The Caribbean fruit fly, Anastrepha suspensa (Loew), has also been called the Greater Antilliean fruit fly, the guava fruit fly and the Caribfly. It is a near relative of the Mexican fruit fly, Anastrepha ludens (Loew), and is one of several species of fruit flies which are indigenous to the West Indies and the larvae of which attack several kinds of tropical and subtropical fruits. This document is EENY-196 (originally published as DPI Entomology Circulars 38 and 260), one of a series of Featured Creatures from the Entomology and Nematology Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

AbstractAfter oviposition, females of the Mediterranean fruit fly Ceratitis capitata Wiedemann deposit a host-marking pheromone on the fruit surface that deters oviposition by conspecifics. Methanolic extracts of fruit fly faeces elicit a similar deterrent effect. The results of laboratory and field experiments using raw methanolic extracts of C. capitata faeces as an oviposition deterrent are reported. Laboratory bioassays revealed a significant positive relationship between concentration of faeces and the inhibition of oviposition responses by C. capitata. Treatment of halves of coffee bushes with methanolic extracts containing 0.1, 1.0 and 10 mg faeces ml−1 resulted in a significant reduction of infestation only at the highest concentration (P = 0.03). Treatment of blocks of coffee bushes with an extract of 10 mg faeces ml−1 resulted in an 84%reduction in infestation by C. capitata in sprayed plants and a 56% reduction in adjacent untreated coffee bushes surrounding treated plots, probably due to the deterrent effect of host-marking pheromone on fly oviposition. We conclude that faeces contain oviposition deterrent substances that effectively reduce fruit infestations by C. capitata, suggesting a clear potential for the use of this infochemical in integrated management programmes targeted at this pest.

Percent electrolyte leakage, a measure of membrane integrity, proved to be a good predictor (R2 = 0.99) of cobalt-60 gamma irradiation dose injury on mid-season ‘Ruby Red’ grapefruit Citrus paradisi (Macf.) flavedo tissue (peel). Percent electrolyte leakage on grapefruit peel following a dose-rate of 250 grays/1.0, 2.5, 5.0, and 25.0 min decreased as grays/min (dose-rate) decreased. Total phenols, a biochemical response to irradiation following 250 grays/1.0, 2.5, 5.0, and 25.0 min also decreased as dose-rate decreased, demonstrating that injury to grapefruit peel diminished as 250 grays of gamma irradiation/rate declined. Comparisons of 10 and 20 grays of cobalt-60 gamma irradiation showed that a dose-rate of 10 grays/0.25 min to naked 8-d old Mexican fruit fly Anastrepha ludens (Loew) larvae caused a 90% reduction of adult emergence. Whereas, at 20 grays the reduction was greater than 99% with dose-rates of 20 grays/0.25, 0.5, 1.0, or 100 min. These data show that a gamma irradiation dose capable of reducing fly emergence by >99% will maintain an inhibitory effect even at relatively lower dose-rates. Therefore, once a quarantine security treatment for Mexican fruit fly is established, a lower dose-rate will reduce adult emergence and should impart little damage to grapefruit peel tissue.
