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...

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...

The southern green stink bug Nezara viridula (Linnaeus) is a polyphagous species that causes economic damages to many crops in Bulgaria. aim of this study was identify the parasitoid could suppress populations viridula. A lot agricultural were inspected region Plovdiv, Bulgaria, for presence egg parasitoids and imaginal pest. Egg masses adults collected during field surveys 2019-2021 Southern o...

The scelionid parasitoid Trissolcus basalis (Wollaston,1858) has been detected in Belgium for the first time based on specimens reared from a parasitized egg mass of Nezara viridula (Linnaeus,1758) collected an urban garden at Sint-Amandsberg, Ghent. Identification was adult morphology and DNA barcoding. This is presently believed to be northernmost record Europe T. could consequence northward ...
