[Fabales: Fabaceae]) and other legume crops in the United States. Initially discovered in Georgia, M. cribraria rapidly expanded across the southeast until 2014 when a significant decline in its population was observe...
متن کاملGut symbiotic bacteria of the genus Burkholderia in the broad-headed bugs Riptortus clavatus and Leptocorisa chinensis (Heteroptera: Alydidae).
The Japanese common broad-headed bugs Riptortus clavatus and Leptocorisa chinensis possess a number of crypts in the posterior region of the midgut, whose lumen contains a copious amount of bacterial cells. We characterized the gut symbiotic bacteria by using molecular phylogenetic analysis, light and electron microscopy, in situ hybridization, and PCR-based detection techniques. Restriction fr...
متن کاملAn Old Remedy for a New Problem? Identification of Ooencyrtus kuvanae (Hymenoptera: Encyrtidae), an Egg Parasitoid of Lycorma delicatula (Hemiptera: Fulgoridae) in North America
Spotted Lanternfly, Lycorma delicatula (White) is a recently introduced pest of Tree-of-Heaven, Ailanthus altissima (Mill.) Swingle in North America. Natural enemy surveys for this pest in Pennsylvania in 2016 recovered an encyrtid egg parasitoid from both field collections and laboratory rearing of field-collected L. delicatula egg masses. Both molecular and morphological data confirm that the...
متن کاملDevelopment of endosulfan tolerant strain of an egg parasitoid Trichogramma chilonis Ishii (Hymenoptera: Trichogrammatidae).
A strain of T. chilonis, an egg parasitoid of lepidopteran pests tolerant to the most commonly used cyclodiene insecticide--endosulfan was developed in the laboratory. Tolerance to endosulfan was induced by exposing adult parasitoids sequentially from a sub-lethal concentration (0.004%) to the field recommended concentration (0.09%). The strain acquired tolerance to the insecticide after 341 ge...
متن کاملDescription of three new species of Ooencyrtus (Hymenoptera: Encyrtidae) from China.
Hymenoptera parasitoids of Megaloptera, particularly the family Corydalidae, are rarely found. Ooencyrtus Ashmead is a genus that attacks eggs of many orders of Insecta, including Megaloptera. Here, three species, O. longicauda sp. n., O. noyesi sp. n. and O. protohermeasis sp. n. are described. Two of them, O. longicauda and O. protohermesis were reared from eggs of corydalids (Megaloptera: Co...
