AbstractDuring 2005–2007, 1,332 individuals of predatory mites were found in integrated and ecological orchards in Slovakia. Seven predatory mite species of the family Phytoseiidae, namely Phytoseius echinus, Phytoseiulus macropilis, Euseius finlandicus, Typhlodromus pyri, Paraseiulus triporus, Amblyseius andersoni and Neoseiulella tiliarum, were identified. Out of 1,332 individuals, 519 (39.0%) were found in the apple orchards and 813 (61.0%) in the pear orchards. Out of all predatory mite individuals, 460 (34.5%) were found in the integrated pest management system (IPM) and 872 (65.5%) in the ecological pest management system (EPM). In apple orchards, P. echinus was dominant and constituted 49.3% of the detected mites. In pear orchards, E. finlandicus was dominant and constituted 48.7% of the detected mites. Typhlodromus pyri was also abundant, especially in pear orchards. The other species were less abundant.

Abstract The entomopathogenic fungus “Metarhizium anisopliaeˮ and predatory mite “Phytoseiulus macropilisˮ are effective biological controlling agents of Tetranychus urticae. Recent studies have shown that predatory mites, used as biocontrol agents can be loaded with entomopathogenic fungal conidia to increase infection rates in pest populations. It was necessary to study the effect of M. anisopliae against P. macropilis before executing the experiment. The results showed that the predator mite was more effected by 1×109 conidia/ml of M. anisopliae, while the predator had low effect with 1×106 conidia/ml of M. anisopliae. It was found that the predator had poor effect at indirect spray. Results showed that dispersal of M. anisopliae loaded on P. macropilis delivered high numbers of conidia to T. urticae infested leaves, thereby increased the proportion of T. urticae that came into contact with the fungus.Our study suggests that loading certain predatory mite species with fungal conidia can increase their capacity to suppress thrips populations by combining predation and dispersing pathogens when releasing the loading predatory mite with M. anisopliae for controlling T. urticae on cucumber crop under greenhouse conditions

Potential Biocontrol Agent

Spiny snout mite (Neomolgus capillatus) is a potential biocontrol agent for clover flea (Sminthurus viridis) a white clover pest on dairy farms in warmer and wetter parts of New Zealand In the 1990s this mite was introduced from Brittany France into Tasmania for clover flea control Results during the release programme were highly promising and subsequent anecdotal farmer reports indicate widespread decreases in damage As N capillatus is a predatory mite and already known to attack nontarget organisms habitat specificity will determine whether it could be introduced into New Zealand without risk to native insects To assess this pastures on nine of the original Tasmanian release farms and adjacent nontarget habitats ranging from bush wetlands eucalypt stands to sand dune country were sampled in April 2014 Litter samples were collected heat extracted and mite species identified Neomolgus capillatus was found at effective densities in pastures that had good clover cover Where present it displaced Bdellodes spp mites that are ineffective against clover flea No N capillatus were found in the nontarget habitats all of which lacked clover and contained other predatory mites including Bdellodes spp Therefore the preference by N capillatus for lush pastures makes it an excellent prospect for introduction as a biocontrol agent into clover flea prone regions of New Zealand

Abstract 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 with economic value. The objective of the present study was to investigate, in the laboratory, the reproductive parameters of the predatory mite P. macropilis when fed T. urticae. Experiments were conducted under laboratory conditions at 25 ± 2 °C of temperature, 70 ± 10% RH and 14 hours of photophase. In addition, biological aspects were evaluated and a fertility life table was established. The results of these experiments demonstrated that the longevity of adult female was 27.5 days and adult male was 29.0 days. The population was estimated to increase approximately 27 times (Ro) in mean generation time (T), which was 17.7 days. Lastly, the mite population grew 1.2 times/day (λ) and doubled every 3.7 days (TD).

It is now clear that over use of pesticides and intensive management of orchards can lead to drastic declines in apple pollinator abundance and crop failures. During the period of study a grower’s survey was conducted to know about knowledge of farmers on native insect pollinators, pollinator management practices, their perceptions of the importance and utility of native pollinators, and their attitudes regarding pesticide application. Despite of having significant knowledge of managed pollination, only few farmers (2%) adopted supplementary methods of pollination (renting honey bee colonies, hand pollination etc.). In Pulwama, 60% of farmers had knowledge about native insect pollinators and 40% did not have any idea of native pollinators and in case of Shopian, the figures were fifty-fifty i.e. 50% had knowledge about native insect pollinators and 50% were unaware. During the period of investigation, native insect pollinators were sampled from different apple orchards under different management systems in early spring during apple flowering. A total of 17 species of insect pollinators belonging to 11 families and 3 orders_ Hymenoptera, Diptera and Lepidoptera registered their occurrence at all the studied apple orchards of the Kashmir Valley. At all the study sites i.e. apple orchards under different management systems, family Halictidae and Empididae registered their presence as dominant groups. The % family contribution of the former at different orchard types decreased with increase in the intensity of the management system and the % family contribution of the later however, showed a direct relationship with the management system found, i.e. the more intense the system, the more abundant was the group. Other groups in general did not show any greater differences in abundances at different sites studied.

Eighteen predatory mite species of the family Phytoseiidae are reported from three sites of the Cerrado ecosystem in the State of S o Paulo, southeastern Brazil, on seven plant species of the family Myrtaceae. This paper provides a list of those species and compares relevant morphological characteristics of the specimens collected with those of the original descriptions and/ or redescriptions of the corresponding species. A key is provided to help in the separation of the species mentioned in the paper. Some of the species collected have been reported as common predators on dominant crops in the region where the work was done. Their occurrence on Myrtaceae plants found naturally in the Cerrado ecosystem indicates that those plants could represent important reservoirs of those predators.

The Family

The biology and systematics of the predatory mites of the family Laelaptidae have received increased attention since they have been shown to be of importance in the control of phytophagous mites, especially Tetranychidae, resistant to modern insecticides. The predatory mites of economic importance are almost entirely confined to the sub–family Phytoseiinae Berl., 1910.

Abstract A test was conducted in Cheshire, CT, to determine the efficacy of five miticides and two predatory mite species for control of TSSM. There was also an untreated check. Treatments were arranged in a RCBD with four replications. Plots consisted of 12 container-grown plants in a 1.7 ft2 plastic flat. The trial cultivar ‘Variegate’ was planted on 1 Apr. Miticides were applied to the foliage from the top and sides with a Solo backpack sprayer at 60 psi with 35.3 gpa. Predatory mites were placed into the treatment plots by gently brushing them off of the lip of the shipment container. All treatments were applied on 18 Jul. Five leaves were removed from each treatment plot on 17, 25 Jul and 1, 8 and 15 Aug to count the eggs and motile TSSM. Data were analyzed by ANOVA and LSD.
