Meet Jamora Hamilton, Ph.D., expert in cockroach management and urban entomology and subject of the next installment of our "Standout Early Career Professionals" series.
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.
