| understanding trophic interactions of orius spp. (hemiptera: anthocoridae) in lettuce crops by molecular methods. | the aphid nasonovia ribisnigri (mosley) (hemiptera: aphididae) and the thrips frankliniella occidentalis (pergande) (thysanoptera: thripidae) are common pests in mediterranean lettuce crops, where orius spp. are common generalist predators. predation by orius spp. was studied in a lettuce plot by conventional polymerase chain reaction (pcr) and real-time pcr analyses using specific primers of both main pests. also, high-throughput sequencing was used to have a wider approach of the diet of these ... | 2016 | 25641943 |
| efficacy of commercially available invertebrate predators against drosophila suzukii. | drosophila suzukii has been recorded in the uk since the end of 2012. to date, reports of serious damage have been rare. previous research has demonstrated that there are chemicals available within the uk that are efficient in dealing with d. suzukii. however, few effective chemicals for use by the organic sector have been identified; equally the addition of "new" insecticides into previously stable ecosystems can have negative impacts upon natural enemies and so disrupt control strategies that ... | 2014 | 26462951 |
| true bugs (hemiptera, heteroptera) as psyllid predators (hemiptera, psylloidea). | data on natural enemies of psyllids are rare and can usually be found in papers about economically significant species. during an investigation of psyllid fauna in serbia, natural enemies were investigated, too. true bugs were the most numerous among them. from 28 psyllid species, 21 species of true bugs from families anthocoridae and miridae were reared. seven species of anthocoridae were identified: anthocoris amplicollis (horváth, 1839), anthocoris confusus reuter, 1884, anthocoris nemoralis ... | 2013 | 24003311 |
| innate and learned prey-searching behavior in a generalist predator. | early colonization by zyginidia scutellaris leafhoppers might be a key factor in the attraction and settling of generalist predators, such as orius spp., in maize fields. in this paper, we aimed to determine whether our observations of early season increases in field populations of orius spp. reflect a specific attraction to z. scutellaris-induced maize volatiles, and how the responses of orius predators to herbivore-induced volatiles (hipvs) might be affected by previous experiences on plants i ... | 2016 | 27343054 |
| effect of nymphal diet on adult predation behavior in orius majusculus (heteroptera: anthocoridae). | the predatory bug orius majusculus (reuter) was reared on 2 different diets during the nymphal stages. the 1st group was exclusively offered eggs of ephestia kuehniella zeller (lepidoptera: pyralidae), a standard diet for o. majusculus production. the 2nd group was exclusively offered 4th instars of the pea aphid, acyrtosiphon pisum (harris). subsequently, adult predatory behavior in experimental arenas containing a. pisium was recorded using 2 video cameras. one camera permitted observation of ... | 2000 | 10826169 |
| human-biting potential of the predatory flower bug orius majusculus (hemiptera: anthocoridae). | the targeted biting of, and feeding on, humans by orius majusculus, a flower bug predating on arthropods, is reported. although the observed incidents certainly do not represent the normal feeding behaviour of the bug species, o. majusculus should be kept in mind as one option when insect bites during summer time are to be analysed. | 2011 | 21229264 |
