Predator-prey interactions involving an aquatic insect and zooplanktonic prey of different sizes were investigated to quantify prey mortality exposed to predators. Laboratory experiments were undertaken with the young and adult gerrid Rheumatobates crassifemur to test predation and size selectivity on the cladocerans Daphnia gessneri, Ceriodaphnia richardi, and Bosmina tubicen. Population fluct...

Amphibian predator-insect prey relationships are common in terrestrial habitats, but amphibian larvae are preyed upon by a variety of aquatic hemipterans in aquatic habitats. This paper suggests that the survival of the nymphs of the endangered aquatic hemipteran Kirkaldyia (=Lethocerus) deyrolli (Belostomatidae: Heteroptera) is directly and indirectly affected by the abundance of their amphibi...

Chauliops fallax Scott, 1874 (Hemiptera: Heteroptera: Malcidae: Chauliopinae) is one of the most destructive insect pests of soybean and rice fields in Asia. Here we sequenced the complete mitochondrial genome of this pest. This genome is 15,739 bp long, with an A+T content of 73.7%, containing 37 typical animal mitochondrial genes and a control region. All genes were arranged in the same order...

BACKGROUND DNA barcoding, the analysis of sequence variation in the 5' region of the mitochondrial cytochrome c oxidase I (COI) gene, has been shown to provide an efficient method for the identification of species in a wide range of animal taxa. In order to assess the effectiveness of barcodes in the discrimination of Heteroptera, we examined 344 species belonging to 178 genera, drawn from spec...

Microstructures on insect wings can promote directional drop shedding, and the local orientation of these structures is expected to facilitate drop removal. However, microstructures may exhibit very different orientations at different locations on the wing. Using the march fly Penthetria heteroptera, we propose that local orientation of small hairs (microtrichia) reflects a balance of three non...

Lygus antennal protein (LAP) is an olfactory-related protein of the tarnished plant bug Lygus lineolaris (Hemiptera, Heteroptera: Miridae), a hemimetabolous insect. In previous work, a polyclonal antiserum was generated against the N-terminal sequence of LAP; LAP immunoreactivity was strongest in antennae of adult males, but was also present in antennae of adult females and of nymphs. In the cu...

An underestimated factor that contributes to the decline of insects observed during last year is probably mortality, which caused by mowing grassland. We studied negative impact on arthropod fauna roadside grassland, might serve as potential habitat for prevent their local extinction and corridor dispersal in anthropogenic landscapes. In addition, we if losses due can be mitigated use ‘arthropo...

The infraorder Gerromorpha (Insecta, Hemiptera, Heteroptera) comprises semiaquatic bugs, most of which live on the water surface, among floating plants or at margins bodies. We made collections these insects in Itapecuru and Parnaíba hydrographical basins eastern Maranhão state, northeastern Brazil, from January to December 2019. Based material obtained, we present new rec...

The previously known species of the thread-legged bug genus Ischnobaena Stål, 1871 (Hemiptera: Heteroptera: Reduviidae: Emesinae: Metapterini), namely I. dohrnii 1871, macerrima and staliana Wygodzinsky, 1966, are reviewed diagnosed. Lectotypes designated for macerrima. A new species, castroae sp. nov., from Mindanao Island in Philippines is described photographed. can be distinguished its cong...

We report from Laos for the first time two genera and three species of lace bugs (Hemiptera, Heteroptera, Tingidae). This brings number tingids reported to 25 32 species. The are Eritingis Drake & Ruhoff, 1962 Haedus Distant, 1904, recentis (Drake Poor, 1937), vicarius (Drake, 1927), Trachypeplus jingae Dang, Guilbert Bu, 2013.
