Bed bugs under self-attack

Bed bugs under self-attack

BedbugBed bugs have always posed an increasing problem in several industries which include but not limited to agriculture, housing, travel and hospitality.
In a research published in the current issue of the Journal of Medical Entomology, the scientists at Ohio State University determined that bed bugs exposed to the two bed bug alarm pheromone ingredients known as (E)-2-hexenal and (E)-2-octenal applied with a silica gel desiccant dust
made for a lethal combination.
The bed bugs exposed to Drie-die died with water loss about 21 percent more than the untreated bugs, doubled when either pheromone ingredient was used and tripled when combined. According to the research, treated with a combination of these ingredients, the younger bed bugs died in
a day, the adult female bugs died in 6-1/2 days which were extraordinarily amazing compared to 4 days and 17 days, respectively, if exposed only to dessicant dust without the alarm pheromones.
They further experimented whether the same ingredients would encourage the bed bugs to get out of their hiding places. The researchers created an experimental habitat and all bed bugs tested came out of the hiding places within five minutes of the alarm pheromone treatment.
While these experiments proved highly satisfactory to a smaller scale environment, it was envisaged that the technique be applied to larger environments with bed bug infestations.
The researchers opposed the repeated use of spray pesticides on bed bugs as ‘they boost the survival of bed bugs with that resistance’. They noted that, “Jit’s better to use old pesticides in new ways,” rather than venture on finding new ones.
