This happens if there are sufficiently deep cracks on their skin. When the larva reaches a size of about 1 cm, it pupates. moving up to 200 km. Since the pupae “mature” in the soil, weeding and loosening of the soil should be carried out regularly in order to remove the pupae to the surface, where they will be destroyed by birds or other insects. 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. There are total larval periods was 5.9±0.979 and 5.19 ± 0.245 days while, pupal period was 7.3 ± 0.23 and 7.03 ± 0.245 days during both the years in the month of June and July. Dacus cucurbitae Coquillett -- Tephritidae (Contacts)GO TO ALL: Bio-Control Cases Native to the Indo-Malayan region, the melon fly was first recorded in Hawaii in 1897. The female lays eggs under the skin of the fruit of the host plant. It disperses northward annually, usually arriving in northern Florida in June and other southeastern states in July, where no more than three generations normally occur before cold weather kills the host plants. It is distributed in Turkey, Azerbaijan, Armenia, Georgia, Kazakhstan, Turkmenistan, and Kyrgyzstan. A slightly pronounced taper is noticeable: to the posterior end, the larva can be significantly expanded. Leaving the shell, they go deep into the fetus and begin to actively eat. Males do not have such sharp “teeth” on the proboscis to make holes, but they are able to find holes made by females and drink juice from them with the help of their long proboscis. The spring years coincide with the formation of fruits in the spring. This species of flies is extremely fertile. Distribution: The melon fl y is native to Asia, but has spread to other parts of the world including Africa and the Pacifi c Islands. The significant differences were observed in the life cycle of the pest when reared on bitter gourd, bottle gourd and watermelon. 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. The head and body of the insect have slightly different shades. Pilot project implementation sites in Mekong region. During the severe winter months, they hide and huddle together under dried leaves of bushes and trees. And after 2-4 days they hatch into larvae (maggots) and start to feed on the fruit flesh. The first spring years of the melon fly coincides with the formation of the first fruits, although the females are capable of reproduction already on the 10th day of their life. 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. Melon fly has been recovered on several occasions in California, and although it has not become established in the western hemisphere, the tropical and subtropical regions would be suitable habitat. Usually one egg is laid in one fruit. In addition to traditional melons, watermelons and pumpkins, this pest can threaten about a hundred other plants. 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. Young or newly formed fruits, whose skin is still not dense, are especially vulnerable to flies. I have written briefly about this subject in another article but since then, I have been bombarded with additional questions and requests for more pictures so I decided to dedicate an entire article to this subject. First things first, let’s learn about its life cycle. The main pests are melon fly larvae. It is distributed throughout the Middle East and western Asia from Israel to India. LIFE CYCLE Development period from egg to adult ranges from 12 to 28 days. Mostly, these are climatic zones of subtropics and mild temperate climate. Oviposition response of melon fruit fly, Bactrocera cucurbitae (Coquillett) to different phenolic compounds Sharma, R. and Sohal, S. K. ABSTRACT The oviposition deterrent effects of four phenolic compounds (quercetin, rutin, gallic acid and tannic acid) were investigated against the melon fruit fly, Bactrocera cucurbitae. Laboratory studies were conducted to study the comparative biology of fruit fly, Bactrocera cucurbitae in different cucurbitaceous crops viz. Apparently t… However, the melon fly was unable to complete its life cycle successfully on chayote showing that factors inhibiting larval development in melon fly could be attributed to biochemical constituents. They are major pests of beans, bittermelon, winter melon, cucumbers, eggplant, green beans, hyotan, luffa, melons, peppers, pumpkins, squashes, togan, tomatoes, watermelon, and zucchini. Further, it is recommended to repeat the treatment after 2 weeks. An earlier planting is also recommended so that the fruits have time to form and “grow” with thick skin before the first summer of melon flies. BIOLOGY. The life expectancy of adults is about two months. The body of the fly is covered with dense hairs of small length. In addition, the use of insecticides such as Decis or Arrivo is recommended as a preventive measure. The female may lay as many as 1,000 eggs. EGGS. Melon fly is a serious pest of most gourds. It is present throughout the year in southern Florida, where it is limited mostly by availability of host plants. Quarantine laws aimed at preventing the entry and establishment of melon flies in areas where it does not occur often reduces the export potential of locally grown crops. Development from egg to adult under summer conditions requires about 16 days. The Baluchistan Melon Fly (Myiopardalis pardalina) is a major pest of melons and other cucurbits. Prior to its invasion, cucurbit crops were widely grown for local consumption and some were exported to California. Life Cycle The melon fruit fly remains active throughout the Egg:Melonworm moths deposit oval, flattened eggs in small clusters, often averaging two to six overlapping eggs per egg mass. The appearance of flies on the territory of Ukraine, Moldova, southern Russia. When using these drugs, you must strictly follow the instructions. As a rule, a plant loses much more fluid from various mechanical damages. The maggots will then metamorphosis to pupae. Fruit fly Management TYPICAL LIFE CYCLE Fusarium wilt distances within a short time; exceptional observa-tions showed a Bactrocera sp. Fruit fly development (life cycle) depends on temperature. The larva eats melon juice and any kind of fetal tissue: pulp, fiber or seeds. They damage the fetus from the inside (eating the pulp and seeds), making it unfit for consumption, inhibit the formation of seeds. Throughout the distribution area, it is struggling with variable success, and a person does not always triumph in it. The insect has a wide distribution range. In some cases, backfilling of melons helps with deterrents - ash, tobacco dust and others. Larvae emerge from the eggs within 48 hours. The female fly lays its eggs under the skin of the watermelon. Melon flies use at least 125 host plants. For these purposes, Zenith means (in concentrations of 0.25 liters per 10 liters of water) or Rapira (2 liters of solution per 1 ha) are used. Outside of malathion protein bait sprays and GF-120 NF Naturalyte Fruit Fly Bait, little information is available on other insecticides. The first spring years of the melon fly coincides with the formation of the first fruits, although the females are capable of reproduction already on the 10th day of their life. An effective remedy is the planting of frightening plants near the melon - castor oil plants or calendula. During this time, one female is able to lay more than a hundred eggs. common name: melon fly scientific name: Bactrocera cucurbitae (Coquillett) (Insecta: Diptera: Tephritidae) Introduction - Synonyms - Distribution - Description - Life History - Damage - Hosts - Management - Selected References Introduction (Back to Top). The first signs of infection with fruit parasites is the appearance of many small spots or tubercles on them, which are formed in places where females bite the skin. Pupation occurs in the soil. Here she "terrorizes" the agriculture of India and Pakistan. Eggs of the Baluchistan melon fly (BMF) are able to survive harsh winter conditions. The maggots (larvae) are creamy-white, legless and attain a length of 10 mm. The lifespan of an adult fly varies depending on many factors, and can be as long as 5–15 months. The life cycle from egg to adult requires 14-27 days. Insect larvae have the usual shape for flies. bitter gourd, bottle gourd and watermelon. Studies on culture of melon fly indicated the absence of plant traits resisting oviposition on chayote fruit. This is a medium-sized fly, mainly fawn yellow, less often brownish. There are total larval periods was 5.9±0.979 and 5.19 ± 0.245 days while, pupal period was 7. It has a 30 day life cycle when conditions are optimal. In Hawaii, it has caused serious damaged to melon, cucumber and tomato crops. In Asia, it is recorded from Bangladesh, Bhutan, Brunei, Cambodia, China, Hong Kong, India, The invasion of melon flies is a serious threat to the cultivation of any pumpkin culture. 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. Insect prophylaxis is standard. Melon Fly Bactrocera cucurbitae be extruded. It is rare when the pupae of this pest are more than 8 mm. On them four transverse stripes of yellow color are visible. Their body is cylindrical. Usually the color of the head is brighter. The duration of total life cycle was 15.5 ± 1.952 and 13.66 ± 2.482 days during 2002 and 2003 in June and July. The body length of the insect is about 0.6-0.7 cm, the wingspan is about 0.5 cm. The spots and tubercles have a characteristic brown hue. The life cycle of a leaf miner has the following stages: egg, three larval instars, a pupal instar and the adult fly. The combination of proper melon farming techniques using chemicals is the only effective method for successfully combating this pest. An insignificant amount of the vital products of the larvae, as well as the flesh damaged by them, cause mild diarrhea.
