Species of the genus Protelenomus Kieffer (Platygastroidea, Scelionidae) are phoretic egg parasitoids coreid bugs. The discovery, DNA sequencing, and molecular phylogenetic analysis a species on Cletus punctiger (Dallas) (Hemiptera, Coreidae) shows that is derived lineage Trissolcus Ashmead. treated as junior synonym new , T. siliangae Yan, Chen & Talamas, described from China.

Scelionid egg parasitoids can obtain reliable information on the presence of host eggs by discriminating host gender on the basis of chemical footprints of their co-evolved hosts, with a strong preference for the footprint left by host females. Based on the concept of dietary specialization and infochemical use in natural enemies, it could be predicted that host gender discrimination in special...

trissolcus grandis thomson is a solitary egg parasitoid of sunn pest, eurygaster integriceps puton. although widely distributed, it has often been overlooked in field surveys. our objectives were to develop an efficient rearing technique for t. grandis, and to determine the basic bionomics and demographic parameters, necessary for future augmentative biological control programs. exposure of 0-4...

Studies investigating rickettsial infections in ticks parasitizing wild animals in the Northeast region of Brazil have been confined to the detection of Rickettsia amblyommii in immature stages of Amblyomma longirostre collected from birds in the state of Bahia, and in immatures and females of Amblyomma auricularium collected from the striped hog-nosed skunk (Conepatus semistriatus) and armadil...

The egg parasitoids Trissolcus japonicus (Ashmead) and mitsukurii (Hymenoptera: Scelionidae) are the most effective biocontrol agents of invasive agricultural pest Halyomorpha halys (Stål) (Heteroptera: Pentatomidae) in its native range (east Asia). T. sympatric areas. In northern Italy, where H. is a major fruit orchards, adventive populations both species spreading, artificially released unde...
