AbstractAdult apple maggots, Rhagoletis pomonella (Walsh), were relatively free from attacks by predators in southern Ontario. The main reason for this was the flies’ alert avoidance of approaching objects. In addition to this protection from predators, the flies appeared to be avoided by hunting spiders. Adults of the cherry fruit fly, Rhagoletis cinqulata (Loew), were equally alert and apparently free from predation while they were in apple trees.

Larvae of two closely related species of fruit flies in central and eastern North America -- Rhagoletis cingulata (Loew), commonly called the cherry fruit fly or cherry maggot, and Rhagoletis fausta (Osten Sacken), the black cherry fruit fly -- attack cherry and cause wormy fruits. Only R. cingulata occurs in Florida, where it attacks wild cherries and is of little economic importance. These two species closely resemble a third pest species, the apple maggot, Rhagoletis pomonella (Walsh); the adults of all three have banded wings. R. cingulata breeds in all varieties of cherries including the sweet cherry. This document is EENY-203 (originally published as DPI Entomology Circular 116), 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.

Tephritidae are the true fruit flies, which include the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), the walnut husk fly, Rhagoletis completa Cresson, the Mexican fruit fly, Anastrephaludens (Loew), and the apple maggot fly, Rhagoletis pomonella (Walsh). Fruit fly infestation causes major damage to many economically-important food crops and is of major concern in agriculture worldwide.Tephritidae are controlled primarily by repeated applications of organophosphate pesticides. Health concerns, environmental pollution, and costs associated with pesticide use press researchers to find new methods for control. One approach to finding new control methods involves investigating the associations that exist between tephritids and microorganisms. Currently, bacterial odors are being used to lure these pest tephritids into traps. These flies are specifically attracted to odors from certain bacteria found to inhabit their gut. Data suggest that these bacteria are likely involved in important aspects of fruit fly nutrition and reproduction.

Biological Studies

During the past decade the attractiveness of various hydrolyzed proteins to several species of tephritid flies has been established and these materials have been used in poison bait sprays, in fly traps, and in studies on dispersal habits. Several workers have reported more satisfactory control when enzymatic yeast hydrolysates or acid hydrolysates of corn protein were added to malathion sprays: Steiner (1952, 1955a, and 1955b) for the Mediterranean fruit fly (Ceratitis capitata Wied.), the oriental fruit fly (Dacus dorsalis Hendel), and the melon fly (Dacus cucurbitae Coq.); Shaw (1955) for the Mexican fruit fly (Anastrepha ludens Loew); Orphanidis et al. (1958) for Dacus adults on olives; and Marucci (1958) for the blueberry maggot (Rhagoletis pomonella (Walsh). Orphanidis et al. have also reported that the addition of casein hydrolysate or the acid hydrolysates of corn protein to the recommended lure of ammonium sulphate increased the captures of Dacus as much as twelve times. Although most of the work with these attractants has concerned control, Barnes (1959) has used them to advantage in biological studies. He labelled natural populations of the walnut husk fly, Rhagoletis completa Cress., with a radioactive tracer by attracting the flies to feeding stations of Staley's insecticide bait No. 7 (acid hydrolysate of corn protein) plus the isotope P32 By subsequent trapping he determined the field movements of the adults in and out of walnut orchards.

AbstractNone of five mixtures of protein hydrolysate and azinphosmethyl which were applied as foliar sprays (1.0, 2.0, 5.0% yeast hydrolysate, 2.0% corn hydrolysate, and 2.0% soy hydrolysate) killed significantly more apple maggot flies, Rhagoletis pomonella, or black cherry fruit flies, R. fausta, than a spray of azinphosmethyl alone which was used as a control. This suggests that hydrolysate bait sprays would be no more effective than a toxicant alone in controlling these flies.

Host Plant Shift

Changes in behaviour often drive rapid adaptive evolution and speciation. However, the mechanistic basis for behavioural shifts is largely unknown. The tephritid fruit fly Rhagoletis pomonella is an example of ecological specialization and speciation in action via a recent host plant shift from hawthorn to apple. These flies primarily use specific odours to locate fruit, and because they mate only on or near host fruit, changes in odour preference for apples versus hawthorns translate directly to prezygotic reproductive isolation, initiating speciation. Using a variety of techniques, we found a reversal between apple and hawthorn flies in the sensory processing of key odours associated with host fruit preference at the first olfactory synapse, linking changes in the antennal lobe of the brain with ongoing ecological divergence. Indeed, changes to specific neural pathways of any sensory modality may be a broad mechanism for changes in animal behaviour, catalysing the genesis of new biodiversity.
