2015

Abstract The genus Isometocoris Carvalho and Sailer is reviewed and I. penicillus, new species, from Brazil is described. Diagnoses of the genus and included species I. blantoni Carvalho and Sailer and I. penicillus, n. sp., are given; a color adult habitus photo of both Isometocoris species, male genitalic drawings of Isometocoris penicillus n. sp., and scanning electron micrographs of selected structures of I. blantoni are provided; and an identification key is given to help distinguish the two included species. Isometocoris is transferred from the subfamily Psallopinae to the Cylapinae, where it is placed in the tribe Fulviini. Psallopinae is reduced to tribal level (Psallopini, new stat…

2014

Ochetostethomorpha secunda sp. nov. from Namibia, the second species of the South African endemic genus is described, illustrated, and compared with O. nollothensis Schumacher, 1913. The new species is the third of the subfamily Sehirinae known from Namibia. Moreover, a DNA barcode sequence was generated for this new species (827 bp of cytochrome oxidase I) and was deposited in GenBank.

Pretarsal structures in the family Parastrachiidae (Hemiptera: Heteroptera: Pentatomoidea)

2010

Parastrachiidae, for a long time regarded as a subfamily within the Cydnidae (e.g., Schaefer et al. 1988; Schuh and Slater 1995; Gapud 1991), was raised to family level by Sweet and Schaefer (2002), and this position was then accepted by many heteropterists (e.g., Lis and Heyna 2001; Lis and Schaefer 2005; Hironaka et al. 2007; Schaefer and Kikuhara 2007; Lis 2010).

Sub-lethal effects of deltamethrin on walking behaviour and response to host kairomone of the egg parasitoid Trissolcus basalis.

2002

The lethal doses of the pyrethroid deltamethrin were estimated for the egg parasitoid Trissolcus basalis (Wollaston) (Hymenoptera: Scelionidae), and the sub-lethal effects of an LD25 on female walking behaviour were evaluated. Linear speed of treated parasitoids was reduced compared with that of untreated ones for a period of up to 24 h. The sub-lethal effects of deltamethrin on parasitoid response to patches contaminated by a contact kairomone from its host, Nezara viridula L (Heteroptera: Pentatomidae), was also evaluated. Both treated and untreated parasitoids responded to host-contaminated patches by increasing residence time and decreasing linear speed. However, treated females showed …

The response of Trissolcus basalis to footprint contact kairomones from Nezara viridula females is mediated by leaf epicuticular waxes.

2009

Chemical footprints left behind by true bugs are perceived as contact kairomones by scelionid egg parasitoids. Female wasps encountering a contaminated artificial substrate display a characteristic arrestment posture, holding the body motionless and antennating the surface. In the system Nezara viridula (L.) and its egg parasitoid Trissolcus basalis (Wollaston), previous studies have shown that the kairomone mediating such behavior is part of N. viridula's cuticular hydrocarbons (CHC) and furthermore that the wasp's ability to discriminate host male and female footprints is mainly based on the presence/absence of nonadecane (nC(19)). In this study, the effect of epicuticular waxes of leaves…

Pre-release risk assessment of the egg-parasitoid Gryon pennsylvanicum for classical biological control of Leptoglossus occidentalis.

2013

Leptoglossus occidentalis Heidemann (Heteroptera: Coreidae) is a North American conifer seed pest that was accidentally introduced to Europe. In the Mediterranean area, it threatens the production of Pinus pinea Linna- eus seeds. The egg-parasitoid Gryon pennsylvanicum (Ashmead) (Hymenop- tera: Platygastridae), the main natural enemy in the native range of L. occidentalis, was imported from British Columbia to Italy. Pre-release risk assessments were made under quarantine conditions by no-choice tests conducted with na€ıve and experienced G. pennsylvanicum offering single eggs of target and non-target species for varying exposure times (1, 4, 48 h). G. pennsylvanicum successfully parasitize…
