Behavioral characteristics such as aggressiveness and predation preference of the phytoseiid predatory species, Amblyseius swirskii, Neoseiulus californicus and Phytoseiulus persimilis (Acari: Phytoseiidae) were investigated when applied together. We quantified the chance and time of a successful attack to a heterospecific larva as aggressiveness of adult females. In order to the determine the predation preference of adult females equal combination of con/heterospecific larvae were presented to as prey in absence of their main prey (Tetranychus urticae Koch) for 24 h. Experiments were carried out in growth chamber at 25±1 ºC, 65±5% RH and 16:8 (L: D) hour photoperiod regimens. The results showed that adult females of N. californicus needed 39.65±7.46 min. to attack and kill the larva of P. persimilis which was remarkably less than that recorded (227.80±28.38 min.) for adult females of P. persimilis to attack and kill N. californicus larva. N. californicus was estimated more aggressive than P. persimilis. The mean estimated attack time of A. swirskii and P. persimilis was estimated 18.55±2.89 and 201.70±25.42 min., respectively. A. swirskii was considered more aggressive than P. persimilis against heterospecific larvae. The predation preference index (Manly´s β) were indicated that N. californicus was able to recognize con/heterospecific larva, resulted more preference for heterospecific larvae (P. persimilis) in absence of T. urticae, while adult P. persimilis showed no preference (between con and heterospecific larva). Manly´s β, for A. swirskii was 0.706 and 0.294, for P. persimilis 0.369 and 0.630 on hetero and conspecific larvae, respectively. Results of this study showed that, A. swirskii and N. californicus are general predators were able to roecgnize con/heterospecific larva and preferred to feed on heterospecific larvae and get benefit from intraguild predation.

Abstract Background The predatory mites, Neoseiulus californicus (McGregor), N. barkeri (Hughes), and Amblyseius swirskii Athias-Henriot, are important predators attacking many insect and mite pests. They can coexist in the same habitat and engage in intraguild predation (IGP). Main body IGP was assessed among the exotic one N. californicus and the native species N. barkeri and A. swirskii as Intraguild predator (IG-predator)/intraguild prey (IG-prey) in either absence or presence of extra-guild prey Tetranychus urticae Koch (EG-prey). In the laboratory, the physiological parameters, longevity, fecundity, and predation rate of these predatory mites’ females, fed on EG-prey, were evaluated, where phytoseiid larvae are considered as (IG-prey) or combined IG-prey with EG-prey. All predatory species consumed larval stages of each other’s, but in case of N. californicus, females failed to sustain oviposition on N. barkeri larvae. Also, it was noticed that N. californicus females killed 3 times more A. swirskii larvae than N. barkeri larvae, whereas A. swirskii consumed more N. californicus than N. barkeri larvae, respectively. Neoseiulus californicus lived longer on T. urticae and A. swirskii larvae than on N. barkeri, while the latter survived longer on T. urticae only than on the other prey or with combinations with T. urticae. Amblyseius swirskii lived shorter when fed exclusively on T. urticae or IG-prey than on EG-prey combined with IG-prey. In choice experiments, N. californicus showed a higher preference to consume more T. urticae than any of phytoseiid larvae. The comparison between T. urticae and IG-prey diets definite the higher influence of T. urticae on the fecundity in N. californicus and N. barkeri than on IG-prey, whereas in A. swirskii fecundity was as equal on T. urticae as on IG-prey N. californicus larvae. Conclusion A. swirskii seemed to be the strongest IG-predator.

Predatory mites such as Neoseiulus californicus McGregor (Fig. 1) and Phytoseiulus persimilis Athias-Henriot (Fig. 2) feed on important fruits and ornamental pests such as the twospotted spider mite (Tetranychus urticae Koch), broad mite (Polyphagotarsonemus (Stenotarsonemus) latus Banks), cyclamen mite (Tarsonemus pallidus L.), and other mite species. These predatory mites are associated with several agricultural cropping systems including strawberries, raspberries, roses, grapes, citrus, ornamentals, and vegetables. Predatory mites have been used as an alternative to miticides on a variety of crops. Their commercial availability is crucial. This document is HS1000, one of a series of the Horticultural Sciences Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

The predatory mite Neoseiulus californicus (McGregor) has characteristics of both type II specialist predatory mites and type III generalist predatory mites. N. californicus prefers Tetranychid mites as food, but will also consume other mite species, small insects, such as thrips, and even pollen when the primary prey is unavailable. N. californicus is often used to control the twospotted spider mite, Tetranychus urticae Koch, and other phytophagous mites on various crops in temperate and subtropical regions around the world.  This document is EENY-359, one of a series of the Entomology and Nematology Department, UF/IFAS Extension.
