Pathogenicity of the entomopathogenic fungus Metarhizium anisopliae to the red-legged tick, Rhipicephalus evertsi evertsi

  Rhipicephalus evertsi evertsi is an economically-important tick of livestock in Africa mainly due to its ability to transmit Babesia equi to horses, Anaplasma marginale to cattle and to cause paralysis in lambs, adult sheep and calves.

Pseudomonas fluorescens as an efficient entomopathogen against Oligonychus coffeae Nietner (Acari: Tetranychidae) infesting tea

  The biocontrol efficacy of the bacterium, Pseudomonas fluorescens was evaluated against the red spider mite (RSM), Oligonychus coffeae in laboratory. Both bacterial suspension and extra cellular filtrate of 24, 48 and 72 h old were sprayed to test the efficacy of bacterium against adult mites. The mortality due to P. fluorescens increased as the age and percentage of culture...
