Drosophila suzukii Fruit flies are among the world’s most serious pests of different horticultural crops due … (2015) suggested that the presence of this fly in the tree canopy could be explained by attraction to green leaf volatiles, particularly β‐cyclocitral – a behavior that could favor the attack of fruits attached to the tree. The presence of Z. indianus on fallen damaged or rotting fruit is now common in the state of Veracruz. Mean numbers of males and females that emerged from fruit maturity treatments, force, and the brix value of the three fruit maturity stages were compared by one‐way ANOVA. Varietal and Developmental Susceptibility of Tart Cherry (Rosales: Rosaceae) to Drosophila suzukii (Diptera: Drosophilidae). A fruit juice extractor (Liquafruit, Taurus, Mexico) was used to extract guava juice for analysis. However, Anastrepha striatais an important pest in the American tropic… In this study, 74% of visually intact fruits collected from the tree canopy were found to be infested by D. suzukii. As guava fruits are available during September to November, this may be an important reservoir host for D. suzukii populations during the late fall and winter months which allow this insect to move onto blackberry fruits that subsequently appear in the spring. This underlines the likely importance of fruit volatiles in the localization of adult feeding and oviposition resources. Laboratory results indicated that this species was unable to oviposit and develop in guava fruits, even when punctured with an entomological pin. Tiny punctures that leak juice when the fruit is squeezed indicate infestation. Guava fruit fly hosts and damage These pests enjoy several host plants other than guava . Substrate-mediated feeding and egg-laying by spotted wing drosophila: waveform recognition and quantification via electropenetrography. For selection, a visual inspection of fruits was performed carefully by the same observer and with reference to a previously defined standard. Attraction to crushed fruit was also rank transformed (Conover & Iman, 1981) and compared by two‐way ANOVA. Two invasive pests, Drosophila suzukii (Matsumura) and the African fig fly, Zaprionus indianus Gupta (both Diptera: Drosophilidae), were recently found in traps used for monitoring tephritid pests (Anastrepha spp.) The larvae infest the fruit, rendering it unfit for human consumption. Holes were placed at 45 mm from the base. The agriculture experts have advised the farmers to adopt tunnel technology for growing off-season vegetables. 3 entomological pin (Elephant, Austria) (Lee et al., 2016). This probably is because it is not considered to be of primary economic importance, although it often is abundant and may be highly destructive to dooryard plantings of some tropical fruits. Common California crops that are threatened by guava fruit flies include black plum , cherry , citrus , peach , and melons . Guava fruit have a short shelf-life mainly due to rapid ripening rate and high susceptibility to decay, mechanical damage, and chilling injury. Non‐choice tests were performed because no other known hosts were fruiting during the period of the study in this region. Guava, Psidium guajava L. is the prime fruit of Indian Punjab in which two important fruit flies, Bactrocera dorsalis and Bactrocera zonata may destroy up to 100 per cent fruits of guava. Females of D. suzukii were capable of ovipositing in early ripe guavas in laboratory tests (23% of fruits were used for oviposition), although a high penetration force is required to pierce fruit (mean ± SEM = 89.0 ± 3.0 cN). Fruit fly is the most serious pest of different horticultural crops among the world & it is also the most destructive pest. It is important to note that guava fruits collected from trees were at least 3.5–5.5 m above the ground, much higher than the fruits of most cultivated berry crops. Learn more. Nature of damage: The male is attracted by the pheromone believing it is going to mate with the female. = 59, P = 0.68) or males (t = 0.217, d.f. The Caribbean fruit fly infests mostly mature to overripe fruits (Figure 5). LA Dinorín received an undergraduate scholarship from the Instituto de Ecología AC. = 2, P = 0.69; Table 1). The population of fruit flies fluctuates due to a succession of primary or alternate hosts, the environment complexity and abiotic factors (Montes et al., 2011). No differences were observed between ripe and overripe guava (Tukey test: P = 0.75), whereas yellow‐green stage fruit were significantly firmer than the other ripeness stages (Table 3). Peach Fruit Fly Bactrocera zonata (Saunders) The peach fruit fly is one of numerous fruit fly pests originating in south and southeast Asia that is highly polyphagous: able to infest many different kinds of fruits Guavas thrive in tropical areas, but their adaptability allows them to survive a few degrees of frost in Mediterranean climates. . Drosophila suzukii The application of 1-MCP can provide some improvement in storability. Fruit firmness, measured as surface penetration force, was evaluated using a randomly selected sample of 30 additional guavas at the same maturity stages. In Africa it attacks mango, papaya, guava and custard apple. The percentage of fruits that were infested and the number of adults of each sex that emerged were recorded.
