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.

AbstractThe sterile insect technique (SIT) is widely used in integrated pest management programs for the control of the Mediterranean fruit fly (medfly), Ceratitis capitata. The genetic interactions between the released individuals from the genetic sexing strains (GSS), used for SIT applications worldwide, and wild individuals have not been studied. Under the hypothesis that a number of Vienna GSS individuals released to the field might not be completely sterile and may produce viable offspring, we have analyzed medfly Spanish field populations to evaluate the presence of Vienna strain genetic markers. To this goal, we have used contrasted nuclear and mitochondrial genetic markers, and two novel sets of nuclear polymorphisms with the potential to be markers to discriminate between Vienna and wild individuals. Nuclear Vienna markers located on the 5th chromosome of Vienna males have been found in 2.2% (19 from 875) of the Spanish wild medfly females captured at the area where SIT is applied. In addition, a female-inherited mitochondrial Vienna marker has been found in two from the 19 females showing nuclear Vienna markers. The detection of several of these markers in single individuals represents evidence of the introgression of Vienna strain into natural populations. However, alternative explanations as their presence at low frequency in wild populations in the studied areas cannot be fully discarded. The undesired release of non-fully sterile irradiated GSS individuals into the field and their interactions with wild flies, and the potential environmental implications should be taken into account in the application of the SIT.

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.

A newly discovered species of tephritid, Dacus (Bactrocera) opiliae Drew & Hardy, is almost indistinguishable morphologically from the Oriental fruit fly, Dacus dorsalis. and was originally believed to represent an invading population of that species. Breeding by D. opiliae is virtually restricted to the fruit of the native vine Opilia amentacea throughout coastal areas of the Northern Territory and the Kimberleys region of Western Australia. The phenology of the host and aspects of its utilization by D. opiliae are described. Fruit suitable for oviposition is available only for a short period each year from late November to early January. It is shown that D, opiliae is effectively univoltine. Although it was able to infest various cultivated fruits in the laboratory, no evidence of such infestations by natural populations of D. opiliae was recorded during this study and the species seem to present no threat to Australia's fruit-growing industries. Information on host relations of D. jarvisi (Tryon), D. aquilonis (May) and D. tenuifascia (May) is also presented.

The present study constitutes the first attempt to construct a polytene chromosome map of an Anastrepha species, Anastrepha ludens (Loew), a major agricultural pest. The mitotic karyotype has a diploid complement of 12 acrocentric chromosomes, including five pairs of autosomes and an XX/XY sex chromosome pair. The analysis of salivary gland polytene chromosomes has shown a total number of five polytene elements that correspond to the five autosomes. The characteristic features and the most prominent landmarks of each chromosome are described. By comparing chromosome banding patterns, the possible chromosomal homology between A. ludens and Ceratitis capitata (Wiedemann) is presented. This work shows that polytene maps of A. ludens are suitable for cytogenetic studies in this species and may be used as reference for other Anastrepha species, most of which are also serious agricultural pests.

Knowledge of the influence of evolutionary factors that promote either the differentiation or cohesion of pest insect populations is critical for the improvement of control strategies. Here, we explore the extent to which genetic differentiation occurs between populations of the Mexican fruit fly, Anastrepha ludens, in association with four plant hosts (Citrus sinensis, C. paradisi, Mangifera indica and Casimiroa edulis) in the Soconusco region of Chiapas (Mexico). Using variants from six enzymatic loci, we obtained measures of genetic diversity for three sample arrangements: (1) by sex per locality, (2) by locality and (3) by host. The extent of genetic differentiation in populations was assessed using the Analyses of Molecular Variance (AMOVA) method for each array of samples, and moderate to high levels of genetic variation were observed between the sexes, as well as among localities and host plants. A Bayesian approach was then used to assess any population structure underlying the genetic data we obtained, but this analysis showed no significant structuring due to locality or host plant. We also considered whether the observed genotypic frequencies in male and females matched those expected under a hypothesis of random mating. Here we found significant deviations from expected genotypic frequencies, suggesting that sexual selection is acting on these populations. Overall, our results indicate that sexual selection, along with the presence of some heterogeneity in environments provided by both geographical factors and availability of host plants, has influenced the evolution of pest populations in this region of Mexico. Implications for area-wide pest management strategies are discussed.
