| thysanoptera (thrips) within citrus orchards in florida: species distribution, relative and seasonal abundance within trees, and species on vines and ground cover plants. | seven citrus orchards on reduced to no pesticide spray programs were sampled for thysanoptera in central and south central florida. inner and outer canopy leaves, fruits, twigs, trunk scrapings, vines and ground cover plants were sampled monthly between january 1995 and january 1996. thirty-six species of thrips were identified from 2,979 specimens collected from within citrus tree canopies and 18,266 specimens from vines and ground cover plants within the seven citrus orchards. the thrips speci ... | 2006 | 20233100 |
| comparisons of developmental and reproductive biology between parthenogenetic and sexual echinothrips americanus (thysanoptera: thripidae). | echinothrips americanus morgan, an invasive pest on various ornamentals and greenhouse crops, was introduced into mainland china recently, posing a potential threat to ornamentals and greenhouse crops. it exhibits two different reproductive modes: arrhenotokous parthenogenesis and sexual reproduction. laboratory studies were conducted to compare the developmental and reproductive biology of e. americanus in these two reproductive modes. results showed that the oviposition period, and longevity o ... | 2012 | 22732630 |
| post-mating interactions and their effects on fitness of female and male echinothrips americanus (thysanoptera: thripidae), a new insect pest in china. | post-mating, sexual interactions of opposite sexes differ considerably in different organisms. post-mating interactions such as re-mating behavior and male harassment can affect the fitness of both sexes. echinothrips americanus is a new insect pest in mainland china, and little is known about its post-mating interactions. in this study, we observed re-mating frequency and male harassment frequency and their effects on fitness parameters and offspring sex ratios of e. americanus females. further ... | 2014 | 24489956 |
| sternal gland structures in males of bean flower thrips, megalurothrips sjostedti, and poinsettia thrips, echinothrips americanus, in comparison with those of western flower thrips, frankliniella occidentalis (thysanoptera: thripidae). | sternal pores are important features for identification of male thrips, especially within the subfamily thripinae. they vary in shape, size and distribution even between species of one genus. their functional role is speculated to be that of sex- and/or aggregation pheromone production. yet, sexual aggregations are not reported in echinothrips americanus, known to have sternal pores, while we observed aggregations in megalurothrips sjostedti, previously reported to lack them. we examined the ste ... | 2015 | 26215363 |
| male pheromones influence the mating behavior of echinothrips americanus. | two dibasic esters, the dimethyl ester of hexanedioic acid (dimethyl adipate, dbe-6) and the dimethyl ester of pentanedioic acid (dimethyl glutarate, dbe-5) were found in head-thorax extracts of male echinothrips americanus. dbe-5 induced abdomen wagging and raising in males and females, which is typically exhibited when encountering a male. dbe-6 was avoided by males and was detected on mated, but not on virgin, females. both substances applied to virgin females lead to females being ignored by ... | 2016 | 27008648 |
| genomovirus genomes recovered from echinothrips americanus sampled in florida, usa. | four genomovirus genomes were recovered from thrips (echinothrips americanus) collected in florida, usa. these represent four new species which are members of the gemycircularvirus (n = 2), gemyduguivirus (n = 1), and gemykibivirus (n = 1) genera. this is the first record, to our knowledge, of genomoviruses associated with a phytophagous insect. | 2017 | 28546499 |
| reproductive behavior of echinothrips americanus (thysanoptera: thripidae). | most thysanoptera possess a haplo-diploid reproductive mode and reproduce via arrhenotoky. females can mature eggs successively throughout almost their entire life, but in most terebrantian thrips spermiogenesis is complete by adult male eclosion, and testes contain only mature spermatids. in parasitoid wasps this phenomenon of preadult spermiogenesis is described as prospermatogeny. it is unclear if prospermatogeny and this predetermined sperm quantity have implications for mating strategy and ... | 2017 | 28931160 |
| biological control of echinothrips americanus by phytoseiid predatory mites and the effect of pollen as supplemental food. | the poinsettia thrips, echinothrips americanus morgan, is an upcoming pest in greenhouse crops, causing serious damage in various vegetable and ornamental crops through extensive foliage feeding. we assessed which stages of e. americanus are attacked and killed by the phytoseiid predatory mites amblyseius swirskii (athias-henriot), amblydromalus limonicus (garman and mcgregor), euseius gallicus kreiter and tixier and euseius ovalis (evans). both the predation and oviposition rates were assessed ... | 2017 | 29128983 |
| first detection of wolbachia in arrhenotokous populations of thrips species (thysanoptera: thripidae and phlaeothripidae) and its role in reproduction. | insects in the order thysanoptera are known for their haplodiploid reproduction, with most species reproducing by arrhenotoky. a few species, however, have only female populations and reproduce by thelytoky. seven thrips species reproducing either by arrhenotoky [frankliniella occidentalis (pergande), echinothrips americanus morgan, suocerathrips linguis mound and marullo, gynaikothrips ficorum (marchal)] or thelytoky [hercinothrips femoralis (o.m. reuter) and parthenothrips dracaenae (heeger)] ... | 2008 | 19161685 |
