“…Among the key pests, the sucking insects thrips (Thysanoptera: Thripidae), Aphis gossypii Glover (Hemiptera: Aphididae) and Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) are responsible for the greatest losses . Many thrips species have been reported in watermelon, where Thrips tabaci Lindeman, Thrips palmi Karny and Frankliniella schultzei Trybom are considered the most important . Thrips cause direct and indirect damage to plants.…”

“…As ordens Hymenoptera, Diptera e Coleoptera foram as mais representativas com abundancias relativas de 91,68%, 4,31% e 2,98%, respectivamente (Tabela 1). As ordens detectadas no presente levantamento estão entre as principais ordens de importância agrícola, sendo a maioria comumente encontrada em estudos entomofaunísticos realizados em outras culturas (SILVA; CARVALHO, 2000;GRUTZMACHER;LINK, 2000;GALLO et al, 2002;RAMIRO;FARIA, 2006;ZALAZAR;SALVO, 2007;AZEVEDO;MARQUES, 2008;BERNARDI et al, 2010;WALKER et al, 2010;GOMES et al, 2012;COSTA et al, 2014;COSTA et al, 2014;COSTA et al, 2015;COSTA et al, 2016).…”

O objetivo do trabalho foi avaliar a diversidade de insetos em área de policultivo e monocultivo agroecológico de frutíferas no município de Ipanguaçu, Rio Grande do Norte. O levantamento foi realizado na fazenda escola do Instituto Federal do Rio Grande do Norte (IFRN), Campus Ipanguaçu, no período de junho à agosto de 2012, em duas áreas distintas (0,8 ha cada): Área 1 (5°32'14.86"S e 36°52'19.81"W) - Pomar agroecológico (policultivo com goiaba, acerola, graviola, limão, manga e banana) e Área 2 (5°32'1.55"S 36°53'2.21"W) - monocultivo agroecológico de banana. Foram identificadas ao final do levantamento nove ordens na área de policultivo agroecológico de frutíferas: Hymenoptera, Diptera, Coleoptera, Orthoptera, Blattodea, Hemiptera, Lepidoptera, Odonata e Dermaptera e quatro na área com monocultivo agroecológico de banana: Hymenoptera, Diptera, Coleoptera e Orthoptera. O resultado obtido no presente trabalho indica que, mesmo sob o mesmo sistema de manejo, em áreas cultivadas com mais de uma espécie frutífera ocorre à presença de uma maior diversidade de insetos. Primary inventory of entomofauna in polyculture and monoculture fruit trees areas in municipality of Ipanguaçu, RNAbstract: This study aimed to evaluate the insect diversity in polyculture and monoculture agroecological of fruit trees in municipality of Ipanguaçu, Rio Grande do Norte. The survey was carried out at the experimental farm of the Federal Institute of Rio Grande do Norte, Campus Ipanguaçu, in period from June to August 2012, in two distinct areas (0.8 ha each): Area 1 (5°32'14.86"S e 36°52'19.81"W) - Agroecological orchard (polyculture with guava, acerola, graviola, lemon, mango and banana) and 2 (5°32'1.55"S 36°53'2.21"W) – Banana’s agroecological monoculture. At the end of the survey, nine orders were identified in area of fruit trees’s agroecological polyculture: Hymenoptera, Diptera, Coleoptera, Orthoptera, Blattodea, Hemiptera, Lepidoptera, Odonata e Dermaptera e quatro na área com monocultivo agroecológico de banana: Hymenoptera, Diptera, Coleoptera e Orthoptera. The results obtained in the present study indicate that even under the same management system, in areas cultivated with more than one fruit species, the presence of a greater diversity of insects occurs.

“…An economic crop like groundnut hosts both T. palmi and S. dorsalis [24]. More than one thrips vector is also reported in tomato [25], watermelon [26], and soybean [27]. Therefore, development of appropriate methods for fast and concurrent identification of these thrips vectors at an early stage of infestation seems to be essential, especially when they are minute and cryptic in nature and spreading diseases [11,12,28].…”

A multiplex PCR assay for rapid identification of major tospovirus vectors reported in India

et al. 2020

Background: To date, four thrips vectors have been reported to transmit five different tospoviruses in India. Their identification at an early stage is crucial in formulating appropriate pest management strategies. Since morphometric key-based thrips identification based on the adult stage is time-consuming, there is a need to develop diagnostic tools which are rapid, accurate, and independent of developmental stages. Here, we report a multiplex PCR assay to identify four major thrips vectors viz. Thrips palmi, T. tabaci, Scirtothrips dorsalis, and Frankliniella schultzei present in India. Results: Cytochrome oxidase subunit III and internal transcribed spacer region 2 were utilized to design speciesspecific primers. Of 38 pairs of primers tested, primer pairs AG35F-AG36R, AG47F-AG48R, AG87F-AG88R, and AG79F-AG80R amplified 568 bp, 713 bp, 388 bp, and 200 bp products from the DNA templates of T. palmi, S. dorsalis, T. tabaci, and F. schultzei, respectively at same PCR conditions. The specificity of the primer pairs was validated with a large number of known specimens and no cross-reactivity was observed with other thrips species. The multiplex PCR assay with a cocktail of all the four primer pairs detected four thrips vectors efficiently and could discriminate all of them concurrently in a single reaction. Conclusion: The multiplex PCR reported in this study could identify the major thrips vectors reported in India. The assay will be useful in ascertaining distribution profile of major thrips vectors, disease epidemiology, screening large samples, and quarantine.
