| efficacy of a long-lasting bifenthrin-treated net against horticultural pests and its compatibility with the predatory mite amblyseius swirskii and the parasitic wasp eretmocerus mundus. | insecticide-treated nets (itns) have been investigated recently for their use in agriculture. depending on the insecticide, the hole size and the way they are produced, these nets can target different pests and therefore they could be interesting options for use in integrated pest management (ipm). as the information on their compatibility with beneficial fauna is practically negligible, in this work we have tested the compatibility of an experimental bifenthrin long-lasting insecticide-treated ... | 2017 | 28066972 |
| constitutive and operational variation of learning in foraging predatory mites. | learning is widely documented across animal taxa but studies stringently scrutinizing the causes of constitutive or operational variation of learning among populations and individuals are scarce. the ability to learn is genetically determined and subject to constitutive variation while the performance in learning depends on the immediate circumstances and is subject to operational variation. we assessed variation in learning ability and performance of plant-inhabiting predatory mites, amblyseius ... | 2016 | 27814380 |
| prey and pollen food choice depends on previous diet in an omnivorous predatory mite. | the time allocated by omnivorous predators to consuming prey versus plant-provided foods (e.g., pollen) directly influences their efficacy as biocontrol agents of agricultural pests. nonetheless, diet shifting between these two very different food sources remains poorly understood. we hypothesized that previous diet composition influences subsequent choice of prey and plant food types. we tested this hypothesis by observing the foraging choices of amblyseius swirskii (athias-henriot) mites (meso ... | 2016 | 27271945 |
| benefit-cost trade-offs of early learning in foraging predatory mites amblyseius swirskii. | learning is changed behavior following experience, and ubiquitous in animals including plant-inhabiting predatory mites (phytoseiidae). learning has many benefits but also incurs costs, which are only poorly understood. here, we addressed learning, especially its costs, in the generalist predatory mite amblyseius swirskii, a biocontrol agent of several herbivores, which can also survive on pollen. the goals of our research were (1) to scrutinize if a. swirskii is able to learn during early life ... | 2016 | 27006149 |
| acute toxicity and sublethal effects of fenpyroximate to amblyseius swirskii (acari: phytoseiidae). | knowledge about the effects of pesticides on biological control agents is required in order to successfully implement integrated pest management programs. the predatory mite amblyseius swirskii athias-henriot has been used to control thrips, whiteflies, and broad mites in vegetable production; however, effects of fenpyroximate, an acaricide and insecticide used in vegetable crops, on a. swirskii have not been evaluated. the effect of four residual concentrations of fenpyroximate on a. swirskii f ... | 2015 | 26470228 |

| early establishment of the phytoseiid mite amblyseius swirskii (acari: phytoseiidae) on pepper seedlings in a predator-in-first approach. | the establishment of biocontrol agents is critical for success of biological control strategies. predator-in-first (pif) is a prophylactic control strategy that aims to establish predators before the appearance of pests in an agro-ecosystem. pif uses the ability of generalist phytoseiid mites to survive, develop and reproduce on pollen and thus establish in the absence of prey. the early establishment of populations of natural enemies helps control the pests at their incipient stage of infestati ... | 2015 | 25772442 |
| amblyseius swirskii in greenhouse production systems: a floricultural perspective. | the predatory mite amblyseius swirskii athias-henriot is a biological control agent that has the potential to play an important role in pest management in many greenhouse crops. most research on this predatory mite has focused on its use and efficacy in greenhouse vegetables. however, an increasing number of growers of greenhouse ornamental crops also want to adopt biological control as their primary pest management strategy and find that biological control programs developed for vegetables are ... | 2015 | 25501276 |
| plant-feeding and non-plant feeding phytoseiids: differences in behavior and cheliceral morphology. | in previous studies plant feeding behavior of plant- and non-plant feeding phytoseiids was never examined directly. moreover, in these studies the cheliceral morphology of phytoseiids was not associated with their ability to feed on plants. in the present study, we monitored the plant-feeding behavior of euseius scutalis and amblyseius swirskii. only e. scutalis was observed penetrating the leaf surface with the movable digit and feeding. second, using a dye and coloring the gut as an indicator ... | 2012 | 22729501 |
