Abstract

Mealybugs (Pseudococcidae) are widely distributed insects that damage a large variety of fruits, vegetables and other crops throughout the world. The soft and thin-skinned fig (Ficus carica L.) is nutritious and tasty. Additionally, these fruits have enormous medicinal potential. Organic farming for the production of fresh figs is in demand. This experiment was designed to determine effective, economic and organic agents to control mealybug infestation on fig orchards. Jatropha (Jatropha curcas) leaf extract, neem (Azadirachta indica) leaf extract and malathion were applied to selected groups of plants at 7, 15, 30, 45 and 60-days intervals and the mealybug densities measured after treatment. Three species (Phenacoccus solenopsis Tinsley, Pseudococcus longispinus (Targioni Tozzetti) and Planococcus ficus (Signoret)) of mealybugs were morphologically identified from experimental fig orchards. Both botanicals and malathion showed an inhibitory effect on mealybugs. The effectiveness against the mealybugs was Malathion > Jatropha leaf extract > Neem leaf extract. Nine biologically active compounds were identified from an LC-MS/MS (Liquid chromatography-mass spectrometry) analysis of Jatropha leaf extract that appear to have insecticidal properties against the mealybugs. We recommend applications of either Jatropha or Neem leaf extracts to fig orchards to control mealybugs every 15 to 30 days.
