fitness costs associated with low-level dimethoate resistance in phytoseiulus macropilis.phytoseiulus macropilis banks (acari: phytoseiidae) is an effective predator of tetranychid mites, but there are no data on its response to pesticides. we investigated the resistance of the predatory mite p. macropilis to the acaricides abamectin and dimethoate, and we examined the fitness costs associated with resistance. two populations were tested: one from conventional cultivation and another from an area not commercially exploited. after the application of acaricides to the predator, we det ...201323435931
comparison of thermal activity thresholds of the spider mite predators phytoseiulus macropilis and phytoseiulus persimilis (acari: phytoseiidae).the lower and upper thermal activity thresholds of the predatory mite phytoseiulus macropilis banks (acari: phytoseiidae) were compared with those of its prey tetranychus urticae koch (acari: tetranychidae) and one of the alternative commercially available control agents for t. urticae, phytoseiulus persimilis athias-henriot. adult female p. macropilis retained ambulatory function (ctmin) and movement of appendages (chill coma) at significantly lower temperatures (8.2 and 0.4 °c, respectively) t ...201323011107
phytoseiidae (acari: mesostigmata) within citrus orchards in florida: species distribution, relative and seasonal abundance within trees, associated vines and ground cover citrus orchards on reduced- to no-pesticide spray programs were sampled for predacious mites in the family phytoseiidae (acari: mesostigmata) in central and south central florida. inner and outer canopy leaves, open flowers, fruit, twigs, and trunk scrapings were sampled monthly between september 1994 and january 1996. vines and ground cover plants were sampled monthly between september 1994 and january 1996 in five of these orchards. the two remaining orchards were on full herbicide progr ...201121499778
herbivore population suppression by an intermediate predator, phytoseiulus macropilis, is insensitive to the presence of an intraguild predator: an advantage of small body size?recent work in terrestrial communities has highlighted a new question: what makes a predator act as a consumer of herbivores versus acting as a consumer of other predators? here we test three predictions from a model (rosenheim and corbett in ecology 84:2538-2548) that links predator foraging behavior with predator ecology: (1) widely foraging predators have the potential to suppress populations of sedentary herbivores; (2) sit and wait predators are unlikely to suppress populations of sedentary ...200415278424
reproductive parameters of phytoseiulus macropilis (banks) fed with tetranychus urticae koch (acari: phytoseiidae, tetranychidae) in laboratory.predatory mites that belong to the phytoseiidae family are one of the main natural enemies of phytophagous mites, thus allowing for their use as a biological control. phytoseiulus macropilis (banks, 1904) (acari: phytoseiidae) is among the main species of predatory mites used for this purpose. tetranychus urticae koch, 1836 (acari: tetranychidae) is considered to be one of the most important species of mite pests and has been described as attacking over 1,100 species of plants in 140 families wi ...201627409230
antipredator behaviours of a spider mite in response to cues of dangerous and harmless predators.prey are known to invest in costly antipredator behaviour when perceiving cues of dangerous, but not of relatively harmless predators. whereas most studies investigate one type of antipredator behaviour, we studied several types (changes in oviposition, in escape and avoidance behaviour) in the spider mite tetranychus evansi in response to cues from two predatory mites. the predator phytoseiulus longipes is considered a dangerous predator for t. evansi, whereas phytoseiulus macropilis has a low ...201627067101
morphological and molecular diagnostics of phytoseiulus persimilis and phytoseiulus macropilis (acari: phytoseiidae).this study focuses on the diagnostics of two natural enemy species, belonging to the genus phytoseiulus in the family phytoseiidae (sub-family amblyseiinae): p. macropilis and p. persimilis. these two species are of primary importance in biological control all over the world. however, they are morphologically very similar and specific diagnostics is difficult. this study utilizes mitochondrial molecular markers (12s rrna and cytb mtdna) to differentiate these two species. morphological analyses ...201020473708
jerking in predaceous mites (acari: phytoseiidae) with emphasis on larvae.jerking, a behavior involving a pronounced and often repeated lunging of the body, was studied in larvae among seven species of phytoseiid mites, euseius finlandicus, galendromus occidentalis, neoseiulus californicus, neoseulus fallacis, phytoseiulus macropilis, phytoseiulus persimilis and typhlodromus pyri, and in the nymphal stages of n. fallacis. this behavior was observed in larvae of six of the seven species and in all active immature stages of n. fallacis. jerking was usually triggered by ...200111697785
[compared biology and behavior of tetranychus urticae koch (acari: tetranychidae) and phytoseiulus macropilis (banks) (acari: phytoseiidae) on bollgard and non-transgenic isoline cotton].the two spotted spider mite, tetranychus urticae koch, is a nontarget herbivore of bt-cotton, but acquires and accumulates higher levels of cry toxin than that expressed by transgenic plants. this work investigated the development and reproduction of t. urticae and of the predator phytoseiulus macropilis banks, during three successive generations looking for potential nontarget effect. in addition, behavioral studies on feeding preference, oviposition, and predation were carried out on bt and no ...201020676505
evaluation of the predatory mite phytoseiulus macropilis (acari: phytoseiidae) as a biological control agent of the two-spotted spider mite on strawberry plants under greenhouse conditions.the predatory mite phytoseiulus macropilis is a potential biological control agent of the two-spotted spider mite (tssm) tetranychus urticae on strawberry plants. its ability to control tssm was recently assessed under laboratory conditions, but its ability to locate and control tssm under greenhouse conditions has not been tested so far. we evaluated whether p. macropilis is able to control tssm on strawberry plants and to locate strawberry plants infested with tssm under greenhouse conditions. ...200919016335
susceptibility to deltamethrin in the predatory mites neoseiulus californicus and phytoseiulus macropilis (acari: phytoseiidae) populations in protected ornamental crops in brazil.knowledge of inter and intra-specific variation in the susceptibility of natural enemies to pesticides could help to better design integrated pest management strategies. the objective of this research was to evaluate the susceptibility to deltamethrin in populations of the predatory mites neoseiulus californicus (mcgregor) and phytoseiulus macropilis (banks) populations collected from protected ornamental crops in brazil. the susceptibility to deltamethrin was characterized against immature and ...201222718193
pyrethroid resistance in phytoseiulus macropilis (acari: phytoseiidae): cross-resistance, stability and effect of synergists.phytoseiulus macropilis banks (acari: phytoseiidae) is an effective predator of tetranychus urticae koch (acari: tetranychidae). the objectives of this research were to study the stability of fenpropathrin resistance and the cross-resistance relationships with different pyrethroids, and also to evaluate the effect of synergists [piperonyl butoxide (pbo), diethyl maleate (dem) and s,s,s-tributyl phosphorotrithioate (def)] on fenpropathrin resistant and susceptible strains of this predaceous mite. ...201626530989
biological control of tetranychus urticae by phytoseiulus macropilis and macrolophus pygmaeus in tomato greenhouses.biological control against phytophagous arthropods has been widely used under greenhouse conditions. its success is dependent on a number of factors related to the abiotic conditions and to the interactions between pests and biological control agents. in particular, when multiple predator species are introduced to suppress one pest, competitive interactions might occur, including intraguild predation (igp). in tomato crops, the spider mite tetranychus urticae koch is a very problematic phytophag ...201626481345
two-spotted spider mite and its natural enemies on strawberry grown as protected and unprotected crops in norway and brazil.cultivation of strawberry in plastic tunnels has increased considerably in norway and in southeastern brazil, mainly in an attempt to protect the crop from unsuitable climatic factors and some diseases as well as to allow growers to expand the traditional production season. it has been hypothesized that cultivation under tunnels could increase the incidence of one of its major pests in many countries where strawberry is cultivated, including norway and brazil, the two spotted spider mite, tetran ...201525948508
