Repellent screening of ethanol extracts from plants of the Yucatan Peninsula against Bemisia tabaci (Gennadius, 1889) and chemical profile of Malpighia glabra L. leaves

The whitefly Bemisia tabaci (Gennadius, 1889) (Hemiptera: Aleyrodidae) is a globally important insect pest, causing extensive damage and losses in horticultural production systems. New natural options are needed to control the whitefly. Ethanol extracts (92) of different organs from 40 plant species of the Yucatan Peninsula were evaluated against B. tabaci in a greenhouse, and an adult repellency index (RI) was determined for leaves and an oviposition deterrence index (ODI) for the extracts.
