| role of mites and thrips in the agrobiocoenosis of the soybean. | soy beans dangerous pests are mites and thrips, that is why the present paper aims at the examination of the changes in their numbers and dominance relations of some varieties of different maturity groups. the small plot experiments were conducted in kisalföld region with the following soybean varieties: early ripening bólyi 38, evans, mccall, middle ripening bólyi 45 and late ripening eszter, zsuzsanna and borza, in mosonmagyaróvár. mites and thrips were collected every week with berlese-extrac ... | 2003 | 15149112 |
| population dynamics of banded thrips (aeolothrips intermedius bagnall, thysanoptera, aeolothripidae) and its potential prey thysanoptera species on white clover. | in 2002, the occurrence of banded thrips (aeolothrips intermedius bagnall) and some other thysanoptera species on white clover (trifolium repens l.) was monitored at two locations in the continental part of slovenia. white clover presents in many countries important intercrop in integrated vegetable production. light blue sticky boards were placed on grasslands (one parcel on each location) with high percentage of white clover. sticky boards were changed in about 10-days intervals from the end o ... | 2005 | 16628913 |
| the occurrence and species composition of thrips (thysanoptera) on onion. | the aim of the present research work was to investigate the population density and species composition of thrips infesting crops of onion in south poland. the flight activity of thrips was monitored using blue sticky traps and plant samples were taken to record the number of adult and larvae of thrips on onion. in 2004 the thrips were caught into blue sticky traps from the start of june to the end of the first decade of september. the peak flight activity was noticed in the middle of july. in 20 ... | 2007 | 18399478 |
| intra- and interspecific molecular polymorphism of thrips species. | molecular polymorphism of six species of thysanoptera of both sexes, collected from different locations and host plants in hungary was studied by using rapd-pcr technique. the specimens were classified according to sampling sites (gödöllö, nagykovácsi and valkó), host plants (lathyrus tuberosus, medicago sativa, taraxacum officinale, trifolium pratense), sexes, and larvae in case of aeolothrips intermedius. on the basis of the total of 103 fragments generated by 15 rapd primers the genetic dista ... | 2002 | 12371611 |
| the ultrastructure of malpighian tubules and the chemical composition of the cocoon of aeolothrips intermedius bagnall (thysanoptera). | the secretory activity of the two branched malpighian tubules (mts) of the second-instar larva in aeolothrips intermedius is described. mts of adult thrips have the typical ultrastructure of excretory epithelium with apical microvilli containing long mitochondria and a rich system of basal membrane infoldings. in the second-instar larva just before pupation, the ultrastructure of mt epithelial cells is dramatically different, and there are numerous huge golgi systems in the cytoplasm. these cell ... | 2010 | 19725134 |
| the spermatogenesis and the sperm structure of terebrantia (thysanoptera, insecta). | spermatogenesis and the sperm structure of the terebrantian aeolothrips intermedius bagnall are described. spermatogenesis consists of two mitotic divisions; the second is characterized by the loss of half of the spermatids, which have pyknotic nuclei. early spermatids have two centrioles, but when spermiogenesis starts, a third centriole is produced. the three basal bodies give rise to three flagella; later these fuse into a single flagellum which contains three 9+0 axonemes. the basal bodies a ... | 2010 | 20542530 |
| dna barcode analysis of thrips (thysanoptera) diversity in pakistan reveals cryptic species complexes. | although thrips are globally important crop pests and vectors of viral disease, species identifications are difficult because of their small size and inconspicuous morphological differences. sequence variation in the mitochondrial coi-5' (dna barcode) region has proven effective for the identification of species in many groups of insect pests. we analyzed barcode sequence variation among 471 thrips from various plant hosts in north-central pakistan. the barcode index number (bin) system assigned ... | 2016 | 26741134 |
