Experiments on a mealybug infesting apple and a mealybug infesting catalpa
1. The developing time of the mealybug from catalpa exceeded that of the mealybug from apple. 2. In no experiment did cross-breeding of the mealybug from apple and from catalpa take place. 3. Each mealybug was able to live successfully on both hosts. 4. The parasites, Clausenua purpurea Ishii, from …

Genetic differentiation of the parasitoid, Cotesia congregata (Say), based on host-plant complex
… on tobacco (Nicotiana tabacum L.) and Ceratomia catalpae, (Haworth) on catalpa (Catalpa bignonioides Walker), in the mid-Atlantic region of North America using seven microsatellite loci and the mitochondrial COI locus. Microsatellite allele frequencies were differentiated based on host-plant …

Ecology of the Brown Marmorated Stink Bug (Hemiptera: Pentitomidae): Oviposition on Different Trees, Nymphal Development on Various Vegetable Hosts, and Assessment of a Bacterial Pathogen
… sampled, H. halys laid the most egg masses on catalpa, Catalpa bignonioides, while aggregation lure had no effect on the number of eggs laid. Across host trees, egg masses were more commonly found in trees with fruiting structures present. An additional study was conducted on a red-sternum …

Investigation of pre- and post-zygotic reproductive barriers between two host-plant complex races of the parasitic wasp Cotesia congregata (Say) [Hymenoptera: Braconidae]
… originating from hosts on tobacco and catalpa. We compared male responses to female pheromones, elements of male acoustic courtship signals, and breeding success between the two races. Males responded to pheromones from both sources and male courtship signals showed only subtle …

Host plant effects on the biology, behavior and ecology of brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae)
… and survival than was apple, tree of heaven, or catalpa and that nymphal performance was enhanced on mixed host diets. Nymphs reared on different host plant diets yielded adults that differed in protein, sugar or lipid content, offering new insights into plant diet effects on H. halys nutrition. …
