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
… from these studies offer insight into H. halys development on vegetable hosts and oviposition preferences on different host trees.

Environmental controls in the seasonal succession and synchronization of development in some pond species of damselflies (Odonata: Zygoptera)
… seasonal succession and synchronization of development in seven species of pond-dwelling Zygoptera were investigate. A three phase succession was observed. Three species of Coenagrionidae, Coenagrion angulatum, C. resolutum and Enallagma boreale which overwintered as nymphs, emerged …

Bionomics of the anthocorid, Orius insidiosus (Say) in Virginia apple orchards
… IPM programs currently being developed. Egg and nymphal development of O. insidiosus was studied at 17°, 23°, 29°, and 35°C. Nymphs were supplied with an excess of the European red mite, Panonychus ulmi (Koch). There was a linear relationship between development rate (l/Days) of O. insidiosus and …

Evaluation of Multiple Insecticidal Products for Control of the Common Bed Bug (Cimex lectularius (L.))
… the effect of hydroprene exposure on bed bug development. Although hydroprene did not appear to interfere with nymphal development, fifty percent of the bed bugs died during the final molt. The bed bugs which survived to adulthood showed no reduction in fecundity when compared to control …

Population studies of the potato leafhopper, Empoasca fabae (Harris), on alfalfa, Medicago sativa L.
… single stems collected on each sample date. The nymphal sampling technique using 0.946 liter ice cream containers with dichlorvos squares (ca 1.2 cm²) glued in the bottom of the container was efficient in estimating nymphal densities within 20 to 30% C.V. based on 100 three-stem bouquets …

Host plant effects on the biology, behavior and ecology of brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae)
… showed that peach was much more suitable for nymphal development 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, …

Life History of the Common Bed Bug Cimex lectularius L. in the U.S.
This study quantifies the rate of bed bug nymphal development, mortality, fecundity and survivorship during starvation for wild caught resistant populations. I then compare some of these characteristics with two susceptible strains. I found that resistant populations develop faster and exhibit less …

Aspects of the ecology of Scolypopa australis (Walker) (Homoptera:Ricaniidae) and its parasite Centrodora scolypopae (Valentine) (Hymenoptera: Aphelinidae)
… frequency vegetation sampling method and the nymphal and adult stages by direct counting. The S. australis nymphal populations ranged from 200-400/m² in the first three generations studied, then fell to below 100/m² after a cold summer in 1982-83. S. australis overwintered as eggs laid mainly …

Microhabitat, microbiota, mitochondria and the epigenome shape the biparental legacy of heat exposure in a tropical arthropod
… passed to offspring intergenerationally. During nymphal development, C. scorpioides were placed in incubators programmed to diurnally fluctuate in correspondence with ambient temperature measurements from rainforest habitats found in Chapter 1. A split-brood design was employed where, upon birth, …
