Chinavia hilaris (Say), Euschistus servus (Say), Euschistus tristigmus (Say), and Thyanta custator custator (F.) (Hemiptera: Pentatomidae) are serious pests of crops in the southeastern United States but little is known concerning their dispersal from noncrop hosts in woodlands into crops. This 2-yr study was conducted to investigate whether elderberry [Sambucus nigra subsp. canadensis (L.) R. ...

The chinch bug, Blissus occiduus Barber (Hemiptera: Blissidae), is an important pest of buffalograss, Buchloë dactyloides (Nutall) Engelmann and potentially other turfgrass, crop, and non-crop hosts. Choice studies documented the number of B. occiduus present on selected turfgrasses, crops and weeds, and provided important insights into the host preferences of this chinch bug. Grasses with the ...

Stress and vigor are endpoints on a continuum of the suitability of plants for insect herbivores. Senescence-feeding insects, such as the chrysanthemum lace bug, Corythucha marmorata (Uhler) (Hemiptera: Tingidae, Tingitini), are hypothesized to benefit from any stressor hastening the senescence of plant tissues, such as drought. They are also hypothesized to prefer feeding and ovipositing on st...

The Hemiptera comprise the most species-rich order of hemimetabolous insects. Members a number superfamilies, notably especially more basal ones such as white flies, psyllids and aphids, belong to destructive agricultural insects known worldwide. At other end phylogenetic tree are hemipterans that notorious medical pests (e.g. kissing bugs). Most hemipteran species good flyers, lipid oxidation ...

Rio Grande do Sul (RS) is the southernmost state in Brazil and includes areas within Pampa Atlantic Forest biomes. The semiaquatic bugs (Hemiptera, Heteroptera, Gerromorpha) from RS are poorly known, with only 14 previously recorded species. We carried out two expeditions this state, 2002 2019, across 19 municipalities. Here, we provide new records for species, of which 13 first time five have ...

(1) Assess the distribution and abundance of four common, flower-visiting, predatory Southern California assassin bug species (Hemiptera: Reduviidae) on their host plants in sage scrub and chaparral habitats of the Shipley-Skinner Reserve. (2) Use gut metabarcoding analyses to test the hypothesis that native pollinators constitute a significant proportion of assassin bug diets, and that the die...
