Neonicotinoids are a popular and widely-used class of insecticides whose heavy usage rates purported negative impacts on bees other beneficial insects has led to questions about their mobility accumulation in the environment. Neonicotinoid compounds currently registered for over 140 different crop uses United States, with commercial growers continuing rely heavily neonicotinoid control key insect pests through combination in-ground foliar applications. In 2008, Wisconsin Department...
During the past 30 years, at least seven species of injurious insects are known to have evolved strains that more difficult kill with recognised chemical insecticides than normal populations these pests. In 1939 it was reported from East London area farmers were experiencing difficulty in controlling one host blue tick, B. decoloratus , by regular dipping 7-day strength arsenical wash. Field observations confirmed this. A technique for treating ticks laboratory is discussed detail. This has...
Wheat stem sawfly (WSS), Cephus cinctus (Hymenoptera: Cephidae), is a native grass-feeding insect and one of the most important pests wheat in North America. Yield losses from WSS can be due to boring and/or cutting which causes plants lodge. Current methods, such as solid varieties insecticides, do not effectively control WSS. A better understanding emergence, population size, related environmental factors critical building efficient effective integrated pest management (IPM) strategies for...
Abstract Diversifying agricultural systems by growing more than one crop species in an area can decrease pest and disease pressure increase yields. However, there is a lack of information on how diversity at larger spatial scales influences pressure. Here, we investigated landscape‐scale affects aphid vector communities prevalence non‐persistently transmitted potato virus Y (PVY). To test the influence PVY communities, conducted field study during 2020 2021 seasons San Luis Valley, Colorado,...
Abstract The Colorado potato beetle ( Leptinotarsa decemlineata ) is a major agricultural pest of solanaceous crops. An effective management strategy employed by producers to control this species the use systemic insecticides. Recent emphasis has been placed on neonicotinoid Despite efforts curb resistance development through integrated approaches, neonicotinoids in L. populations continues increase. One contributing factor may be alterations insect fatty acids, which have multiple metabolic...
Aster Yellows phytoplasma (AYp; ‘ Candidatus Phytoplasma asteris’) is an obligate bacterial pathogen that the causative agent of multiple diseases in herbaceous plants. While this has been examined depth for its disease characteristics, knowledge about spatial and temporal dynamics spread lacking. The found plant’s phloem vectored by leafhoppers (Cicadellidae: Hemiptera), including aster leafhopper, Macrosteles quadrilineatus Forbes. leafhopper a migratory insect pest overwinters southern...
Spotted-wing drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), is an invasive economic pest of soft-skinned and stone fruit across the globe. Our study establishes both a predictive generalized linear mixed model (GLMM), additive (GAMM) dynamic seasonal phenology D. based on four years adult monitoring trap data in Wisconsin tart cherry orchards collected throughout growing season. The models incorporate year, field site, relative humidity, degree days (DD); relate these...
The rapid spread of the single host arsenic-resistant blue tick, B. decoloratus , a transmitter piroplasmosis and anaplasmosis, seriously affected large important cattle ranching area in South Africa. Biological tests, using laboratory technique described an earlier paper, enabled most effective “Gammexane” preparations to be rapidly selected from numbers experimental dips. was also employed as supplement chemical analyses dip wash samples where only total hexachlorocyclohexane not gamma...
Tetranychus urticae (Koch) is an economically important pest of many agricultural commodities world-wide. Multiple acaricides, including bifenazate, bifenthrin, and extoxazole, are currently registered to control T . However, populations in different growing regions have developed acaricide resistance through multiple mechanisms. Within , single nucleotide polymorphisms (SNPs) been documented genes which associated with phenotypes. The detection these mutations TaqMan qPCR has suggested as a...
The root system of 350 loblolly pine trees in 14 plots were excavated utilizing a bulldozer and evaluated according to the annosus rot (Heterobasidion annosus) symptom expression roots, i. e. resin soaked stringy. annual increments healthy (<1% colonized) diseased groups compared for each last five years growth. There was significant growth difference between these at about 4% per year or 19% total.
Fourteen plots of 25 loblolly pines each were excavated by bulldozers in order to determine incidence and severity Heterobasidion annosus asymptomatic pine Virginia. Of the 350 trees sampled, 85% infected with H. annosus. Basidiocarps found on 9% sampled trees. The average frequency roots per tree annosus, for all measured (trees > 1% infection evident), was 30% primary 31% secondary roots. root length 14% 15%
Aster Yellows phytoplasma (AYp; Candidatus Phytoplasma asteris) is associated with diseases of herbaceous plants, including ornamentals and important commercial vegetable grain crops. The aster leafhopper (ALH; Macrosteles quadrilineatus Forbes) the predominant vector these bacteria, though other species can acquire transmit AYp. Potentially inoculative leafhoppers are reported to overwinter in southern United States migrate northern latitudes spring. Examining genetic similarities...
BACKGROUND The purse-string suture (PSS) is a simple, reversible method for reconstructing skin cancer defects. Its utility may be underappreciated in head and neck reconstructive surgery. OBJECTIVE To evaluate the of PSS as an adjunct to ladder when MATERIALS AND METHODS This prospective nonrandomized cohort included 109 consecutive adult patients with defects resulting from resection. was placed every patient after Patients were evaluated before placement, final methods recorded.
