| bionomics of the anthocoridae. | the family anthocoridae (hemiptera:heteroptera) contains between 400 and 600 species distributed worldwide, chiefly on the continents but also on oceanic islands. they are small (1.4-4.5 mm) and common to a wide variety of habitats. many are found in cryptic habitats such as galls, several widespread genera are surface feeders on small arthropods (anthocoris, orius, and tetraphleps), and others can be found in ant nests and, especially, under bark. wing polymorphism is common in this family, oft ... | 1999 | 15012372 |
| foraging behavior and prey interactions by a guild of predators on various lifestages of bemisia tabaci. | the sweetpotato whitefly, bemisia tabaci (gennadius) is fed on by a wide variety of generalist predators, but there is little information on these predator-prey interactions. a laboratory investigation was conducted to quantify the foraging behavior of the adults of five common whitefly predators presented with a surfeit of whitefly eggs, nymphs, and adults. the beetles, hippodamia convergens guerin-meneville and collops vittatus (say) fed mostly on whitefly eggs, but readily and rapidly preyed ... | 2004 | 15861217 |
| conservation of natural enemies in cotton: comparative selectivity of acetamiprid in the management of bemisia tabaci. | the integrated control concept emphasizes the importance of both chemical and biological control for pest suppression in agricultural systems. a two-year field study was conducted to evaluate the selectivity of acetamiprid for the control of bemisia tabaci (gennadius) in cotton compared with a proven selective regime based on the insect growth regulators (igrs) pyriproxyfen and buprofezin. acetamiprid was highly effective in controlling all stages of b tabaci compared with an untreated control, ... | 2005 | 15712368 |
| conservation of predatory arthropods in cotton: role of action thresholds for bemisia tabaci (homoptera: aleyrodidae). | studies were conducted in 1994 and 1995 to examine the effects of a range of action thresholds for managing bemisia tabaci (gennadius) biotype b (= b. argentifolii bellows & perring) with insecticides in cotton on populations of arthropod predators in imperial valley, ca, and maricopa, az. application of insecticides significantly reduced population densities of spiders, geocoris punctipes (say), g. pallens (stål), orius tristicolor (white), nabis alternatus parshley, zelus renardii kolenati, hi ... | 2002 | 12216807 |
| natural enemies of the frankliniella complex species (thysanoptera: thripidae) in ataulfo mango agroecosystems. | a field survey was conducted in ataulfo mango (mangifera indica l.) orchards in chiapas, mexico, with the objective of determining the natural enemies of the frankliniella complex species (thysanoptera: thripidae). seven species of this genus feed and reproduce in large numbers during the mango flowering. two representative orchards were selected: the orchard "tres a" characterized by an intensive use of agrochemicals directed against thrips, and the orchard "la escondida" that did not spray ins ... | 2015 | 26246440 |
| field-testing of methyl salicylate for recruitment and retention of beneficial insects in grapes and hops. | evidence for recruitment and retention of beneficial insects in grapes and hops using controlled-release dispensers of methyl salicylate (mesa), a component of herbivore-induced volatile blends, is presented. in a replicated experiment conducted in a juice grape vineyard, sticky cards in blocks baited with mesa captured significantly greater numbers of five species of predatory insects (chrysopa nigricornis, hemerobius sp., deraeocoris brevis, stethorus punctum picipes, orius tristicolor) than u ... | 2004 | 15537163 |
| identification and impact of natural enemies of bactericera cockerelli (hemiptera: triozidae) in southern california. | bactericera cockerelli (sulc) (hemiptera: triozidae) is a major pest of potato, (solanum tuberosum l.), tomato (solanum lycopersicum l.), and peppers (capsicum spp.). the purpose of our research was to identify and determine the impact of natural enemies on b. cockerelli population dynamics. through 2 yr of field studies (2009-2010) at four different sites and laboratory feeding tests, we identified minute pirate bug, orius tristicolor (white) (hemiptera: anthocoridae); western bigeyed bug, geoc ... | 2012 | 23156144 |
| effect of buprofezin on survival of immature stages of harmonia axyridis, stethorus punctum picipes (coleoptera: coccinellidae), orius tristicolor (hemiptera: anthocoridae), and geocoris spp. (hemiptera: geocoridae). | the effect of buprofezin, a chitin synthesis inhibitor, on development and survival of immature stages of harmonia axyridis (pallas), stethortus punctum picipes casey, orius tristicolor (white), geocoris pallens stål, and geocoris punctipes (say), was examined in a series of laboratory bioassays. very few h. axyridis larvae (3.1%) treated with buprofezin reached adulthood, although 65% of treated pupae emerged successfully. buprofezin caused no mortality to eggs of s. punctum picipes but 71.1% o ... | 2004 | 15279269 |
| functional response of three species of predatory pirate bugs attacking eggs of tuta absoluta (lepidoptera: gelechiidae). | the functional response and predation parameters of three species of predatory pirate bugs amphiareus constrictus (stal), blaptostethus pallescens poppius, and orius tristicolor (white) (hemiptera: anthocoridae) were evaluated at four different densities of eggs of tuta absoluta (meyrick) (lepidoptera: gelechiidae). experiments were conducted in petri dishes containing a tomato leaf disk infested with the pest eggs, and maintained inside growth chamber with environmental conditions of 25 ± 2 °c, ... | 2015 | 26313178 |
| further field evaluation of synthetic herbivore-induced plant volatiles as attractants for beneficial insects. | fifteen synthetic herbivore-induced plant volatiles (hipvs) were field-tested for attractivity to beneficial insects in two experiments conducted in an open field and a hop yard in washington state. eleven insect species or families showed significant attraction to 13 hipvs. the ladybeetle, stethorus punctum picipes, was attracted to sticky traps baited with methyl salicylate (mesa), cis-3-hexen-1-ol (he), and benzaldehyde (be). the minute pirate bug, orius tristicolor, was attracted to traps ba ... | 2005 | 15898496 |
| effect of methyl salicylate-based lures on beneficial and pest arthropods in strawberry. | methyl salicylate (mesa) is a common herbivore-induced plant volatile that, when applied to crops, has the potential to enhance natural enemy abundance and pest control. the impacts of mesa in strawberry were unknown and examined in the spring and midsummer period. strawberry plots contained no lures (control) or two 30-d mesa lures (predalure) in the center: one lure 0.61 m aboveground over a sticky trap, and one lure on a plant near the ground. arthropod abundance was monitored at the point so ... | 2010 | 20388299 |
