fruit flies are serious pests of Mango in Sudan; they cause substantial damage to Mango production, both qualitatively and quantitatively. This study is an effort to establish information about the pest and, to test the susceptibility of some Mango cultivars （Baladi, Kitchener, Shendi, Alphons, Abu Samaka and Bit abusamaka） to the pest infestation. A survey was carded out at Shendi area, River Nile State, during the period of May 2007 to July 2008, using a home made trap resemble lvnfield traps with attractants （Methyl eugenol, Trimedlure, cue lure and Nu lure） to identify the fruit flies species found in the area and to study the seasonal abundance of the pest species and to determine the infestation percentage of different Mango cultivars. Results indicated that the fruit fly Bactrocera invadens is present all year-round in the study area, with population peak July to September. The study showed that Guava （ Psedium guajava ） represents the best alternative host for the pest. Abu samaka and Bit Abusa amaka mango cultivars were the most susceptible, with 100% infestation, followed by Shendi 70%, Kitchener 54%, Alphons and Baladi （30%, 28%, respectively） were the least susceptible. Also results revealed that females of both species Ceratitis cosyra and Bactrocera invadens out numbered males 4-5 times.

Research on fruit fly courtship has mostly focused on males＇ behavioral repertoire whereas females have been as- sumed to respond by either rejecting or accepting males. In many fruit fly species including Drosophila melanogaster, however, mating typically follows an extended period of courtship, which provides ample opportunities for females to inform males about their likelihood of mating. Our experiments indeed revealed that sexually immature females in both D. melanogasterand D. si- mulans showed responses to conspecific males that were distinct from those of sexually mature females. Furthermore, females＇ responses to conspecifie males were different from their responses to heterospecific males. Our data indicate that females＇ beha- vioral repertoire early in courtship can inform males about their probability of mating if they persist in courting. We hypothesize （i） that males can rely on behavioral feedback from females for optimally allocating their courtship efforts towards distinct female classes, （ii） that males may learn to modulate their courtship behavior based on specific feedback from females, and （iii） that fe- males may learn to alter their behavior towards distinct types of males in order to elicit the desired male response. Overall, we suggest that, although little explored, female behavior determines the dynamics of courtship and mating and can thus influence sexual selection and incipient speciation .

The effect of （1-（4-chlorophenyl）-3-（2,6-difluorobenzoyl）urea） insecticide - diflubenzuron - on wild type and white type fruit flies Drosophila melanogaster （Meigen, 1830） was studied. Adult insects were placed in vials with different concentrations of the insecticide in the nutrient （from 0.048 to 48 mg of diflubenzuron per 1 cm^3 of the nutrient）. In each case, the insects showed some mortality, which was concentrationdependant. When comparing both strains, we could observe different acute toxicities, with wild type being more resistant to diflubenzuron. However, subacute toxicity was similar within both strains. In both strains the prolonged exposure led to the extinction of the majority of the populations （〉 70%）. Although imagoes could freely copulate, we did not observe copulating fruit flies, and we did not find either eggs or larvae in any of the exposed groups. These results indicate that genetic mutation which leads to different eye colour can also affect resistance and survival of insects in pesticide-exposed areas.

fruit flies are causing extensive socio-economic losses in citrus orchards in Ghana. The flies as quarantine pests have detrimental effects on the export market due to international trade regulations. Oecophylla species have been tested as biological control agents on other crops, and have shown great potential in reducing the effects of pests. The effectiveness of Oecophylla as a biocontrol agent of fruit flies was compared with insecticide, Cypermethrin ＋ Dimethoate （Cydim super~） at Forest and Horticultural Crops Research Centre, Kade, in the Eastern Region of Ghana. The results have shown that trees colonized by Oecophylla had between 6%-10% fly infestation and Cypermethrin ＋ Dimethoate （1614 mg a.i. mL~ tree＂1） recorded 3.0% infestation. Cypermethrin ＋ Dimethoate treatment recorded 3.50 ~ 0.87 dropped fruits, and Oecophylla colonized-trees recorded 15 to 19.20 -4- 3.61. Oecophylla colonized-trees recorded yield values from 12.90 to 15.20 tons ha-~ whilst Cypermethrin ＋ Dimethoate treatment recorded 27.90 tons hat fruit yield. Total number of fly landings in the presence of Oecophylla （72.00） was significantly lower than the absence of Oecophylla （114.20）. Set-up with no Oecophylla recorded the highest infestation index （71.17） while the presence recorded 45.83. These results suggest that Oecophylla longinoda can be used as a biocontrol agent for IPM programs in citrus orchards.

Mango is the third largest export fruit in Cote d’Ivoire. However, its yield is limited by the damage caused by fruit flies （Diptera： Tephritidae）. This study aimed at assessing the trapping system for fruit fly detection and monitoring in mango orchards in Northern C？te d’Ivoire. Four sites were selected in Northern C？te d’Ivoire in mango production area and in timber yard areas. Five trapping systems were tested： two food attractants （torula yeast, CeraTrap） and three sex attractants （methyl eugenol, trimedlure, cue-lure）. Plastic bottles were used for food attractants and commercial traps for sex attractants. Five traps per treatment with three repetitions per site were set up. Ten species of flies have been identified： Bactrocera dorsalis, B. cucurbitae, Ceratitis anonae, C. bremii, C. capitata, C. cosyra, C. punctata, Dacus ciliatus, D. punctatifrons and Dacus spp.. Among these species, B. dorsalis was dominant. It was captured by 94.04% and 90.94%, respectively, in mango orchards and forest areas included wild fruits. The average number of individuals captured varied from one species to another, depending on the attractants. This average was estimated to 379.91, 27.58, 25.55, 15.1 and 11.93, respectively, for méthyl eugénol, torula yeast, CeraTrap, cue-lure, trimedlure. The attractants have shown their specificity in capturing fly species. Methyl eugenol had the highest capture and was the most effective.
