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. During the severe winter months, they hide and huddle together under dried leaves of bushes and trees. Life Cycle The melon fruit fly remains active throughout the year on one or the other host. Yellow and green coloured traps attracted significantly high number of B. cucurbitae in cucumber. Fruit fly Management TYPICAL LIFE CYCLE Fusarium wilt distances within a short time; exceptional observa-tions showed a Bactrocera sp. Pupation occurs in the soil. Larval feeding damage in fruits is the most damaging. Adults are active throughout the year in climates where temperatures exceed about 15oC. It can be found throughout most of southern Asia, several countries in Africa, some island groups in the Pacific. 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 adult flies congregate on foliage and fruit to feed on bacterial colonies and later to mate.

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. moving up to 200 km. Development from egg to adult under summer conditions requires about 16 days. 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. Mature attacked fruits develop a water soaked appearance. Life Cycle of the Fruit Fly. The melon fruit fly remains active throughout the year on one or the other host. 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. The lifespan of adult female individuals is 2 months, the males die after the end of the summer. 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. Microscopic footage showing fruit fly anatomy and its life-cycle. 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. Development time, longevity and reproduction rate are all variable depending on temperature, feeding resources and host plant availability. Melon is annual plant, which means that it finishes its life cycle in one year. These bacterial colonies are more plentiful under humid conditions. Melon is a member of the Cucurbitaceae family. •Only the maggots cause damage by feeding on near ripe fruits. Pre-oviposition and oviposition period ranged between 10-15 and 12-28 days during July to August respectively. 2) Feeding by the larvae. Sex ratio in B. cucurbitae was recorded as 0.95:1.25 (Male:Female). The life cycle takes about 2.5 weeks during summer. •Damage caused serious in melon and after the first shower of the momsoon. ... debris, faeces, dead animal bodies, and even other insects, dead or alive. Daily hoeing caused maximum pupal mortality (87.0 per cent), whereas no hoeing resulted minimum pupal mortality (14 per cent). About nine days are required for attainment of sexual maturity after the male adult fly emerges. The fly life cycle starts from the egg, to the larva, pupa and finally the adult. 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. Life cycle Melon flies are active throughout the year. The larval stage of the life cycle is the most damaging to fruits because of larval feeding on the soft flesh of fruits. Understanding the fruit fly lifecycle provides many clues as to the best way to manage these damaging pests Fruit flies are important pests of fruits, vege-tables, and other ornamental plants (Bharathi et al. Life Cycle The female lays eggs under the skin of the fruit of the host plant. The eggs hatch into larvae inside the fruit after a few days (2-4 days). Female flies need protein to develop eggs. Agriculture Objective Questions for NSC, IFFCO, ICAR, BHU, etc. 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… 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. 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 .
