This study aimed at identifying the ecological characteristics of Triatoma patagonica Del Ponte 1929 (Hemiptera: Reduviidae) and evaluating the epidemiological importance of this species at its southernmost distribution limit. We carried out two surveys in the Province of Chubut, in summer and in spring, 1998. In each survey, we interviewed local health care agents for triatomine recognition an...

The common bed bug, Cimex lectularius L. (Hemiptera: Cimicidae), is a blood-feeding ectoparasite which experienced world-wide resurgence during recent decades. The control of bed bugs is often challenging, due to their cryptic nature and resistance to commonly used insecticides. In this study, we evaluated the effect of the antiparasitic drug moxidectin on bed bug survival, reproduction, and de...

The influence, if any, of 5m wide, feral, herbaceous field borders on pest and beneficial arthropods in commercial cotton, Gossypium hirsutum (L.) (Malvales: Malvaceae), fields was measured through a variety of sampling techniques over three years. In each year, 5 fields with managed, feral vegetation borders and five fields without such borders were examined. Sampling was stratified from the f...

The products of the HOM/Hox homeotic genes form a set of evolutionarily conserved transcription factors that control elaborate developmental processes and specify cell fates in many metazoans. We examined the expression of the ortholog of the homeotic gene Sex combs reduced (Scr) of Drosophila melanogaster in insects of three divergent orders: Hemiptera, Orthoptera and Thysanura. Our data refle...

Stink bugs (Hemiptera: Pentatomidae) are economic pests of a variety fruit crops across the southeastern USA, and damage by stink to peaches is common. The landscape surrounding orchards may influence bug distribution dispersal into this commodity, but such patterns vary over growing season. Accordingly, control should be targeted seasonally towards habitats that effectively reduce or prevent p...

BACKGROUND AND AIMS Macaranga (Euphorbiaceae) is a large genus of dioecious trees with approx. 260 species. To date, only one pollination study of the genus has reported brood-site pollination by thrips in M. hullettii. In this study, the pollination system of Macaranga tanarius is reported. METHODS The study was conducted on Okinawa and Amami Islands, Japan. Flower visitors on M. tanarius we...

The cassava (Manihot esculenta Crantz) crop is relevant for human livelihoods, particularly in poorer regions. It consumed fresh or as industrialized flour, and the roots aerial parts are also used to feed livestock. Pests may limit production, which endanger food security due socioeconomic importance of crop. Reports occurrence three insect guilds, lace bugs, shoot flies, whiteflies have been ...

The concept of the previously monogeneric subfamily Pseudocetherinae (Hemiptera: Heteroptera: Reduviidae) is revised and expanded. We here transfer Gerbelius Distant, 1903, Kayanocoris Miller, 1954, Microvarus Jeannel, 1917, Paragerbelius 1958, Voconia Stål, 1866 from Reduviinae to treat Kayanocoris, Microvarus, Paragerbelius, Pseudocethera Villiers, 1963 as junior synonyms Voconia, resulting i...
