Resistance of Lima Bean ( L.) to the Red Spider Mite (Acari: Tetranychidae).

The red spider mite, (Acari: Tetranychidae) can be an important pest on lima bean ( L.). Thus, the objective of this work was to assess the antibiosis and antixenosis effects of lima bean genotypes on , through the evaluation of performance parameters as well as the host preference for food and oviposition.

Limitations of Neoseiulus baraki and Proctolaelaps bickleyi as control agents of Aceria guerreronis.

Several predatory mites have been found in association with the coconut mite, Aceria guerreronis Keifer, in northeast Brazil. However, the latter still causes damage to coconut in that region. The objectives of this work were to compare the frequencies of occurrence of Neoseiulus (Phytoseiidae) and Proctolaelaps (Melicharidae) species on standing and aborted coconuts in coastal Pernambuco State, northeast Brazil and to analyze their possible limitations as control agents of the coconut mite, based on evaluations of the restrictions they may have to access the microhabitat inhabited by the pest and their functional and reproductive responses to increasing densities of the latter.
