| Abstract: The objective of this work was to evaluate the toxicity, repellency, efficiency, and phytotoxicity of the aqueous extract of juazeiro (Ziziphus joazeiro) leaves in the control of the red spider mite, Tetranychus ludeni, on cotton plant. For toxicity evaluation, T. ludeni adult females were put on cotton leaf discs sprayed with the juazeiro extract. The repellent effect was verified in arenas that contained cotton leaf discs treated or not with the aqueous extract. The control efficiency of the juazeiro extract was evaluated by the infestation of cotton plants by adult female mites, followed by spraying with the extract. Measured LC50 was 3.54% (m/v), with 76.47% mortality and repellent effect. There was control efficiency for 120 hours, with... |

| The aim of this work was to study the population reduction of the tomato leafminer moth, Tuta absoluta (Meyrick), by Pyemotes sp. in the laboratory. The mite became greenish when fed on caterpillars, pupae, and adults of T. absoluta. The caterpillars and adults of T. absoluta were quickly paralyzed by the mite venom. A single T. absoluta could host many Pyemotes sp, physogastric females, which were allowed to grow on the moth. Pyemotes sp. can be a new alternative for the biological control of T. absoluta. However, this possibility must be better understood before it could be recommended, because Pyemotes sp. could also cause dermatitis in the humans. |
