... ObjectivesTyrophagus putrescentiae (Schrank; Sarcoptiformes: Acaridae), the most common arthropod pest of dry-cured ham, is controlled in the U.S. dry cured ham industry with methyl bromide (MB) fumigation. However, MB fumigation will be phased out of use since it is an ozone depleting substance. The objective of this research was to evaluate ham nets that were infused with food-grade ingredients ...

Abstract:
... Potato varieties may respond differently to the occurrence of arthropod pests including plant-pathogen. Although the potato psyllid, Bactericera cockerelli Sulc. (Hemiptera:Triozidae), the putative vector of Zebra Chip (ZC) disease, has been historically reported in the southern, central and western United States, the occurrence of the disease in the Pacific Northwest (PNW) is relatively new. Thus ...
... Three curculionid species Apion pisi F., Hypera variabilis Herbst and Sitona lineatus L. and an eriophyid mite, Eriophyes medicaginis K. were studied in a three years lucerce plantation for the period April 1986 to March 1987. A. pisi and H. variabilis were found to be absent from the field for a quite long period, lasting from July to October for the former and from end of June to mid November fo ...
... Investigations were undertaken to clarify the biology of green lacewing Mallada boninensis on its hosts Helopeltis theivora and Oligonychus coffeae, which are two major arthropod pests of tea crop and on an artificial diet. No significant variations were recorded in terms of preoviposition period, oviposition period, oviposition rate, total eggs, hatching success, larval survival and adult emergen ...
... Biorational insecticides are being increasingly emphasized for inclusion in integrated pest management programs for invasive insects. The entomopathogenic fungus, Isaria fumosorosea, can be used to help manage the Asian citrus psyllid with minimal impact on beneficial arthropods, but its effectiveness may be compromised by agrochemicals used to control concurrent arthropod pests and diseases. We e ...
... Coccinella septempunctata is a common insect predator that provides biological control of many destructive arthropod pests. An assessment of the toxicity of pesticides to predators is a necessary component of Integrated Pest Management (IPM) strategies. In order to evaluate the risks of field insecticide application, we studied the influence of chlorantraniliprole on C. septempunctata larvae using ...
... Sugarcane is an important industrial crop in Iran, and this crop is vulnerable to attack by several arthropod pest species. Sugarcane whitefly Neomaskellia andropogonis (Corbett) (Homoptera: Aleyrodidae) is a relatively new emerging pest which affect sugarcane fields in late summer. Field trials were carried out during early September until late November 2015 at Salman Farsi Agro-Industry, Ahwaz, ...

Abstract:
... The release of biocontrol agents for the management of arthropod pests on greenhouse tomatoes is an increasingly widespread technique in Europe. The predatory mirid Macrolophus pygmaeus was initially used for control of the greenhouse whitefly, Trialeurodes vaporariorum, but its range of application expanded when it was found to have the potential for management of the tomato leafminer, Tuta absol ...

Abstract:
... BACKGROUND: Biological control of phytophagous mites in orchards requires that pesticides used to manage other arthropod pests or diseases are harmless to predacious mites, as these are essential to keep phytophagous mites at non-injurious population levels. This study evaluates the possible toxic attributes of acetamiprid, imidacloprid, thiacloprid, thiamethoxam, spirodiclofen, spinosad and metho ...
... BACKGROUND: Nearly all corn seed in the US is coated with neonicotinoid insecticides to protect against soil and foliar arthropod pests. Exposure in the soil and the systemic activity in the plant can pose non‐target risks. We assessed the community‐level effects of clothianidin‐treated seed on the diversity and abundance of arthropod communities in a no‐till corn agroecosystem over a single growi ...
... BACKGROUND: Neoseiulus fallacis (Garman) is a key predator of tetranychid mites in integrated pest management (IPM) programs across Canada. This study identified compounds that would be recommended for tier-II field evaluations in an IPM program.RESULTS: The overall egg mortality caused by the six insecticides was negligible as it extended from 0 to 12.1%. Imidacloprid was classified as toxic to a ...
... Research here explored the use of controlled atmospheres (CA) for managing arthropod pests that infest dry-cured hams. Experiments were conducted with low oxygen (O2) achieved with low pressure under a vacuum, high carbon dioxide (CO2), and ozone (O3). Results showed that both low O2 and high CO2 levels required exposures up to 144 h to kill 1 ...

Abstract:
... The cheyletid predator Hemicheyletia wellsina was found in association with orchid pests in a Florida greenhouse. The life history of H. wellsina was determined using the two-spotted spider mite, Tetranychus urticae, as prey in the laboratory. Hemicheyletia wellsina is arrhenotokous, with mated females producing a female-biased sex ratio of 3.4:1. Adult longevity averaged 30.2 days, with females p ...
... Plants possess anti‐herbivore defences that could be exploited for crop protection. The potential for deploying physical defence traits for more sustainable pest management (i.e. reduced pesticide application) has not been fully realised. Using a perennial crop (red raspberry, Rubus idaeus), we take the novel approach of quantifying within‐ and between‐genotype variation in a resistance trait, lea ...
... 1 Landscape management for enhanced natural pest control requires knowledge of the ecological function of the habitats present in the landscape mosaic. However, little is known about which habitat types in agricultural landscapes function as reproduction habitats for arthropod pests and predators during different times of the year. 2 We studied the arthropod assemblage on six crops and on the seve ...
... Much is known about the physiology of tick salivation, but nothing is known about the movement of water through the cell membranes of salivary glands, a phenomenon usually associated with water channels or aquaporins (AQPs). An AQP, RsAQP1, was identified in a salivary gland cDNA library of Rhipicephalus sanguineus. In the first functional characterization of an acarine AQP, Xenopus oocytes expres ...

Abstract:
... Conservation of natural enemies is an important approach for enhancing biological control. Selective insecticides have become important for managing arthropod pests, and the prospects for their use in combination with biological control agents are increasing. In addition, progress has been made in recent decades to develop reduced-risk insecticides that have novel modes of action and, therefore, l ...

... Insect parasitoids are often manipulated to improve biological control programs for various arthropod pests. Volatile compounds can be a relevant cue used by most parasitoid hymenoptera for host or host microhabitat location. Here, we studied olfactory responses of the braconid Asobara japonica Belokobylskij, an Asiatic endoparasitoid of the invasive pest Drosophila suzukii (Matsumura), toward its ...
... Entomopathogenic microbes such as Spodoptera litura nucleopolyhedrovirus (SpltNPV), Metarhizium anisopliae, and Pseudomonas fluorescens are biological agents used for the control of multiple arthropod pests. The objective of this study was to assess their effects on the biological parameters of Spodoptera litura (Lepidoptera: Noctuidae) larvae, and its natural reduviid predator Rhynocoris kumarii ...
... Selective insecticide application is one important strategy for more precisely targeting harmful insects while avoiding or mitigating collateral damage to beneficial insects like honey bees. Recently, macrocyclic lactone-class insecticides have been introduced into the market place as selective bio-insecticides for controlling many arthropod pests, but how to target this selectivity only to harmfu ...
