Effects of pesticides on pests affecting tropical fruit

Jorge E. Pena, Rita E. Duncan, Charles W. Meister

Abstract


Selected pesticides were evaluated for control of the spider mites (Tetranychus spp.,) infesting bananas, sri-lankan weevil (Myllocerus undecimpustulatus) infesting mangoes, armored scales (Andaspis punicae and Chrysomphalus dyctiospermi) infesting mangoes, and Persea mite (Oligonychus perseae) infesting avocados. A. punicae has an armor usually covered with the outer layers of the bark and regularly is located near lenticels. C. dyctiospermi is an economic pest in Florida to fruit and ornamentals. Myllocerus undecimpustulatus is a weevil introduced into the USA during 2000, and it has since spread to different counties in the state, causing damage to fruit crops and ornamentals. The Persea mite, Oligonychus perseae, is native to Mexico. It was discovered in Miami–Dade County during June 2007. Spider mites, Tetranychus spp., cause damage to the foliage of bananas. All trials were conducted at the Tropical Research and Education Center. We discuss the effectiveness and shortcomings of the tested products.
