Publisher Summary This chapter reviews the evidence for endocrine influences on division
of labor in insect societies. Juvenile hormone (JH) has been studied most extensively. The …

Publisher Summary This chapter discusses the juvenile hormones (JH). The JH, a family of
acyclic sesquiterpenoids, are essential to insect development and reproduction. This …

Publisher Summary This chapter discusses the endocrine control of insect polyphenism.
Polyphenism in insects is associated with some of the most striking and successful life …

Most temperate multivoltine insects enter diapause, a hormonally controlled developmental
suspension, in response to seasonal photoperiodic and/or thermal cues. Some insect …

We describe the cloning of the first hymenopteran vitellogenin receptor (VgR) cDNA from the
imported fire ant, Solenopsis invicta, an invasive pest. Using reverse transcription …

Background The popular view on insect sociality is that of a harmonious division of labor
among two morphologically distinct and functionally non-overlapping castes. But this is a …

In ant species in which mating flights are a strategic life‐history trait for dispersal and
reproduction, maturation of virgin queens occurs. However, the specific molecular …

Juvenile hormone (JH) is an important regulator of development and physiology in insects.
While in many insect species, including bumble bees, JH functions as gonadotropin in …

Studies were conducted on the physiological and hormonal changes following the release
of alates from developmentally suppressive pheromones produced by mature queens of the …

Division of labor is one of the most striking features in the evolution of eusociality. Juvenile
hormone (JH) mediates reproductive status and aggression among nestmates in primitively …
