“…Ladybird beetles, Menochilus sexmaculatus Fabricius and Coccinella transversalis Fabricius, and entomopathogenic fungus Lecanicillium lecanii R. Zare & W. Gams are potential natural enemies of Thrips parvispinus. The use of M. sexmaculatus and L. lecanii was as effective in controlling Thrips parvispinus and increasing the yield of the crop (Prabaningrum et al 2008). Microbial biopesticides such as Pseudomonas fluorescence NBAIRPFDWD or Bacillus albus NBAIR-BATP are also effective in suppressing Thrips parvispinus when sprayed on flowers and fruits .…”

“…Menochilus sexmaculatus (Coleoptera: Coccinellidae) is widely distributed in the world and is known to be an important predator of many insects such as aphids, thrips, and whitefly (Bari and Sardar 1998;Ulrichs et al 2001;Setiawati et al 2005;Prabaningrum et al 2006;Rana 2006;Solangi et al 2007;Jagadish et al 2010). The study aimed to evaluate the effects of M. sexmaculatus as biocontrol agent of B. tabaci on tomato and its effect on gemini virus infestation.…”

Bemisia tabaci (Genn.) (Homoptera: Aleyrodidae) is one of the most serious pests on tomato. It is mainly controlled by chemical means, requiring some 25 sprays during the average growing season. The extensive and repeated use of insecticides has disrupted the natural balance between this pest and its natural enemies. In this study, Menochilus sexmaculatus F. was evaluated as a possible biological control agent of B. tabaci and its effect on gemini virus infestation. The study was conducted at the experimental station of the Indonesian Vegetables Research Institute (IVeGRI) in Lembang, West Java (1,250 m above sea level) from August to December 2008. The experimental plots consisted of 0.35 ha of tomato (± 100 m 2 per plot) and spatially separated with four rows of maize (a minimum of 1 m) interplot distance to prevent cross-contamination among plots. The experiment was arranged in completely randomized block design with eight treatments and four replications. M. sexmaculatus were released at 24 days after planting. The treatments were designed according dosages and schedules at three released populations (i.e. 10 predators per plot, 20 predators per plot, and 10 predators per plot at vegetative stage followed by 20 predators per plot at generative stage); two places of release (center and edge of the plot); and two schedules of release (weekly and biweekly). Efficacy of the predator was measured in terms of the density of B. tabaci, both before and after release of the predator and its effect on gemini virus infestation. The result indicated the potential use of M. sexmaculatus to control B. tabaci and its effect on gemini virus infestation on tomato. Reductions in B. tabaci populations and subsequent tomato yields were significant. B. tabaci population in plots receiving 10 predators showed 73.62% and 75.75% reductions by the end of experiment. The incidence and intensity of gemini virus were consistently and significantly lowest and tomato yield gain was observed when 10 predators were released at weekly intervals. It is suggested that release of M. sexmaculatus against B. tabaci on tomato may be offered as an alternative solution to increase implementation of biologically-based B. tabaci management.
