Abstract The greenhouse cucumber pests, Bemisia tabaci (Hemiptera: Aleyrodidae), Frankliniella occidentalis (Thysanoptera: Thripidae), and Tetranychus urticae (Acari: Tetranychidae), are major threats to the production of greenhouse cucumbers (Cucurbitaceae) in Lebanon. The development of insecticide resistance by these pests has prompted the use of alternative and sustainable pest management strategies. In this study, we used integrated pest management strategies, including the release of the biological control agents, Amblyseius swirskii Athias-Henriot (Mesostigmata: Phytoseiidae) and Phytoseiulus persimilis Athias-Henriot (Mesostigmata: Phytoseiidae), to control whitefly, thrips, and two-spotted spider mite populations on greenhouse cucumber plants in two commercial production sites (sites A and B). We also compared the efficacy of pest population suppression using the integrated pest management strategy with that of chemical pest control. Our results show that biological control effectively maintains the cucumber pest populations below the economic threshold when coupled with additional integrated pest management measures. In addition, we show that biological control agents were equally or more effective in pest population suppression compared to eight and 12 insecticidal and acaricidal sprays performed in the control greenhouses at sites A and B, respectively. Altogether, our results show the efficacy of adopting integrated pest management and biological control for pest population suppression in greenhouse cucumber production under Mediterranean environmental conditions.

Species Being

Phytoseiidae (Acari: Mesostigmata) is an important family of predatory mites, with some species being commercialized as biological control agents for the control of phytophagous mites and small insects. In Peru, 65 species of this family have been recorded so far, with Amblyseius being the most diverse genus, with 11 species. The aim of this study is to report for the first time the presence of Amblyseius tamatavensis Blommers, 1974 in Peru. In South America, this species has so far been reported only in Brazil and Venezuela. In Peru, A. tamatavensis was found on orange plants [Citrus sinensis (L.) Osbeck] in the district of Pangoa, department of Júnin. In the laboratory, collected specimens were observed to feed on Phyllocoptruta oleivora (Ashmed, 1879) (Acari: Eriophyidae) and Frankliniella occidentalis (Pergande, 1895) (Thysanoptera: Thripidae). Studies to verify the potential of this species as a biological control agent for pests occurring in Peru should be conducted. A key to the Amblyseius species recorded in Peru is presented.

In this study, we examined biological control Thirps palmi Karny of a predatory mite Amblyseius (Typhlodromips) swirskii (AthiasHenriot), the anthocorid bug Orius sp. and combination of Amblyseius swirskii and Orius sp. The experiments in laboratory condition showed that combination of these two species have the ability to prey consumtion is higher than using only predator (Orius sp. or Amblyseius swirskii). The fecundity of Orius sp. in the absence of Amblyseius swirskii (the total number of eggs/ females = 45.5 ± 2.25 eggs, the oviposition period = 16.49 ± 0.5 days) were higher than in the presence of Amblyseius swirskii (the total number of eggs/ females = 35.6 ± 2.33 eggs, the oviposition period = 13.1 ± 0.63 days). Similar with Amblyseius swirskii, the fecundity of Amblyseius swirskii in the absence of Orius sp. (the total number of eggs/females = 35.57 ± 3.62 eggs, the oviposition period = 21.33 ± 0.7 days) were higher than in the presence of Amblyseius swirskii (the total number of eggs/ females = 24.1 ± 1.67 eggs, the oviposition period = 13 ± 1.43 days). In the greenhouse with area of 300m2, the experiments were conducted when used two-predator were average aduts (Orius sp. were 3.47 adult/ leaf, A. swirskii were 6.96 adult/ leaf) were aqual as release of only Orius sp. (average adult = 3.81 adult/ leaf) or only Amblyseius swirskii (average adult = 6.49 adult/ leaf). This study also provides further evidence that intraguild predation does not necessarily have negative effects on biological control.

Amblyseius swirskii Athias-Henriot (Acari: Phytoseiidae) is a commercially available predatory mite used to control thrips, whiteflies, and broad mites in horticultural production. The inconsistent quality of mass-produced biocontrol agents is a major concern in augmentative biological control and only a few studies have tested the post-shipment quality of commercial phytoseiids. We evaluated the post-shipment quality of A. swirskii purchased from a commercial provider in the United States. Guidelines for quality control of commercially produced natural enemies, established by the International Organization for Biological Control (IOBC), were followed. Quantity, survival, fecundity, and establishment in ornamenttal peppers (‘Explosive Ember’) were measured. The estimated quantity of A. swirskii motiles (immatures and adults) was quite variable among bran containers (20,968 ± 7,391 mites) but close to the number claimed in the label. Numbers of living A. swirskii females evaluated (n = 30) declined by less than 40% (26 ± 1.25 females) within two days of arrival and declined more than 50% by day eight (15 ± 1.23 females). No significant differences among days sampled were identified for female fecundity; however, fecundity varied considerably among containers. There was no population increase in the ornamental peppers during the two weeks following inoculation with A. swirskii. Accepted for publication 3 September 2016.

In the late 1970s, Brazilian peppertree, Schinus terebinthifolia Raddi (Sapindales: Anacardiaceae), was targeted for classical biological control in Florida because its invasive properties (see Host Plants) are consistent with escape from natural enemies (Williams 1954), and there are no native Schinus spp. in North America. The lack of native close relatives should minimize the risk of damage to non-target plants from introduced biological control agents (Pemberton 2000). [...]
