Insights into Brochosome Distribution, Synthesis, and Novel Rapid-Release Mechanism in Maiestas dorsalis (Hemiptera: Cicadellidae).

ABSTRACT: The leafhopper family Cicadellidae, comprising over 22,000 species, exhibits a unique behavior of anointing their bodies with excretions containing brochosomes. Brochosomes are synthesized in the distal segment of the Malpighian tubules and serve various functions, including hydrophobic protection and defense against pathogens and predators. In this study, we investigated the distribution, synthesis, and release mechanisms of brochosomes in the rice pest leafhopper Maiestas dorsalis. Using SEM and TEM, we observed brochosomes' consistent coverage on the integument throughout the insect's life cycle. Moreover, we identified four distinct developmental stages of brochosome synthesis within the distal segment of the Malpighian tubules, originating from the Golgi region. Most importantl
