Jaburetox induced in vivo hemocyte aggregation. Fifth-instar nymphs (7 days after ecdysis) were injected with PB (controls) or with Jaburetox in a dose of 2 μg/insect. Six hours later, the hemolymph was collected and diluted with anticoagulant solution. The number of aggregates (a) and free cells (b) was counted using a hemocytometer. The values are expressed as the number of aggregates or the number of free cells per ml of hemolymph. Mean ± SEM (n = 4 for controls and n = 6 for Jaburetox-treated insects). **P < 0.01 vs control
