Population studies and testing of various spraying devices against fruit flies (Dacus dorsalis Hendel) on peach, pear and guava. The results revealed that triangular traps (71.58 males) had captured significantly more population followed by cylindrical traps (38.86 males), PAU fruit fly traps (29.61 males) and spherical traps (21.30 males) in peach; whereas in pear, the number of fruit fly males captured/trap/week were significantly high in triangular traps (127.92 males) as compared to PAU fruit fly traps (55.30 males), cylindrical traps (51.08 males) and spherical traps (42.44 males). The first demonstration site was established in Kamuela, Hawaii, USA. The management of fruit flies at the destructive larval stage is difficult because insecticides in the form of dust or sprays cannot reach till target maggots. At first, the oviposition marks are difficult to detect but as within one to two days the eggs hatch, oviposition marks appear as a distinct spot with a brownish patch around the puncture site. The management of fruit flies (Bactrocera spp.) Fruit rot/ fruit canker**/ algal leaf** and fruit spot** Cultural control: • Prune and destroy the dead twigs and fruits. Sharma K 2012. Crop loss varies from a few per cent to 100% depending on fruit fly population, locality, variety and season (Kumar et al., 2011). in pear with Methyl Eugenol based Traps at different locations in P, Eco-friendly Management of Fruit Flies, Bactrocera spp. 11: Makhmoor, H.D. Fruit flies attack soft, fleshy fruits of a wide variety of fruit and vegetable crops. In 1982 the oriental fruit fly, Dacus (Bactrocera) dorsalis Hendel, was successfully eradicated from the Okinawa Islands, Japan, by a male annihilation method using wood fiberboard squares in which methyl eugenol and naled were incorporated. Studies on the evaluation of the impact of methyl eugenol based different coloured PAU fruit fly traps (16 traps/acre) having male annihilation technique (MAT) in peach, pear, guava and Kinnow revealed that yellow coloured traps had significant impact on the number of males captured and per cent infestation of the fruits. Alamzeb 1990. Many species of fruit flies are considered as high priority quarantine pests in various countries. Qureshi et al. Control options: Cultural. ment practices and land factors for crop yield forecasting The role of different shapes of methyl eugenol based traps in peach and pear were studied at Punjab Agricultural University, Ludhiana, India against major fruit fly species i.e. Mann (1980) advocated the seasonal history and occurrence of B. dorsalis on different fruit crops in Punjab whereas B. dorsalis and B. zonata have been found damaging Kinnow mandarin during August to October (Singh 2006a,b,c, Singh et al., 2013, ... Tephritid fruit flies show strong behavioural responses. The peak fruit fly incidence varied between 31 st to 34 th standard weeks in guava ecosystem at both the locations. 223-26. It completes 5-10 generations in a year in tropical areas and less than 4 in subtropical areas. The fruit flies belonging to order Diptera, sub-order Brachycera, superfamily Tephritoidea (Family: Tephritidae), known as true fruit flies are of great economic importance as majority of them cause extensive damage to many fruits and vegetables and ruin more than 400 different fruit and vegetable crops including mango, guava, citrus, melon, papaya, peach, passion fruit, plum, apple and star fruit (White and Elson-Harris, 1992). IN KINNOW, GUAVA, PEAR AND PEACH, Response of fruit flies, Bactrocera spp. In addition, small numbers of sterile males were released against B. dorsalis. Avoidance of fruit fly infestation is possible by harvesting crops at a stage of maturity when the fruit or vegetable is not susceptible to fruit fly attack. This transition from feeding to wandering occurred when the larva attained a critical nutritional or developmental status. Being facultative breeders and having a short life cycle, fruit flies are multivoltine in nature having more than one generation per year. To achieve successful eradication, a sufficient dose of lure-toxicant was necessary. By feeding on the host plants, the flies attain sexual maturity within 10-20 days and mate together to start a new cycle of damage. Mean number of marketable fruits per tree, All figure content in this area was uploaded by Baljit Singh, Eco-friendly Management of Fruit Flies, Bactrocera spp. Because eradication was achieved, quarantine regulation and preventive control should be implemented to prevent infiltration and reestablishment of the fly from adjacent, infested islands. Irsad and Parvez Qamar RizviDepartment of Plant ProtectionFaculty of Agricultural Sciences A.M.U., Aligarhmohdirshad060@gmail.com.

Issuing the multiple crop yield forecast for rice, wheat and mustard in state at early season (F1), mid season (F2) and pre-harvest season (F3). Daily. Fruit fly is the most serious pest of different horticultural crops among the world & it is also the most destructive pest. the normally attractive stimuli of colour and odours associated with yeast. This technique has been successfully used for the eradication and control of several Bactrocera species [8], Annual population incidence of Oriental fruit fly (Dacus dorsalis) Hendel in a fruit orchard at Peshawar, Pakistan. Again, it is also established that before developing insect pest management programme for a specific agro-ecosystem, it is necessary to have basic information on the incidence of the pest in relation to weather parameters which help in determining appropriate ABSTRACT In India, fruit flies have been identified as one of the ten most serious problems of agriculture because of their polyphagous nature and the huge economic loss it causes to the fruits and vegetables (2.5 to 100%). Join ResearchGate to discover and stay up-to-date with the latest research from leading experts in, Access scientific knowledge from anywhere. Guava fruit flesh volatiles were analyzed by GC-MS, and the differences of amount of responded oriental fruit fly adults and eggs laid by oriental fruit fly effected by guava fruit flesh volatiles and other lures. A total of 49313 males were captured (14 to 50 SMW) in the four crops by different coloured PAU fruit fly traps. 25.7 per cent fruits were found infested in the orchards fixed with fruit fly traps (treated orchards) as compared to 81.3 per cent in control plots. Quarantine restrictions imposed by importing countries to avoid entry and establishment of the fruit fly. Gibberellic acid treatment of fruits given prior to 'colour break' enhanced the resistance of fruits against oviposition and fly development (Mohamed Jalaluddin, 1996). The mean percentage of fruit fly damage was also lowest in triangular traps in peach (4.33%) and in pear (6.72%) respectively. B. dorsalis can complete 3-5 generations per year. Management of fruit flies in fruit crops. Per cent fruit damage was lowest in traps with 3 holes. Among the fruit fly complex in Pakistan Dacus zonatus (Saunders) and D. dorsalis Hendel are serious pests of guava and mango (Ghouri, 1960). Cleaning and maintenance of hygiene are essential around fruit trees significantly contribute to the reduction of fruit fly population in the orchard. Highest males were captured in Kinnow followed by guava, pear and peach. Chemical control is widely used among farmers. Statistical analysis found no interaction between farm-level and village-level control when both were used, which suggests that individual farmers still have an incentive to apply farm-level controls, whether or not their neighbours are doing so, and thus to participate in cooperative control without reference to participation by neighbours. Agricultural Research Institute for production of Mostly the chemical control measures are practiced for the management of fruit flies in Pakistan in general and particularly in Khyber Pakhtunkhwa. If you grow backyard fruit trees, unfortunately you’ll find there’s a range of pests wanting to get to your harvests before you do.And one of the most insidious is the Queensland fruit fly (which despite its name, is active well beyond Queensland). 1. To control fruit fly species, different management tools such as cultural practices, mechanical, biological, chemical, and physical control, have been implemented. The adults are small yellow-brown flies 1½ to 2 times larger than a house fly, with rather long, patterned wings (Figure 1A and B). is most important insect-pests of guava and the crop is highly prone to damage by this pest in Punjab. The egg is creamy white, spindle-shaped and measuring about 1 mm in length. 2. Mass Trapping of Fruit Flies Using Methyl Eugenol Based Traps, Impact of abiotic factors on population dynamics of Bactrocera dorsalis Hendel and Bactrocera zonata (Saunders) at different ecological zones in NW Plains of India, MODIFICATION IN PAU FRUIT FLY TRAP FOR MANAGEMENT OF Bactrocera spp. Out of these, B. dorsalis was attracted towards methyl eugenol followed by B. zonata. Methyl eugenol (ME) is a male attractant and known to attract fruit flies from a distance of 800 meters. Methyl eugenol, when used together with an insecticide (malathion, fipronil or naled) impregnated into a suitable substrate, forms the basis of male annihilation technique (MAT) and results in the reduction of male population of fruit flies to such a level that eradication and suppression is achieved (Vargas et al., 2010a). Pupal cold storage did not pose negative impacts on the mating competition and response to methyl eugenol (ME) in the males. B. Cucurbitae was attracted to the cue lure in guava orchards. Eggs are laid singly and hatch in about 2–3 days. Maximum number of marketable fruits in these orchards was recorded in orchard of village Talanian (1243 fruits/tree) followed by orchard of village Rasulpura (1203 fruits/tree) in the treated orchards as compared to 721 and 603 in untreated plots, respectively.
