Abstract
Numerous species in Family Dermestidae (Coleoptera) are important economic pests of stored
goods of animal and vegetal origin, and museum specimens. Reliance on chemical methods for
of control has led to the development of pesticide resistance and contamination of treated
products with insecticide residues. To assess its practicality as an alternate method of control,
we review the literature on the tolerance of dermestids to extreme hot and cold temperatures.
The information for dermestid beetles on temperature tolerance is fragmentary, experimental
methods are not standardized across studies, and most studies do not consider the role of
acclimation and diapause. Difficulties in determining the diapause status of dermestid larvae
may explain the lack of studies. The few studies that do examine these factors show that they
can greatly increase tolerance to cold temperatures. The use of extreme temperatures will
need to target the most tolerant life stage, which for dermestids at cold temperatures will
potentially be the cold-acclimated individuals in diapause. The development of effective
protocols will be facilitated by studies that clearly and completely describe experimental and
statistical methods, consider factors (life-stage, acclimation, diapause) that increase tolerance
to extreme temperatures, and assess the mortality at various temperatures to develop
mathematical models.
