My research focuses on the biological control of the    greenhouse whitefly, Trialeurodes vaporariorum ,  with the    insect predator Dicyphus hesperus and the entomopathogenic    fungus Paecilomyces fumosoroseus Apopka 97 (PFR-97) on    greenhouse vegetable crops

* Picture:Greenhouse whitefly (T. vaporariorum)eggs             * 6 life stages: egg, 4 nymphal instars, adult             * Developmental time at 25 Celcius is 22 days             * Average female oviposition rate is 5.5 eggs/day

* Picture: Dicyphus hesperus Knight             * Omnivorous predator             * Developmental time on whitefly nymphs                is 24 days             * Consumption rate: 20-35 whitefly                nymphs/24 hours

* Picture: Paecilomyces             fumosoroseus Apopka 97          * Manufactured by Certis USA          * Tradename: PFR-97          * Produces blastospores and             conidia

The combined use of Dicyphus hesperus and Paecilomyces fumosoroseus Apopka 97
in biological control programs poses questions as to their associated interactions
with each other and their shared host, Trialeurodes vaporariorum

Therefore, my main goal is to investigate the intraguild interactions between
Dicyphus hesperus, Paecilomyces fumosoroseus Apopka 97, for the
biological control of Trialeurodes vaporariorum
