Cockroaches evolve new sex moves to avoid sugar traps.

The use of glucose in cockroach traps has led to some female cockroaches developing an aversion to the sugar, affecting their mating behavior. Male cockroaches have adapted by changing the composition of their "nuptial gift," including slashing the glucose content and shortening the courtship process. Glucose-averse males start mating almost twice as fast as other cockroaches. The study highlights the importance of understanding glucose aversion in cockroaches to develop new ways to control their numbers.
