Insect gut immunity is the first line of defense against oral infection. Although a few immune-related molecules in insect intestine has been identified by genomics or proteomics approach with comparison to well-studied tissues, such as hemolymph or fat body, our knowledge about the molecular mechanism underlying the gut immunity which would involve a variety of unidentified molecules is still ...
Insect pests such as termites cause damages to crops and man-made structures estimated at over $30 billion per year, imposing a global challenge for the human economy. Here, we report a strategy for compromising insect immunity that might lead to the development of nontoxic, sustainable pest control methods. Gram-negative bacteria binding proteins (GNBPs) are critical for sensing pathogenic inf...
Interactions between insect hosts and their parasites are significant because their parasites can also be parasites of humans and of species that we utilize. Host-parasite interactions are complex, even in insects, and there can be heterogeneous outcomes in infection success, load, virulence and transmission, with consequences for the evolution of hosts and their parasites, and also for epidemi...
Manduca sexta, known as the tobacco hornworm or Carolina sphinx moth, is a lepidopteran insect that is used extensively as a model system for research in insect biochemistry, physiology, neurobiology, development, and immunity. One important benefit of this species as an experimental model is its extremely large size, reaching more than 10 g in the larval stage. M. sexta larvae feed on solanace...
Insect herbivores simultaneously experience bottom-up effects of plant defensive chemistry and the top-down natural enemies. At intersection these are herbivore immune systems, traits that have largely been overlooked in studies plant-insect interactions. Most previous demonstrated compromised immunity feed on plants with higher chemistry. Many used embedded microfilaments or silica beads as pr...
Background: Endoparasitoid wasps inject venom proteins at oviposition to alter host immunity. Results: The venom of Leptopilina boulardi but not of a related species contains an active extracellular SOD. Recombinant SODs inhibit the Drosophila host phenoloxidase activity. Conclusion: An extracellular SOD is secreted and active in an insect fluid. Significance: SODs may be used as immune suppres...
