BACKGROUND AND AIMS Unlike other taxa in Juglandaceae or in closely related families, which are anemophilous, Platycarya strobilacea has been suggested to be entomophilous. In Juglandaceae, Juglans and Carya show heterodichogamy, a reproductive strategy in which two morphs coexist in a population and undergo synchronous reciprocal sex changes. However, there has been no study focusing on hetero...

ducted with modern cotton cultivars (Touchton et al., 1984; Bauer et al., 1993; Daniel et al., 1999; Larson et Thrips, primarily Frankliniella spp., can damage cotton (Gossypal., 2001). Grass cover crop residues generally have a ium hirsutum L.) seedlings. The objectives of this study were to determine the effect of winter cover crops on thrips populations in high C/N ratio, which causes N immo...

abstract-the species frankliniella occidentalis (pergande),western flower thrips, is a highly polyphagous pest and an important vector of tospoviruses on several crops and ornamental plants. western flower thrips has been introduced throughout the world and has been subject to many biological studies including mass rearing. in this survey, seven common mass rearing methods of f. occidentalis we...

Tomato spotted wilt virus (TSWV) and other closely related tospoviruses are serious threats to many agricultural, ornamental, and greenhouse crops. TSWV was first recorded in the southeastern United States during the middle to late 1980's with the first collections of the western flower thrips, Frankliniella occidentalis Pergande, following shortly thereafter. In North Carolina, TSWV was first ...

The purpose of the study was to identify forage plants and specialized entomophages wheat thrips in agrocenoses winter spring grain crops cultivated Samara region. highest number adult pests noted (2365.0 ind./100 strokes), lowest barley (565.0 strokes). Egg laying by thrip females occurred on all crops. Larvae were ears wheat, triticale, barley, with exception barley. During research, two iden...

It has been shown that many insects have Enterobacteriaceae bacteria in their gut system. The western flower thrips, Frankliniella occidentalis Pergande [Thysanoptera: Thripidae], has a symbiotic relation with Erwinia species gut bacteria. To determine if other Thripidae species have similar bacterial symbionts, the onion thrips, Thrips tabaci, was studied because, like F. occidentalis, it is p...

During November 2021, a new invasive thrips Thrips parvispinus was recorded in chilli growing areas of Telangana state. In India, this pest first reported on papaya (Carica L.) and later Brugmansia sp. (Solanaceae) Dahlia rosea Cav. (Asteraceae). Based these reports alert received from ICAR-NBAIR, Bengaluru, survey carried out major Anand district Gujarat Incidence T. noticed during the survey....

Sexual dimorphism is a phenotypic differentiation between males and females of the same species. Thrips display a wide variety of sexual dimorphism between taxa including size, ornamentation and coloration (Crespi 1986, Mound 2005, Tyagi et al. 2008). During recent surveys on the thrips fauna in subtropical China, Aroidothrips longistylus Ananthakrishnan, an interesting and little known sexuall...

The thrips Scirtothrips dorsalis Hood (Thysanoptera: Thripidae) is an invasive pest that poses a significant economical threat to U.S. agriculture and trade. In this study, DNA sequence data and polymerase chain reaction (PCR) were utilized to develop a molecular diagnostic marker for S. dorsalis. The DNA sequence variation from the internal transcribed spacer 2 (ITS2) region of nuclear ribosom...
