This article documents the addition of 299 microsatellite marker loci and nine pairs of single-nucleotide polymorphism (SNP) EPIC primers to the Molecular Ecology Resources (MER) Database. Loci were developed for the following species: Alosa pseudoharengus, Alosa aestivalis, Aphis spiraecola, Argopecten purpuratus, Coreoleuciscus splendidus, Garra gotyla, Hippodamia convergens, Linnaea borealis...
The first detections of Asian citrus psyllid, Diaphorina citri Kuwayama, in North America occurred almost simultaneously in Florida and in the Caribbean (Guadeloupe). Damaging populations on citrus have been reported in Florida but not in Puerto Rico where the psyllid was first detected in 2001, having probably arrived with its parasitoid, Tamarixia radiata Waterston. In an effort to identify a...
Biorational foliar sprays and a novel application method of soaking transplants in imidacloprid were evaluated for control of adult and larval cottonwood leaf beetle, Chrysomela scripta F., on hybrid poplar, with emphasis on conservation of coccinellid predators. Foliar sprays of four biorational insecticides killed adult and larval C. scripta: Bacillus thuringiensis (B.t.) variety tenebrionis ...
We compare the efficiencies of different stages of Hippodamia variegata (Coleoptera: Coccinellidae) preying on Aphis fabae (Scolpoli) (Hemiptera: Aphididae) by estimating the functional responses of all stages. The experiments were carried out on leaf disks in petri dishes with 15-20 replicates. Our results revealed that all larval instars and adult males and females of H. variegata exhibited t...
Insects in Kentucky bluegrass seed production fields in Oregon, Idaho, and Washington were sampled just before harvest and their association with ergot conidia of Claviceps purpurea Fr. (Tul.) was evaluated during 1996-1998. A diversity of insects was observed at all three locations. The most abundant beneficial insects collected with sweep nets were Nysium spp., Nabis spp., ichneumonid wasps, ...
We studied life history responses of larvae of three coccinellid species, Coleomegilla maculata (DeGeer), Hippodamia convergens Guerin-Meneville, and Harmonia axyridis (Pallas), when deprived of food for different periods of time during the fourth stadium. The coccinellid species did not differ in starvation resistance when larvae were starved throughout the stadium; however, for larvae fed onl...
Mitogenome sequences are highly desired because they are used in several biological disciplines. Their elucidation has been facilitated through the development of massive parallel sequencing, accelerating their deposition in public databases. However, sequencing, assembly and annotation methods might induce variability in their quality, raising concerns about the accuracy of the sequences that ...
گرچه در اغلب موارد گیاه خواران با انواع مختلفی از شکارگرها مواجه اند، اما بسیاری از مطالعات آزمایشگاهی به اثرات شکارگری فردی تاکید کرده اند. اثرات انواع مختلف شکارگرها ممکن است به شکل پیچیده ای بر جمعیت طعمه تاثیر گذارد. برای درک اثر کاربرد مضاعف شکارگرها بر نرخ مصرف آنها، به ارزیابی برهم کنش شکارگری درون رسته ای بین لارو سن سوم مگس شکارگر episyrphus balteatus de geer و لاروهای سنین دوم ...
کفشدوزکhippodamia variegata گونه ای با پراکنش وسیع در ایران است. در این تحقیق ویژگی های زیستی این کفشدوزک با تغذیه از شته سبز گندم sitobion avenae، شته روسی گندم diuraphis noxia و شته سمی گندم schizaphis graminum در اتاقک رشد با دمای 1±25 درجه سلسیوس، رطوبت نسبی 5±65 درصد و دوره ی نوری 16 ساعت روشنایی و 8 ساعت تاریکی مورد بررسی قرار گرفت. به منظور انجام آزمایش، از تخم¬های هم¬سن کفشدوزک استفاده ...
