First Record of Conotrachelus quadrilineatus Champion, 1904 (Coleoptera: Curculionidae: Molytinae) Damaging Beans in South America.

Common bean (Phaseolus vulgaris L.) is the most important legume used for direct human consumption in Latin America, with an increasing expansion of cultivated areas in recent years. Here, we report the first occurrence of Conotrachelus quadrilineatus Champion, 1904 (Coleoptera: Curculionidae: Molytinae) feeding on bean in South America.

Performance of Amblyseius herbicolus on broad mites and on castor bean and sunnhemp pollen.

Amblyseius herbicolus (Banks) is found associated with broad mites Polyphagotarsonemus latus in crops such as chili pepper in Brazil. The species has a potential for controlling P. latus, but little is known about its development and reproduction on this pest as well as on other food sources.

Lime sulfur toxicity to broad mite, to its host plants and to natural enemies.

Background: An acaricidal effect of lime sulfur has not been demonstrated for Polyphagotarsonemus latus. However, lime sulfur can cause toxicity to natural enemies and to host plants. In this study, the toxicity of different concentrations of lime sulfur to P.
