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. It completes 5-10 generations in a year in tropical areas and less than 4 in subtropical areas. Entomology Reporter 1: 8-9. However, cost: benefit ratio was quite low in triangular traps (1:28.20) as compared to cylindrical traps (1:68.10), spherical traps (1:82.95) and PAU fruit fly traps (1.92.00). Join our WhatsApp group and get the most important updates you need. The results revealed that triangular traps (111.17 males/trap/week) had captured significantly more population followed by PAU fruit fly traps (67.39 males) followed by cylindrical traps (65.44 males) followed by spherical traps (50.28 males). 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). Among the fruit fly complex in Pakistan Dacus zonatus (Saunders) and D. dorsalis Hendel are serious pests of guava and mango (Ghouri, 1960). About 67 per cent fruit growers were found to be more sincere in adopting this technology. Abstracts, International Conference on 30 families in tropical and subtropical regions of the world, including guava, mango, cherry, jujube, citrus, and chilli . Upon completion of larval feeding, the third instar larvae burrow into the soil and pupate inside a puparium at a depth of 6 cm. USE CHEMICAL INSECTICIDE: Spray Trizaphos 40% EC @ 1 ml/ liter of water. Adults generally mate at dusk. More the number of males captured, less were the maggots/fruit and the fruits in 16 traps/ acre had significantly less number of maggots. Eggs are laid singly and hatch in about 2–3 days. Agricultural Research Institute for production of fruit orchard at Peshawar, Pakistan. 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. This leads to poor commercialization in domestic markets and quarantine restrictions from importing countries. The Caribbean fruit fly, Anastrepha suspensa (Loew), is also called the Caribfly and guava fruit fly. Leave a Comment / Pest, Plant Protection / By arhorticulture / () ... Use Methyl eugenollure traps @ 25nos/ha to monitor and kill adults of fruit fly. 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. Guava fruit flies, Bactrocera spp. Chughtai and Baloch (1988) reported that Carbicron and Dipterex gave significantly better control of melon fruit fly larvae under D.I. Management of fruit flies in fruit crops. Protein hydrolysate was identified as an efficient attractant for female fruit flies. Among insect pest, the fruit fly is the major limiting factor in obtaining a good quality of fruits and vegetable and known to cause considerable losses. 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%). Biological. Singh P 1996. Only species of the Strumeta group of subgenera were attracted to methyl eugenol. The management of fruit flies is challenging because third-instar larvae leave decaying fruits and drop to the ground to pupate in the soil; consequently, both larvae and pupae in fruits and soils are just like shelter that prevents reach of applied insecticides against target stages of a fruit fly. The most widely used technique of this kind is male annihilation technique (MAT) where methyl eugenol, a para-pheromone is used together with an insecticide impregnated into a suitable substrate. The results revealed that 16 traps/acre had significantly more population of captured males of Bactrocera dorsalis (Hendel) and B. zonata (Saunders) compared to 4, 8 and 12 traps/acre. 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. No species was attracted to both types of attractants. Ludhiana (December). It is recorded, that crop losses caused by fruit fly ranging from 20-80 percent usually depend upon the crop locality, season and variety. 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. 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. Chemical control is widely used among farmers. This technique has been successfully used for the eradication and control of several Bactrocera species (Cunningham 1989, Singh 2012, Singh and Sharma 2013, ... Mann (1980) reported the seasonal history and occurrence of B. dorsalis on different fruit crops in Punjab. Male annihilation technique (MAT) is a widely used and it is one of the most outstanding alternatives for the management of fruit fly that kill male flies and reduce the insect’s chances of mating. In addition, compared with the adults that were subjected to the same pupal storage protocol (five-day-old pupae stored at 13 °C), adult exposure to 41 °C for 1 h showed significant reparative effects on fecundity. Pupal cold storage did not pose negative impacts on the mating competition and response to methyl eugenol (ME) in the males. Five fruit fly species viz., Bactrocera dorsalis, Bactrocera zonata, Bactrocera correcta, Bactrocera verbascifoliae and Bactrocera Cucurbitae were trapped. ment practices and land factors for crop yield forecasting in pear with Methyl Eugenol based Traps at different locations in P, Eco-friendly Management of Fruit Flies, Bactrocera spp. Out of these, B. dorsalis was attracted towards methyl eugenol followed by B. zonata. In China, it causes extensive damage to mango and guava production [6,7]. Different shaped methyl eugenol based traps were evaluated against Oriental fruit fly, Bactrocera dorsalis (Hendel) and peach fruit fly, Bactrocera zonata (Saunders) in guava orchard from 30 th SMW to 38 th SMW during 2014-15. The fruit damage rates of guava in research base were only 6.67%-7.33% during the peak period of oriental fruit fly in June 2008, while they were 90.53%-98.00% in control area, obtaining good control effect against the pest. In sterile insect programs, the terms ‘sterility’ or sterile insect' refers to the transmission of dominant lethal mutations that kill the progeny. Because of the difficulties associated with the control of this pest through chemical insecticides, the farmers experience huge losses to guava crop. To develop a regression model, Specimens of Dacini were collected in traps containing male attractants in north-east Australia and 26 islands of the South Pacific area. Result of chemical constituents analysis indicated that 18 kinds of components were detected. Know What WHO Says. Harvest guavas before they ripen fully. It is very much difficult to manage the pest simply through the application of chemical pesticides due to their peculiar biological features. The study on different shapes of traps revealed that triangular traps had significantly high population of male fruit flies as compared to cylindrical traps, spherical traps and PAU fruit fly traps in different fruit crops. Subscribe to our Newsletter. The United States Department of Agriculture's Agricultural Research Service initiated an area-wide fruit fly management program in Hawaii in 2000. 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). It is an excellent source of pectin, phosphorus, calcium, iron, potassium, and sodium with a pleasant aroma. 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. Species composition of fruit flies, Bactrocera spp. A female can lay 10–30 eggs during each oviposition and can lay more than 1200 eggs during its lifespan. Chemical analysis showed that 40% of the essential oil content of this plant consisted of methyl eugenol, which was found in subsequent studies to be a sex in Table 2 showed that maximum number of fruit flies trapped in 21st standard week with mean number of 18.33 in leaf extracts of basil.
