“…Recently, several growers have reported control failures against thrips, and resistance by F occidentalis has been reported to four major classes of insecticides: organochlorines, organophosphates, carbamates and pyrethroids 6–9. Three factors may contribute to the development of resistance in F occidentalis : short generation time, high fecundity6 and haploid males in which resistance genes are directly exposed to selection by insecticide treatment 10…”

Thirty-nine field populations of Frankliniella occidentalis (Pergande) were collected from different crops (sweet pepper, tomato, lettuce, artichoke, melon, cucumber, carnation, broad bean, peach and plum) in Murcia (south-east Spain). All populations were reared separately in the laboratory to obtain enough individuals for bioassays. Female thrips were bioassayed, using a standard topical application method, against methiocarb, methamidophos, acrinathrin, endosulfan, deltamethrin and formetanate. Methiocarb was the only insecticide that showed a high efficacy against F occidentalis at field dose rates. Acrinathrin and methamidophos were moderately effective, while endosulfan and deltamethrin were ineffective. Only moderate levels of resistance (Resistance Ratios at LC50 of 10-30) were detected for the selective insecticides methiocarb, formetanate and acrinathrin used against F occidentalis in crops where these insecticides are used intensively. This generalized and low level of resistance to these insecticides, coupled with a lack of efficacy for the three broad-spectrum insecticides, was observed even in intensively managed vegetable crops. Implementation of IPM strategies in Murcia has contributed to more successful insecticide anti-resistance management.

“…It is highly polyphagous and transmits viruses to 550 species from more than 60 families in California (Robb and Parrella 1995). Successful thrips control in ornamental crops is rare, aesthetic damage is important and pest tolerance is extremely low, particularly if the crop is destined for export (Parrella 1995).…”

Effects of contrasting diets and temperatures on reproduction and prey consumption by Proprioseiopsis asetus (Acari: Phytoseiidae)

et al. 2008

Proprioseiopsis asetus (Chant) (Acari: Phytoseiidae) is a relatively unknown predacious mite with potential as a biological control agent of Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) and Tetranychus urticae Koch (Acari: Tetranychidae). In this study, the developmental rate and other biological parameters of P. asetus were investigated. Development of P. asetus was temperature dependent from 10 to 40 degrees C. Nonlinear models were fitted to development rate (1/time) data from egg to adult and by sex to estimate development times. The model of Sharpe and De Michele (1977) best fits the developmental data. The shortest development time on cattail (Typha latifolia (L.)) pollen occurred at 35 degrees C for all stages except for the egg stage, for which it was longer. The optimum development time at 35 degrees C is above the temperature optimum of most phytoseiid mites. Fecundity increased when P. asetus mated more than once. Males were needed at all times for maximum oviposition, although their consumption was negligible. Oviposition, prey killed (Franklinella occidentalis or T. urticae) and longevity of P. asetus females were recorded in the presence of males. Egg production increased with number of prey killed and P. asetus has the characteristics of successful predators of thrips.

“…Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) remains one of the most important pests of protected cultures world‐wide (Shipp et al., 1991; Robb & Parrella, 1995; Tommasini & Maini, 1995; Lewis, 1997). As a generalist phytophagous species, F. occidentalis feeds on a wide range of crops of economic importance, both in the field and in glasshouses (Yudin et al., 1986; Brødsgaard, 1989; Tommasini & Maini, 1995).…”

The life cycle of the Western Flower Thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), one of the most important glasshouse pests, includes a soil passage composed of three instars that deserve more attention in terms of biocontrol strategies. It has been repeatedly reported that two polyphagous predatory mites, Stratiolaelaps miles (Berlese) and Hypoaspis (Geolaelaps) aculeifer (Canestrini) (Acari: Laelapidae), also prey on these thrips stages, in addition to several other soil inhabiting prey species. However, the potential thrips consumption rates have never been quantified for these predatory mites. Therefore, an arena experiment was carried out to investigate the potential predation rates of the two mites on second instar larvae, prepupae, and pupae of F. occidentalis. In addition, the fecundity on the thrips diet was assessed and compared to oviposition rate on a nematode prey. All thrips instars were accepted as prey by each mite species. Females of H. aculeifer preyed on 3.5 (± 0.5) thrips instars and laid 2.5 (± 0.87) eggs per day, whereas females of S. miles preyed on 1.64 (± 0.3) thrips and laid 0.8 (± 0.53) eggs. Males of both species killed 0.6 (± 0.3) thrips per day. The fitness of the two predatory mites on F. occidentalis as prey and their suitability as biocontrol agents are elucidated. Reasons for reduced thrips control in the soil environment, in contrast to the results obtained in arena assays are discussed.
