The fungus Aschersonia placenta FJSM was evaluated for control of the sweet potato whitefly, Bemisia tabaci. Bemisia tabaci nymphs (1st–4th instars) on tomato plants in the greenhouse (25–27 °C, 70%–85% relative humidity) were sprayed with suspensions containing 0, 104, 105, 106, 107, or 108 A. placenta FJSM conidia/mL. Mortality of fungus-treated 1st to 3rd instar nymphs ranged from 93% to 100% but was <25% for 4th instar nymphs; the fungus sporulated from 70% to 80% of the fungus-treated B. tabaci cadavers. LD50 and LD90 values decreased with time after treatment and increased with instar. LT50 values decreased with conidial concentration. The data were then described with time–dose–mortality models. The results indicate that A. placenta FJSM has potential as a mycoinsecticide for control of B. tabaci.

Sweet Potato Whitefly

Bemisia tabaci (Gennadius) is the most important vector of viruses which cause diseases of “serrano” pepper in southern Tamaulipas, Mexico. This insect is highly attracted to yellow surfaces. When 1,240 yellow traps/ha were uniformly placed in plots, plants with virus symptoms were reduced 61%, 59%, and 15% in 1987/1988, 1988/1989, and 1990/1991, respectively, on the last sampling date yet there was no significant difference in treated and untreated plots. In plots without treatment 78, 91, and 100% of plants exhibit virus symptoms on the last sampling date in the same years, respectively. Plots with traps increased yields of peppers 539%, 202%, and 341% in 1987/1988, 1988/1989, and 1990/1991, respectively, compared to the check. Traps + permethrin at 110 g (AI)/ha reduced populations of B. tabaci adults 78% in the 1987/1988. Permethrin-treated plots without traps increased yields 312% and 366% compared to the control in 1988/1989 and 1990/1991 seasons, respectively. During these same years yield increases were greater than the untreated check when Lambda cyhalothrin, cypermethrin, phosphamidon, dimethoate, naled, Safer™ soap, amitraz, and endosulfan were applied in the same tests.
