During the severe winter months, they hide and huddle together under dried leaves of bushes and trees. 2005). It has been given the nickname, ‘trash fly’. Maggots have been found in over 125 kinds of fruit and vegetables in Hawaii alone. Life Cycle: A female melon fl y usually lays eggs under the skin of host fruit; however, in its favored hosts in the family Cucurbitaceae, eggs may also be laid into fl owers, stems, and exposed roots. Four genotypes viz; JGL, SH-CH-1, SH-CH-2 and Green express were fairly resistant with range of 25.8-37.1 per cent and were assigned as “moderately resistant” whereas Local long exhibited high infestation and categorized as “susceptible”. 3) Decomposition of plant tissue by invading secondary microorganisms The life cycle from egg to adult requires 14-27 days. Oriental fruit fly has been established in Hawaii since 1946 where it is a major pest of agriculture, particularly on mangoes, avocados and papayas. After several molting processes, they drop from the fruit and burrow into the soil to pupate. The melon fruit fly remains active throughout the year on one or the other host. Adults are active throughout the year in climates where temperatures exceed about 15oC. •Spray 50 ml of malathion 50EC + 0.5 kg of gur/suger in 50 l. of water/ha when serious attack. •Maggots : lrgless and headleas,dirty white wriggling creatures. •The maggots pollute and destroy fruit by feeding on pulp. These bacterial colonies are more plentiful under humid conditions. The number of eggs found at any time in the reproductive organs is no indication of the total number of eggs an individual female is capable of depo… Melon fly may also lay eggs in flower buds and stems. Life Cycle Fruit Fly. The present studies entitled “Biology and management of melon fruit fly, Bactrocera cucurbitae on cucumber” were carried out at Central Institute of Temperate Horticulture (CITH), Srinagar and Division of Entomology, SKUAST-Kashmir, Shalimar, Srinagar during the two consecutive years 2012-13. After introduction, it can easily disperse due to its high reproductive potential, high biotic potential (short life cycle of 3-5 weeks, up to 10 generations of offspring per year), and a rapid dispersal ability. Note that at this stage of the life cycle you are unlikely to be able to recognise the presence of fruit fly eggs in your fruit as the eggs are very small. The eggs hatch into larvae inside the fruit after a few days (2-4 days). 2) Feeding by the larvae. Longevity of melon fly adults was enhanced to 30-52 days for males and 30-60 days for females when fed with water, molasses and honey as well as on water, molasses and proteinex. The lower developmental threshold for melon fruit fly was recorded as 8.1° C (Keck, 1951). Melon is annual plant, which means that it finishes its life cycle in one year. The female adult fly lays eggs (1-20) into the maturing and ripening fruit of the host plant. ... debris, faeces, dead animal bodies, and even other insects, dead or alive. Life cycle Damage •The maggots pollute and destroy fruit by feeding on pulp. Several biotic factors limit the production and productivity of cucurbits, of which the cucurbit fruit fly, Bactrocera cu-curbitae (Coquillett) (Diptera: Tephritidae), has been the most prominent pest. Symptoms & Life Cycle. Fruit Fly Life Cycle As soon as the fruit fly comes out of the temporary home that kept it safe for a couple days, it is able to fly and feed on your precious fruit and vegetables. Biology: The life cycle and biology of peach fruit fly are generally similar to those of its tropical relatives. Life cycle Melon flies are active throughout the year. Female flies need protein to develop eggs. •Only the maggots cause damage by feeding on near ripe fruits. During the severe winter months, they hide and huddle together under dried leaves of bushes and trees. The full grown maggot was very mobile and measured 9.62±0.87 and 2.05±0.32 mm in length and breadth. Lack of access to water led to sudden death of the flies. Daily hoeing caused maximum pupal mortality (87.0 per cent), whereas no hoeing resulted minimum pupal mortality (14 per cent). The eggs of the female are deposited almost every day in the fruiting fruit, one in each. Microscopic footage showing fruit fly anatomy and its life-cycle. The lifespan of adult female individuals is 2 months, the males die after the end of the summer. Results clearly indicated that traps once charged with plywood, straw board, and acacia blocks impregnated with cue-lure or methyl eugenol can be run effectively for longer periods in attracting B. cucurbitae and B. dorsalis. Eggs are laid in fruit, and maggots cause the fruits to rot. moving up to 200 km. •Damage caused serious in melon and after the first shower of the momsoon. The experiments under laboratory conditions revealed that B. cucurbitae completed three full generations per year, in addition to the 4th generation which extended only upto pupal stage only, and overwintered until emergence of adults in next year. The life cycle takes about 2.5 weeks during summer. The average length and breadth (with expanded wings) of male was 8.74±0.32 and 11.46±1.16 mm, whereas, the female measured on an average 9.94±0.20 and 15.92±0.74 mm in length and breadth (with expanded wings). The melon fly puparium was found to be barrel shaped, eleven segmented and measured on an average 5.72±0.13 and 2.46±0.11 mm in length and breadth. Life Cycle. The mature larva emerges from the fruit, drops to the ground, and forms a tan to dark brown puparium. About nine days are required for attainment of sexual maturity after the male adult fly emerges. The pupal stage lasts about 10 days. 2004). Pepper fruit fly; it is also known as the tomato fruit fly. Morphometric measurements of life stages of B. cucurbitae revealed that freshly laid eggs were glistening white, slightly curved, elongated and tapering at one end while rounded at the other end. The mean Pre-oviposition period13.5±1.5 and oviposition period 18.0±6 days while, mean mating period (3±1hrs), fecundity 80.0±20 eggs/life cycle and incubation period of eggs varied from 1.25±0.25 days was observed of cucurbit fruit fly. click here.. Download Pdf During the hot and dry season, the flies take shelter under humid and shady places and feed on honeydew of aphids infesting the fruit trees. Maggots hatch from the eggs and tunnel through the fruit, feeding on the pulp. During the hot and dry season, the flies take shelter under humid and shady places and feed on honeydew of aphids infesting the fruit trees. Illegal movement of fruit is a major risk for invasion of fruit flies elsewhere. Melon is a member of the Cucurbitaceae family. The lower and upper developmental thresholds for eggs were 11.4 and 36.4° C (Messenger and Flitters, … Bulletin de la Societe Entomologique d'Egypte, 54:231-241. Studies on biology of melon fruit fly, B. cucurbitae (Coquillett) revealed that the average duration of incubation, maggot, prepupal and pupal period varied between 16.8±6.19 hours, 4.5±1.13, 0.8±0.25 and 8.4±0.51 days, respectively. After they become widely spread and popular in Europe, melons were introduced to America by the Spanish settlers during the 15th and 16th century. During the severe winter months, they hide and huddle together under dried leaves of bushes and trees. The fly life cycle starts from the egg, to the larva, pupa and finally the adult. Mature attacked fruits develop a water soaked appearance. The lowest number of maggots per fruit was observed in NSKE (0.5%) (4.5±0.86) as compared to untreated check (46.2±6.90), Sher-e-Kashmir University of Agricultural Sciences and Technology, Kashmir, http://krishikosh.egranth.ac.in/handle/1/92187, Maintained and  © Copyright 2017 ICAR-IARI, New Delhi . •Other cucurbitaceous infested up to 50 %. Impact. Sex ratio in B. cucurbitae was recorded as 0.95:1.25 (Male:Female). Bio-decomposer technique will curb stubble burning pollution, NSCL Management Trainee (Production) Solved Paper 2019. Agriculture Objective Questions for NSC, IFFCO, ICAR, BHU, etc. •Host plant : musk melon and other cucurbits & also found tomato, chillis, guava, citrus, pear, fig, cauliflower etc. Effect of cultural practices on pupal mortality of B. cucurbitae revealed maximum mortality (87.0 per cent) in clay soil, whereas minimum (17 per cent) in orchard soil. •Other cucurbitaceous infested up to 50 % . bitter gourd, bottle gourd and watermelon. Eggs are laid in flowers and fruit, or succulent plant stems or roots In fruit, the punctures or stings in the skin can also deposit fruit decaying bacteria in … The first and second instar maggot measured on an average 1.49±0.28 and 6.40±0.86 mm in length and 0.31±0.07 and 1.21±0.09 mm in breadth, respectively. It can be found throughout most of southern Asia, several countries in Africa, some island groups in the Pacific. Melon Fly Life Cycle The mean incubation period varied from 1.7±0.12 days in 2002 and 1.4±0.16 days in 2003 at temperature range from 31.9 – 32.2°C in 2002 and 27.3 – 30.8°C while, relative humidity was 56.7 – 62.8% during 2002 and 60.6–81.2% during 2003. Development time, longevity and reproduction rate are all variable depending on temperature, feeding resources and host plant availability. Fruit fly Management TYPICAL LIFE CYCLE Fusarium wilt distances within a short time; exceptional observa-tions showed a Bactrocera sp. Papayas grown in Hawaii are infested with four species of fruit flies: the Oriental fruit fly (Dacus dorsalis), the Mediterranean fruit fly (Ceratitis capitata), the melon fly (Dacus cucurbitae), and the Malaysian fruit fly (Bactrocera latifrons). The length of time required for the medfly to complete its life cycle under typical Florida summer weather conditions, and on which eradication schedules in Florida are based, is 21 to 30 days. Larval feeding damage in fruits is the most damaging. Life Cycle The melon fruit fly remains active throughout the year on one or the other host. Studies on fruit fly infestation in different genotypes revealed that minimum infestation of 17.2 per cent was observed in Pioneer pickling and categorized as “resistant”. Avoids large fruit, where the peel becomes dense. The damage to crops caused by melon flies result from 1) oviposition in fruit and soft tissues of vegetative parts of hosts 2) feeding by the larvae, and 3) decomposition of plant tissue by invading secondary microorganisms. Melon Fruit Fly; Scientific Name: Bactrocera cucurbitae (Coquillet) Order and Family: Diptera, Tephritidae; Lure: Cuelure ; Description. The data on per cent fruit damage (number and weight basis) revealed that Neem Seed Kernel Extract (NSKE) @ 0.5% was significantly superior over attractant and control in reducing the per cent fruit infestation by B. cucurbitae. Eggs can also be laid into flowers, stems as well as exposed roots. Its closest relatives are squashes and cucumbers. A major route by which this pest may spread in trade or transport is through eggs and larvae hidden in fruiting bodies. Life Cycle of the Fruit Fly. The fruit fly's life cycle begins when the female lays her eggs on a piece of fermenting fruit or other decaying, sweet organic material.
