Abstract Stink bug (Hemiptera: Pentatomidae) development typically requires feeding on a diversity of plant species and various tissues. During feeding, stink bugs discharge salivary enzymes with roles in extraoral digestion countering defense responses. Although previous research has described digestive proteins from bugs, less is known the involved suppression defenses. We sequenced transcrip...

Since October 2019, chinch bugs have been detected in large sunken dead patches of St. Augustinegrass (Stenotaphrum secundatum) lawns different locations Lisbon and Setubal districts, Portugal. Based on morphological molecular studies, using mitochondrial Cytochrome C Oxidase subunit I (COI) gene, the collected insects were identified as Blissus insularis (Hemiptera, Heteroptera, Blissidae). Th...

Hemiptera, the largest non-holometabolous order of insects, represents approximately 7% of metazoan diversity. With extraordinary life histories and highly specialized morphological adaptations, hemipterans have exploited diverse habitats and food sources through approximately 300 Myr of evolution. To elucidate the phylogeny and evolutionary history of Hemiptera, we carried out the most compreh...

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...

Native and invasive stink bugs (Hemiptera: Pentatomidae) and the closely related invasive Megacopta cribraria (Hemiptera: Plataspidae) are agricultural pests in the southeastern United States. Natural enemies, from various phyla, parasitize these pests and contribute to population regulation. We specifically investigated Nematoda infections in pentatomid and plataspid pests in one soybean field...

The Paraneoptera (Hemipteroid Assemblage) comprises the orders Thysanoptera (thrips), Hemiptera (bugs), Phthiraptera (lice) and Psocoptera (booklice and barklice). The phylogenetic relationships among the Psocodea (Phthiraptera and Psocoptera), Thysanoptera and Hemiptera are unresolved, as are some relationships within the Psocodea. Here, we present phylogenetic hypotheses inferred from SSU rDN...

In recent years, the common bed bug, Cimex lectularius L. (Hemiptera: Cimicidae), became a major public health concern in urban communities. Bed bugs are notoriously difficult to control, and their bites are not tolerated by most people. The public has an urgent need for materials and methods to reduce bed bug introduction and bites during work, travel, or sleep. A repellent product will help a...

Bed bugs, Cimex lectularius L. (Hemiptera: Cimicidae), are a fast-growing urban pest of significant public health importance in the United States and many other countries. Yet, there is very little field research on the ecology of this pest due to its near absence in the United States and most developed nations for several decades. We investigated characteristics of the bed bug infestation and ...
