The potential of a lady beetle, Nephaspis oculatus (Blatchley), to serve as a biological control agent of the sweetpotato whitefly, Bemisia tabaci (Gennadius) Biotype “B” (= B. argentifolii Bellows & Perring), was evaluated on hibiscus under confined conditions, in large cages (60 × 60 × 60 cm) and on sweetpotato leaves in small clear cup cages (0.9 L). Nephaspis oculatus suppressed B. tabaci populations and provided marketable hibiscus plants when released 1 d after whitefly introduction in large cages at ratios of 1:4 and 1:20 beetle:whitefly. When beetles were released 7 d after the whitefly infestation, significant pest reduction and marketable plants were obtained with the 1:4 beetle:whitefly ratio but not the 1:20 ratio. In clear cup cages on sweet potato leaves, significant suppression was obtained at beetle:whitefly ratios of 1:6.7, 1:10 and 1:20 when N. oculatus was released 1 d after the whitefly infestation. These results help define release parameters for successful use of N. oculatus as a biological control agent of whiteflies under confined conditions.

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.

A 2-year demonstration study was conducted to compare the effectiveness of two sources of Encarsia formosa (EF) on the biological control of the sweetpotato whitefly (SPWF) (Bemisia tabaci Gennadius) on poinsettias (Euphorbia pulcherrima Wild.). Commercially produced EF were raised on the greenhouse whitefly (GHWF) (Trialuerodes vaporariorum Westwood), while the locally produced EF were raised on the SPWF. Results showed that SPWF populations were reduced considerably both years, and maximum nymph parasitism ranged from 60% to >80%. No large differences were observed in the ability of EF to control SPWF populations whether raised on SPWF or GHWF nymphs. This study suggests that there is potential for controlling SPWF populations on poinsettia by EF in conjunction with an integrated pest management (IPM) program.

Female Fecundity

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.
