Nk. Maniania, A DEVICE FOR INFECTING ADULT TSETSE-FLIES, GLOSSINA SPP., WITH AN ENTOMOPATHOGENIC FUNGUS IN THE FIELD, Biological control, 11(3), 1998, pp. 248-254
Various chamber designs for infecting natural populations of Glossina
pallidipes, G. longipennis, and G. fuscipes fuscipes with the entomopa
thogenic fungus Metarhizium anisopliae were tested in the field. All t
hree species of tsetse flies entered the chambers and became infected
with the fungus. Mortality attributed to infection by M. anisopliae ra
nged hom 0 to 76% for G. pallidipes/G. longipennis and from 0 to 80% f
or G. fuscipes. One design proved to be more efficient than the others
in permitting the passage of flies and contaminating them with fungal
conidia. Dry conidia of M. anisopliae in the infection chamber retain
ed their infectivity for more than 21 days in the held. (C) 1998 Acade
