A new minute pirate bug of the genus Scoloposcelis (Hemiptera: Heteroptera: Anthocoridae) from West Malaysia.
Scoloposcelis seidaii sp. nov. is described from the Malay Peninsula based on a single specimen collected under the bark of a decaying tree. This discovery represents the first distribution record of the genus Scoloposcelis from Malaysia. Habitus photographs and diagnosis of S. parallela (Motschulsky, 1863) are provided for comparison with S. seidaii.

متن کاملPresence of the Aphid, Chaetosiphon fragaefolii, on Strawberry in Argentina
Seasonal abundance of the strawberry aphid complex under different agronomic practices in the outskirts of La Plata, Argentina was studied on strawberry, Fragaria x ananassa Duchesne (Rosales: Rosaceae). Aphid densities were low in strawberry fields in which insecticides and fungicides were used. In addition to Aphis gossypii, Aphis fabae, Mysus persicae and Macrosiphum euphorbiae, the aphid, C...
متن کاملMultiple mating in the traumatically inseminating Warehouse pirate bug, Xylocoris flavipes: effects on fecundity and longevity.
Optimal mating frequencies differ between sexes as a consequence of the sexual differentiation of reproductive costs per mating, where mating is normally more costly to females than males. In mating systems where sexual reproduction is costly to females, sexual conflict may cause both direct (i.e. by reducing female fecundity or causing mortality) and indirect (i.e. increased risk of mortality,...
متن کاملThe predatory behavior of the Neotropical social wasp Polybia rejecta.
We experimentally studied the predatory behavior of Polybia rejecta (Vespidae, Polistinae, Epiponini) towards 2-88 mm-long insects attracted to a UV light trap. Foragers, which began to hunt at 6:30, selected 4-14 mm-long prey insects. Prey detection by sight by hovering wasps was confirmed using decoys. After the wasps landed and walked along a sinuous path, prey were detected by contact or fr...
