Bald-faced hornet to laying eggs while the workers take over all other necessary housekeeping tasks. At some point, sometime before the midpoint of colony life, the colony will begin to invest energy in producing reproductives as well. This marks the transition into the reproductive stage. There is an extensive time period where both workers and reproductives are raised. Production of both castes limits the size of the work force. However, an early switching time is highly adaptive for social wasp colonies in limiting the risk of total loss. In a sampling of 50 colonies taken in Maryland in 1977, workers were produced
Insect diuretic hormones The complex is only present in lepidopteran larvae and some beetle species. Little is known about the hormonal control of fluid uptake by the cryptonephric complex, which is certain to play an important role in the species in which it occurs. First three letters of genus added to first two letters of the species name. For example, a 37-residue diuretic peptide from Tenebrio molitor will be named Tenmo-DH37. Insect diuretic hormones Insect diuretic hormones are hormones that regulate water balance through diuretic action. The insect excretory system, responsible for regulating water balance in the insect, comprises the Malpighian tubules and
