Bedbugs Love a Crowd, Study Finds01/09/14
THURSDAY, Jan. 9, 2014 (HealthDay News) -- Something to think
about when you have trouble sleeping: Bedbugs grow faster when they
live in groups, a new study finds.
It was known that this occurred among other insects, such as
crickets, cockroaches and grasshoppers, but no such research is
believed to have been done on bedbugs.
The North Carolina State University researchers found that
bedbug nymphs (baby bedbugs) in groups developed more than two days
(7.3 percent) faster than solitary nymphs. The study was published
in the January issue of the
Journal of Medical Entomology.
The researchers also discovered that the growth-related effects
of living in a group are the same regardless of the age of
individual bedbugs in the group. This means newly hatched bedbugs
don't require the company of older bedbugs to have higher growth
"The observations that adults do not appear to contribute to nymph development suggests that eggs can survive and start new infestations without any adults," study corresponding author Coby Schal said in a journal news release.
The researchers said the next step is to determine what sensory
cues bedbugs use to grow faster in groups.
