I always love a post where I can re-use my (so far) lone roach photo!

Pest control practices will have to evolve just as fast to kill the much-hated insects

Unlike many humans, it’s not because they’re suddenly watching their figure; rather, German cockroaches have inadvertently outwitted human pest control tactics by evolving to dislike sugar, specifically glucose.

That could have huge implications for the population of cockroaches worldwide, which is of particular concern given their propensity to spread bacteria and disease.

…  Dr. Ayako Wada-Katsumata and a team of entomology researchers found evidence of significant changes involving sugar-averse German cockroaches and mating habits.

… Surprisingly, researchers found these [sugar averse] roaches were unwilling to complete traditional roach mating behavior (accepting what the research study refers to as “nuptial gifts” or “nuptial feedings.”) Further, these glucose-adverse female roaches chose not to complete the mating process, meaning there wouldn’t be any reproduction.

… So why is this research important? For one thing, roaches are a prominent pest — they tend to spread through human settlements, and can spread disease and cause other health problems in humans. And it is possible that this mutation could increase the roach population.

They’re not looking for sugar daddies!

German cockroaches are evolving to dislike sugar and female cockroaches are avoiding mating with their sugar-loving male peers, according to a study from North Carolina State University published in Nature in May.

Dr. Ayako Wada-Katsumata and his team of entomology researchers found that the most effective mating pairs in the study were between female and male roaches who both avoided sugar and that the least productive pairing were between female roaches who avoided sugar and male roaches who ate sugar.

In order to get lucky in the bedroom, the sweet-toothed male roaches quit sugar in order to appease their female counterparts, the study found.

This could pose health and housekeeping problems for humans.

Since pesticide products are made with glucose, a simple sugar, to mask its less sweet toxic ingredients, roaches’ diet and mating habits could lead to a new generation of pesticide resistant bugs, Salon reported.
