Abstract
Whiteflies are considered the most serious insect pest in greenhouse poinsettias.
Research on alternative strategies to chemical control has successfully introduced the biocontrol with parasitoids.
Shipping cost of parasitoids is the main constraint for the diffusion of biocontrol.
This experiment was conducted to evaluate the effectiveness of concentrated releases of parasitoids for pest control on poinsettia grown in greenhouse, in order to induce an early biocontrol of the whiteflies Bemisia tabaci and Trialeurodes vaporariorum and reduce shipping costs.
Two biological products were used: one with both Encarsia formosa and Eretmocerus spp. and the other with an E. formosa strain able to control both B. tabaci and T. vaporariorum. The parasitoid treatments were compared with a chemical control (thiamethoxam) and with a non-treated test.
Results showed that during poinsettia cultivation whitefly control with 4 concentrated releases was not significantly different from the traditional 8 releases program.
No differences in the effectiveness of the two biological products used were observed.
A single drenching treatment with thiamethoxam 6 weeks after potting was very effective in controlling whiteflies.
At the end of the trial the effectiveness of biological products was similar to the chemical treatment in adult whiteflies control.
Nymph whiteflies biological control was slightly beyond the economic threshold of 2 live nymphs per leaf.
