Juvenile hormone and insulin suppress lipolysis between periods of lactation during tsetse fly pregnancy.

Highlights: [•] Tsetse flies possess two juvenile hormone receptors, Methoprene-tolerant and germ cell expressed, similar to Drosophila. [•] Juvenile hormone and insulin promote lipid accumulation in tsetse flies. [•] Juvenile hormone and insulin leads to increased fat storage during non-lactating periods. [•] Our results indicate the insulin and juvenile hormone are key to nutritional mobilization during tsetse lactation. [Copyright &y& Elsevier]
