dc.description.abstractThe objective of this study was to determine the influence of Metarhizium anisopliae on the predatory capacity and functional response of Chrysoperla externa fed Bemisia tabaci B biotype rearing cotton. The stock rearings of B. tabaci B biotype and C. externa were maintained in cages according to preexisting methodologies. Upon hatching, predator larvae were fed on eggs of Ephestia küehniella until their 3rd instar and then fed on whitefly nymphs in density exceeding their intake capacity (150 nymphs/individual). The nymphs were offered on cotton leaf disks (5 cm diameter), 24 hours after the treatments application following: T1: Control (water); T2: M. anisopliae at the concentration of 105 conidia cm-3; T3: 10 8 conidia cm-3 origined from Metharril® formulation of the 109 viable conidia cm-3 M. anisopliae active principle. The predatory capacity was obtained by the difference between the numbers of nymphs supplied and nymphs left. Five different nymphal densities (130, 160, 190, 220, and 250) were selected for the functional response study. The number of nymphs preyed was recorded after 24, 48, 72, and 96 hours. The M. anisopliae entomopathogenic fungi did not influence predatory capacity of C. externa which ranged from 70.6 individuals at the highest concentration to 87.1 in the control. Conclued that the C. externa predatory capacity was not affected by fungi M. anisopliae concentrations. The predator showed a type-II functional response after 24 hours, and a type-I response after 48, 72s, and 96 hours independent from fungi concentrations.en
