Résumé — L'influence de la température sur la croissance in vitro des principales espèces d'hyphomycètes entomopathogènes a été étudiée avec 31 isolats fongiques : 3 souches de Beauveria bassiana (Balsamo) Vuillemin, 3 souches de B brongniartii (= tenella) (Saccardo) Petch, 8

The potential of Metarhizium anisopliae (Metsch.) Sorok. for the control of Frankliniella occidentalis (Pergande) on chrysanthemum cuttings was evaluated in greenhouse experiments. The fungus significantly reduced both the adult and larval populations of F. occidentalis, although the level of control of larval populations was much lower than for adults. Combined application of M. anisopliae and Methomyl (Lannate), however, resulted in a significant reduction of both the larval and adult stages. The use of both control agents might be helpful in reducing the selection pressure for resistance to chemical insecticides, thereby delaying or preventing the build-up of resistant populations in greenhouses.

This chapter discusses the control of termites using biological control agents, such as entomogenous fungi, in Africa.
