| Summary: | a layer of glandular epithelium surrounding a central lumen accessory gland also was studied to investigate its role in affected the accessory glands of surviving females. The and shape at different stages of the ovarian cycle, by a mesh network of tubercle extensions. Rafts of eggs are cells of the gland were more acidophilic than glands from Consequently, hatchability was greatly reduced. The female covering the mesh network that formed the air/water jacket cytoplasm of the accessory glands as the cementum was eggs is made up of a series of cone-like tubercles surrounded electron microscopy revealed that the surface of individual Examination of egg rafts from Cx. quinquefasciatus using held together by an extrachorionic secretion located between Mosquitoes exposed to sublethal doses of the insect growth not exposed to methoprene. Eggs from treated females had organelles within the gland cells indicated that they produce organized and more loosely constructed than those of females oviposition. Larval exposure to sublethal doses of methoprene regulator, methoprene, laid egg rafts that were less secreted faster than it could be produced by the gland. shorter tubercles, and excess cementum coated the egg suggesting that its secretary activity was correlated with the development times, did not appear to be dosage dependent. the extrachorionic secretion that helps hold the eggs the synthesis of egg raft secretions. The gland consisted of the tubercles and by mechanical interdigitation of tubercles. These effects on the female accessory gland, as well as on together in the raft. The accessory gland differed in size untreated controls. Vacuoles began appearing in the used for respiration by the developing embryos. which connects to the common oviduct. Examination of the |
