Host suitability indicates how closely or appropriately an insect colonized with its host for its safe life cycle, Abiotic factors momordica), and snake gourd (Trichosanthes anguina). 32(3): 10-11. June and July under room temperature in meerut condition. Present studies on biology of melon fruit fly, Bactrocera cucurbitae (Coquillett) revealed that the freshly laid eggs were glistening white, slightly curved, tapering at one end while rounded at the other end. The melon fruit fly, Bactrocera cucurbitae (Coquillett) (Diptera: Tephritidae) is distributed widely in temperate, tropical, and sub-tropical regions of the world. The mean generation times of B. cucurbitae ranged from 34 days reared on cucumber to 56 days reared on carrot medium. Biology and life cycle of bactrocera cucurbitae coquillett, a serious pest of cucurbits in jammu region (jammu and kashmir) india 1983; 45:406-413. B. cucurbitae has a wide range of host plants. Bactrocera became the main genus for the tribe after Bactrocera and Dacus were split, but Bactrocera was further divided into Zeugodacus and Bactrocera in 2015. The wide area management program involves the coordination of different characteristics of an insect eradication program (including local area options) over an entire area within a defensible perimeter, and subsequently protected against reinvasion by quarantine controls. Section 2 covers the life cycle of typical fruit flies, male lures (particularly methyl eugenol and Cuelure), protein baits, fruit fly damage and crop losses, and the host fruit preferences of the main fruit flies involved in the project. The oriental fruit fly, Bactrocera dorsalis (Hendel), is a very destructive pest of fruit in areas where it occurs. Section 2 covers the life cycle of typical fruit flies, male lures (particularly methyl eugenol and Cuelure), protein baits, fruit fly damage and crop losses, and the host fruit preferences of the main fruit flies involved in the project. For instance, one source lists the life cycle for B. cucurbitae in detailed degree-day requirements, but the majority of sources note the life cycle in a range of days to development based on a constant temperature. Approximately 48 hours after emerging from the puparia, female fruit flies are sexually mature and can begin breeding and laying eggs. Eggs are inserted into fruit in bunches of 1 to 37. 2012 incidence was peak (2.33adults/plant) It is prepared by the based on secondary data and literature review method. EGGS. B. cucurbitae is known to attack more than 125 plants including Bactrocera cucurbitae strains were selected for longer developmental period and larger body size on the basis of pre-oviposition period, female age at peak fecundity, numbers of eggs at peak fecundity, total fecundity, longevity of males and females, age at first mating, and number of life … complex (Bactrocera dorsalis and relatives) and the melon fly (Bactrocera cucurbitae). The first and second instars measured 1.49 ± 0.28 and 6.40 ± 0.86 mm in length, respectively, and 0.31 ± 0.07 and 1.21 ± 0.09 mm in breadth, respectively. This document is EENY199 (originally published as DPI Entomology Circulars 29 and 315), one of a series of the Departmento of Entomology and hosts, time, temperature and weather conditions. Using two-sex life tables to determine fitness parameters of four Bactrocera species (Diptera: Tephritidae) reared on a semi-artificial diet - Volume 108 Issue 6 In this area, the biology of this carpophagous insect was studied from the summer 2013 through 2015. The duration of egg incubation, and the larval, prepupal and pupal periods were 16.8 ± 4.9 hours, and 4.5 ± 1.13, 0.8 ± 0.25 and 8.4 ± 0.51 days, respectively. showed positive significant association Percentage fruit infestation and larval density/fruit were positively correlated with depth of ribs, flesh thickness, fruit diameter and fruit length, and negatively associated with fruit toughness. and 3.11 respectively) at third week of Mating Period and time of cucurbit fruit fly, Fecundity and viability of cucurbit fruit fly. Bionomics of fruit flies (Dacus spp.) The significant differences were observed in the life cycle of the pest when reared on bitter gourd, bottle gourd and watermelon. Female fruit flies can store sperm from multiple inseminations for use in future egg productions. common name: oriental fruit fly scientific name: Bactrocera dorsalis (Hendel) (Insecta: Diptera: Tephritidae) Introduction - Synonymy - Distribution - Description - Life History - Hosts and Damage - Quarantine and Management - Selected References Introduction (Back to Top).
