“…While these predators have been recorded feeding on insect eggs (Ewing & Ivy, 1943;Lingren et al, 1968) they seem to prefer live, mobile prey (Ables, 1978;pers. Because these two reduviid species are not abundant, have slow development times, low reproductive rates, and long prey handling times they probably have little effect on whitefly or pink bollworm populations (Swadener & Yonke 1973a, b;Ali & Watson, 1978). Therefore a positive response for either pest is likely due to feeding on adult females.…”

The gut contents of field-collected, predaceous Heteroptera were assayed for the presence of eggs of the sweetpotato whitefly, Bemisia tabaci Gennadius (Homoptera: Aleyrodidae) and the pink bollworm, Pectinophora gossypiella (Saunders) (Lepidoptera: Gelechiidae) using multiple enzyme-linked immunosorbent assays (ELISAs). Of seven species examined, Geocoris species and Orius tristicolor (Say) were the most frequent predators of sweetpotato whitefly with 32-39% of the individuals tested over the whole season scoring positive for whitefly antigens. With the exception of Lygus hesperus Knight, a major insect pest as well as a predator, the frequency of predation on pink bollworm eggs was much lower (0.7-14.3% positive over the season). Relatively few predators tested positive for both antigens (0.3-12.5%).

“…Species of Zelus , among several other genera (e.g., Arilus Hahn, Sinea Amyot & Serville, and Montina Amyot & Serville), have been explored and studied as natural enemies in the Americas (Cohen and Tang 1997, Cogni et al 2002). Species of Zelus prey on a wide range of insects in cotton, corn, soybean, alfalfa crops and fruit trees in California and elsewhere (Ali and Watson 1978, McPherson et al 1982, Cisneros and Rosenheim 1998, Virla et al 2015), may reach population densities of up to 50,000 to 75,000/ha, and prevent outbreaks of lepidopteran larvae (Ables 1978). Hart (1972) conducted a taxonomic revision of Zelus with descriptions of twenty-five new species and twenty-six new synonyms, most of which remained unpublished (see Hart 1986, Hart 1987 for treatments of twenty Canadian, US, northern Mexican and Caribbean species).…”

The New World assassin bug genus Zelus Fabricius, 1803 (Insecta: Hemiptera: Heteroptera: Reduviidae: Harpactorinae: Harpactorini) is revised based on more than 10,000 specimens. Seventy-one species are recognized and twenty-four described as new: Zelus aithaleos sp. n., Zelus amblycephalus sp. n., Zelus antiguensis sp. n., Zelus auralanus sp. n., Zelus bahiaensis sp. n., Zelus banksi sp. n., Zelus casii sp. n., Zelus championi sp. n., Zelus cordazulus sp. n., Zelus fuliginatus sp. n., Zelus gilboventris sp. n., Zelus gracilipes sp. n., Zelus grandoculus sp. n., Zelus kartaboides sp. n., Zelus lewisi sp. n., Zelus panamensis sp. n., Zelus paracephalus sp. n., Zelus rosulentus sp. n., Zelus russulumus sp. n., Zelus spatulosus sp. n., Zelus truxali sp. n., Zelus umbraculoides sp. n., Zelus umbraculus sp. n., and Zelus xouthos sp. n. Five species, Zelus araneiformis Haviland, 1931, Zelus gradarius Bergroth, 1905, Zelus modestus (Stål, 1862), Zelus subfasciatus Stål, 1860 and Zelus vittaticeps Stål, 1866, are removed from Zelus and placed incertae sedis within Harpactorini. Nine new synonyms are recognized (senior synonym in parentheses): Zelus atripes Champion, 1898 syn. nov. (=Zelus conjungens [Stål, 1860]), Zelus dispar Fabricius, 1803 syn. nov. (=Zelus pedestris Fabricius, 1803), Zelus formosus Haviland, 1931 syn. nov. (=Zelus laticornis Herrich-Schaeffer, 1853), Zelus obscuridorsis (Stål, 1860) syn. nov. (=Zelus pedestris), Zelus pallidinervus Haviland, 1931 syn. nov. (=Zelus kartabensis Haviland, 1931), Zelus personatus Berg, 1879 syn. nov. (=Zelus versicolor Herrich-Schaeffer, 1848), Zelus trimaculatus Champion, 1898 syn. nov. (=Zelus means Fabricius, 1803), Zelus trimaculicollis (Stål, 1855) syn. nov. (=Zelus means), and Zelus tristis Haviland, 1931 syn. nov. (=Zelus laticornis). Zelus conjungens (Stål, 1860) stat. rev. Is resurrected from junior synonymy with zealous armillatus (Lepeletier & Seville, 1825). Zelus ambulans Stål, 1862 stat. rev. and Zelus cognatus (Costa, 1862) stat. rev. are resurrected from synonymy with Zelus exsanguis Stål, 1862. Iquitozelus Bérenger syn. nov. is synonymized with Zelus and its only species transferred to Zelus, hence resulting in a new combination, Zelus couturieri (Bérenger, 2003) comb. nov. Lectotypes, paralectotypes or neotypes are designated for a number of species. Habitus images, illustrations of male genitalia, distribution maps and measurements are provided for nearly all species. The three previously recognized subgenera of Zelus are found to be based upon superficial characters and these divisions do not reflect natural groupings. Using sets of characters, especially those of the male genitalia, eleven species groups are proposed. It is also hypothesized that Zelus is closely related to three other New World genera: Atopozelus Elkins, Ischnoclopius Stål and an undescribed genus "Hartzelus" [manuscript name]. Zelus is endemic to the New World, occurring naturally in the Caribbean and all but one of the continental countries, with introductions to Pacific islands, E...

“…Though substrata did not influence the incubation period, the stadial periods of nymphal instars of R. marginatus reared on dry litter with strip and green leave with stem were greatly shortened over three categories. Debach and Hagen (1964), Watson (1964), Ali and Watson (1978), Braman et al (1984) and Whitcomb (1994) pointed out that developmental duration of predators prolonged when their abiotic factors were varied. Moreover, Eigenbrode et al (1996) stated that the developmental period prolonged when sensillae of tarsi of anthocorid Orius insidiosus (Say) were damaged or coated with debris while working on polished surface or wax layered plants.…”

The present research project was conducted to study the effects of varied substrata on the development of R. marginatus. Rhynocoris marginatus was mass reared on five different substrata viz., untreated plastic, tissue and glutting papers, sand and stone, litter and strip, and green leave and stem. The stadial periods of nymphal instars of R. marginatus reared on dry litter with strip ad green leaves with stem were greatly shortened over plastic, tissue and glutting papers, and sand with stone substrata. Green leaves with stem supported better survival than substrata such as plastic, sand with stone, tissue and glutting papers and dry litter with strip. Preoviposition period was shortened in the green leaves with stem and tissue and glutting papers substrata. The fresh adult body weights were slightly higher for R. marginatus reared on four varied substrata than those reared on untreated plastic substrata. Significantly the highest fecundity was found in the green leaves with stem substrate category.
