Isolation of Microsatellite Loci from the Onion Thrips, Thrips tabaci
Thrips tabaci Lindeman (Thysanoptera: Thripidae), a cosmopolitan pest insect, is subdivided into at least three genetic lineages that have different biological characters, such as reproductive mode and resistibility to insecticides. Since the lineages are discriminated only by mitochondrial DNA, there is a possibility of gene flow among lineages at the genomic level. Nine polymorphic microsatel...
متن کاملConsequences of co-applying insecticides and fungicides for managing Thrips tabaci (Thysanoptera: Thripidae) on onion.
BACKGROUND Insecticides and fungicides are commonly co-applied in a tank mix to protect onions from onion thrips, Thrips tabaci Lindeman, and foliar pathogens. Co-applications reduce production costs, but past research shows that an insecticide's performance can be reduced when co-applied with a fungicide. An evaluation was made of the effects of co-applying spinetoram, abamectin and spirotetra...

طول دوره‌ی رشد، تولید مثل و پارامترهای جدول زندگی سه جمعیت تریپس پیاز، Thrips tabaci Lindeman، شامل خراسان رضوی و گلستان روی پیاز و مازندران روی توتون در شرایط آزمایشگاهی (دمای ٢5 درجه‌ی سانتیگراد، رطوبت نسبی 5٠ درصد و طول دوره‌ی روشنایی به تاریکی ١٦ به ۸ ساعت) مطالعه شد. طول دوره‌ی زندگی از تخم تا مرحله‌ی بلوغ در جمعیتهای خراسان رضوی، گلستان و مازندران به ترتیب برابر با ٢٢/١5، ٦٦/١4 و ۸٢/١٧...
متن کاملResistance of Thrips tabaci to pyrethroid and organophosphorus insecticides in Ontario, Canada.
Onion thrips, Thrips tabaci Lindeman, were collected from commercial onion fields in 2001, 2002 and 2003 to assess resistance to lambda-cyhalothrin, deltamethrin and diazinon. In 2001, six of eight adult populations were resistant to lambda-cyhalothrin, with resistance ratios (RR) ranging from 2 to 13.1 and four of these were also resistant to deltamethrin, with RR ranging from 19.3 to 120. Thr...
متن کاملImpact of Insecticides on Parasitoids of the Leafminer, Liriomyza trifolii, in Pepper in South Texas
Liriomyza leafminers (Diptera: Agromyzidae) are cosmopolitan, polyphagous pests of horticultural plants and many are resistant to insecticides. Producers in South Texas rely on insecticides as the primary management tool for leafminers, and several compounds are available. The objective of this study is to address the efficacy of these compounds for controlling Liriomyza while minimizing their ...
