Bugging out! Female cockroaches breed even better in groups

A new study sheds light on how female cockroaches breed.

Female cockroaches are egg-cellent at sisterhood.

A new study reveals that groups of the buggy little ladies can reproduce for years without a male, reports a Japanese study.

The research, published in the journal Zoological Letters, focused on asexual reproduction — which occurs when female cockroaches don’t have males in proximity, a process called parthenogenesis.

In the study, scientists at Hokkaido University isolated one or several adult female American cockroaches in containers.

The single, lonely female took more time to produce an egg case than her communal counterparts.

“Female cockroaches promote asexual egg production when they are together, not alone,” said author Hiroshi Nishino.

First, the good news: The results could help rid humanity of these creepy crawlies.

“Understanding the physiological mechanism behind the reproductive strategies,” he added, “should help us find more effective ways to exterminate pest cockroaches in the future.”

The bad news? If female cockroaches don’t even need males to reproduce, it means that sisters really are doing it for themselves.
