RESUMO

Locusts occasionally represent a danger in Africa despite intensive management measures, leading to severe yield loss and a commensurate loss of food and money. The laboratory assessment of the toxicity of the Photorhabdus luminescens bacteria and its cell-free filtrate used Schistocerca gregaria nymphs in the second and fifth nymphs as test insects. Greater mortality was seen in locust nymphs of the second and fifth instars due to the high levels of toxicity produced by the bacterial suspension and its cell-free filtrate. The amounts of protein, fat, and carbohydrates in the treated locusts were drastically reduced. For the treated second and fifth instar nymphs of the desert locust, adverse effects on the muscular layers of the midgut and the muscles in the jumping legs were investigated.
