Nymph and adult biology of Dichelops melacanthus (Dallas) (Heteroptera: Pentatomidae) feeding on cultivated and non-cultivated host plants.
The biology of the pentatomid Dichelops melacanthus (Dallas) feeding on cultivated and non-cultivated plants was studied in the laboratory. Nymph mortality varied from approximately 60 on corn (seed mature) to 77% on wheat (ear immature); no nymphs survived on seedlings of corn or wheat. Nymph developmental time on soybean, corn or wheat (seed, pod or ear) varied from 25.5 to 32.8 days. Body we...

متن کاملEffect of diet on male reproductive tract of Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae).
The morphology and histology of the reproductive tract of males of the predator Podisus nigrispinus (Dallas) fed on different diets were studied. P. nigrispinus was fed on diets of: larvae of Alabama argillacea (Hübner), Tenebrio molitor L., Musca domestica L., and an artificial diet. The male reproductive tract, independent of diet, showed testes with intense red coloration in a compact, circu...
متن کاملContributions to the knowledge of Dichelops Spinola: description of a new species of Dichelops (Diceraeus) and of the male of Dichelops (Prodichelops) divisus (Hemiptera: Heteroptera: Pentatomidae: Pentatominae: Carpocorini).
A new species of Dichelops (Diceraeus) Dallas and the so-far unknown male of Dichelops (Prodichelops) divisus (Walker, 1867) are described, based upon morphological characters. D. (Dice.) caatinguensis sp. nov. is compared to the other four species of Diceraeus. Revised keys to separate the subgenera of Dichelops and the species of Diceraeus are also presented. D. (P.) divisus male is described...
متن کاملStructure and chemical analysis of the metathoracic scent glands of Carpocoris fuscispinus (Boheman, 1851) (Heteroptera: Pentatomidae) from Turkey
Metathoracic scent glands (MTGs) of Carpocoris fuscispinus (Boheman, 1851) (Heteroptera: Pentatomidae) were studied in adult females and males. Structures of the glands were investigated using scanning electron microscopy, and the volatile fraction was analyzed by gas chromatography-mass spectrometry. MTGs of C. fuscispinus have many features in common: a large, median reservoir and paired late...
