Monitoring for cockroach infestations in homes and buildings is hindered by a lack of effective and practical attractants, but researchers at Rutgers University say a mix of extracts from apple and blueberry has proven highly effective in lab and field settings and could lead to more successful cockroach integrated pest management programs.
A study of the spatial distribution of German cockroaches in a high-rise apartment building found infestations were clustered in groups of adjacent units. But a building-wide integrated pest management program can be successful in eliminating most infestations and, importantly, stopping the cockroaches from migrating from one apartment to the next.
Insects have evolved a variety of mechanisms to try to overcome the effects of insecticides—including, in some cases, help from the bacteria and other microbes living in insects' guts. A growing number of studies indicate a link between symbiotic microbes and insecticide resistance in a diverse range of insects.
A study by researchers at North Carolina State University demonstrates that female cockroaches reproduce faster when they are touched by other cockroaches. In fact, they found that even the touch […]
