A complex of hemipterans, especially the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois) (Hemiptera: Miridae), has become a major target of insecticides in flowering cotton, Gossypium hirsutum L., in the mid-southern United States. Sampling protocols for this complex during this period of cotton development are poorly established, resulting in uncertainty about when infestations war...

Compsidolon Reuter from China with eleven species is reviewed here. Three of them, C. ailaoshanensis, C. flavidum, and C. pilosum are described as new to science. C. eximium (Reuter) is recorded from China for the first time. Compsidolon punctulatum Qi and Nonnaizab, 1995 is treated as a junior synonym of Compsidolon nebulosum (Reuter, 1878). A key to Chinese species of Compsidolon Reuter is gi...

Within the genus Macrolophus (Heteroptera: Miridae), the species M. costalis (Fieber), M. melanotoma (Costa) and M. pygmaeus (Rambur) are present in the Mediterranean region on a wide variety of plant species. While M. costalis can easily be separated from the other two by the black tip at the scutellum, M. pygmaeus and M. melanotoma are cryptic species, extremely similar to one another in exte...

Lygus hesperus Knight (Hemiptera: Miridae) is a key pest of cotton (Gossypium spp.) in the western United States that injures ßoral buds (squares) and developing fruit (bolls). Levels of Lygus-induced damage to cotton can vary by Lygus ages or gender, and these variations complicate interpretation of studies designed to elucidate Lygus and cotton interactions. Variations in observed injury may ...

Alfalfa (Medicago sativa L.) is a highly attractive plant host to Lygus spp. and is used as a trap crop in California organic strawberries to influence the dispersion and dispersal of these pests, particularly Lygus hesperus Knight. The abundance and distribution of Lygus spp. nymphs between two trap crops separated by 50 strawberry rows was analyzed in 2008 and 2010. Nymphs demonstrated a bimo...

A new species of the genus Sulawesifulvius, Sulawesifulvius thailandicus Wolski, Yasunaga & Gorczyca, sp. n., is described from Thailand. The present finding also represents the first distribution record in Indochina for the genus. Color adult habitus images for Sulawesifulvius thailandicus and Sulawesifulvius schuhi (type species of the genus), male genital drawings of Sulawesifulvius thailand...

The unique genus Biromiris Schuh is recognized from the Oriental region for the first time, with the description of a new species, Biromiris tomokuniisp. n., from the Philippines. The new species is documented with photographic images of the dorsal habitus and male genital structures. A key to all known species of Biromiris is provided.

Five new species of Hypseloecus viz., Hypseloecus acutus sp. nov., Hypseloecus articulatus sp. nov., Hypseloecus belli sp. nov., Hypseloecus orientale sp. nov. and Hypseloecus spinosus sp. nov. are described from India. The genus is recorded for the first time from India collected on hemiparasitic plants of the genera Dendrophthoe and Viscum (Santalales). A key to identification of the five spe...

The tarnished plant bug, Lygus lineolaris (Palisot de Beauvois) (Hemiptera: Miridae), has become the primary target of foliar insecticides in cotton, Gossypium hirsutum L., throughout the Midsouth over the past several years. This prompted a reevaluation of existing action thresholds for flowering cotton under current production practices and economics. A trial was conducted at 19 locations thr...
