures. They dwell on the mechanical features on the tracheal tubes of cockroaches using innovative ring system. Scientists also researched on the different enzymes associated in the gut of cockroaches and their synergistic effect on their body system as well as their industrial purposes. Also, they subjected internal organs exposed to some extracts into histopathological studies. Finally, their ecology (diversity and abundance) and systematics (nomenclature and taxonomy) are still the main focus of entomologist nowadays to further elucidate their noteworthiness in society and not just a “nuisance” species in the locality.
