| morphology and volatile compounds of metathoracic scent gland in tessaratoma papillosa (drury) (hemiptera: tessaratomidae). | tessaratoma papillosa (drury) (hemiptera: tessaratomidae) is a serious insect pest of litchi and longan in south china. when disturbed, this insect could release large quantities of disagreeable odorous volatiles from its scent gland. knowledge on the scent gland and its secretion is crucial for developing the semiochemical methods to manage this pest. morphology and ultrastructure of the metathoracic scent glands (mtgs) were studied under stereo and scanning electron microscopy, and the volatil ... | 2012 | 23950062 |
| the isolation and identification of pathogenic fungi from tessaratoma papillosa drury (hemiptera: tessaratomidae). | litchi stink-bug, tessaratoma papillosa drury (hemiptera: tessaratomidae), is one of the most widespread and destructive pest species on litchi chinensis sonn and dimocarpus longan lour in southern china. inappropriate use of chemical pesticides has resulted in serious environmental problems and food pollution. generating an improved integrated pest management (ipm) strategy for litchi stink-bug in orchard farming requires development of an effective biological control agent. entomopathogenic fu ... | 2017 | 29018621 |
| transcriptome sequencing of tessaratoma papillosa antennae to identify and analyze expression patterns of putative olfaction genes. | studies on insect olfaction have increased our understanding of insect's chemosensory system and chemical ecology, and have improved pest control strategies based on insect behavior. in this study, we assembled the antennal transcriptomes of the lychee giant stink bug, tessaratoma papillosa, by using next generation sequencing to identify the major olfaction gene families in this species. in total, 59 odorant receptors, 14 ionotropic receptors (8 antennal irs), and 33 odorant binding proteins (2 ... | 2017 | 28596537 |
| scanning electron microscopy studies of antennal sensilla of ooencyrtus phongi (hymenoptera: encyrtidae). | ooencyrtus phongi (hymenoptera: encyrtidae) is an important egg parasitoid of the litchi stink bug, tessaratoma papillosa (drury) (hemiptera: tessaratomidae). antennae of parasitic hymenoptera are important sensory organs and play an important role in host location, host discrimination, courtship, and mating behavior. in this article, we examined the external morphology of the antennal sensilla of female and male of o. phongi using scanning electron microscopy. twelve morphological sensillar typ ... | 2011 | 21413102 |
| molecular basis of peripheral olfactory sensing during oviposition in the behavior of the parasitic wasp anastatus japonicus. | anastatus japonicus is a parasitic wasp and natural enemy of the litchi pest tessaratoma papillosa, and for decades in china, a. japonicus has been mass-reared inside the eggs of antheraea pernyi to control t. papillosa. a series of experiments was performed to explore the olfactory mechanism underlying the oviposition behavior of a. japonicus. first, a transcriptomic analysis was performed on the antennae of a. japonicus, and the resulting assemblies led to the generation of 70,473 unigenes. su ... | 2017 | 28912112 |
| study of the alarming volatile characteristics of tessaratoma papillosa using spme-gc-ms. | the stinkbug's volatile compositions would alter very much before and after stinkbugs were disturbed or irritated, which caused the alarming effect. an efficient headspace solid-phase microextraction sampling method was established to study the alarming volatile characteristics and potential alarming volatiles of stinkbugs (tessaratoma papillosa) followed by gas chromatography-mass spectrometry detection. the number of volatiles identified was 16 and 22 before and after stinkbug irritation, resp ... | 2009 | 19406015 |
| [roles of infochemicals in host-selection process of anastatus japonicus]. | by using a y-tube olfactometer, this paper studied the selection behavior's responses of anastatus japonicus to the volatiles and their individual components emitted from isolated leaves and live plants of different litchi varieties, and to tessaratoma papillosa. the results showed that among the test litchi varieties, sanyuehong and huaizhi had more significant attracting effects to a. japonicus than nuomici, guiwei, feizixiao and heiye. the two main components of the volatiles from litchi leav ... | 2007 | 17615886 |
