Temperature-dependent Development Model of the Striped Fruit Fly, Bactrocera scutellata (Hendel)(Diptera: Tephritidae)

Abstract

The striped fruit fly, Bactrocera scutellata, damages pumpkin and other cucurbitaceous plants. The developmental period of each stage was measured at seven constant temperatures (15, 18, 21, 24, 27, 30, and 33±1.0℃). The developmental time of eggs ranged from 4.2 days at 15℃ to 0.9 days at 33℃. The developmental period of larvae was 4.2 days at 15℃, and slowed in temperatures above 27℃. The developmental period of pupa was 21.5 days at 15℃ and 7.6 days at 33℃. The mortality of eggs was 17.1% at 15℃ and 22.9% at 33℃, Larval mortalities (1st, 2nd, 3rd) were 24.1, 27.3 and 18.2%, respectively, at 15℃, Pupal mortalities were 18.2% at 15℃ and 23.1% at 33℃. The relationship between developmental rate and temperature fit both a linear model and a nonlinear model. The lower threshold temperatures of eggs, larvae, and pupae were 12.5, 10.7, and 6.3℃, respectively, and threshold temperature of the total immature period was 8.5℃. The thermal constants required to complete the egg, larval, and pupal stages were 33.2, 118.3, and 181.2 DD, respectively. The distribution of each development stages was described by a 3-parameter Weibull function.

Insights on reproduction‐related genes in the striped fruit fly, Zeugodacus scutellata (Hendel) (Diptera: Tephritidae)

“…To prevent economic damage to crops, extensive control and eradication programs have been devised in various parts of the world (Vargas et al, 2015). The striped fruit fly Zeugodacus scutellata , is found in Korea, Thailand, India, China, Taiwan, and Japan (Guang‐qin et al, 1993; Jeon, Cho, et al, 2011; Shiraki, 1968). Larvae of Z. scutellata feed on the flowers and fruits of Cucurbitaceae plants (Ohno et al, 2006).…”

Complete mitochondrial genome of stripped fruit fly, Bactrocera (Zeugodacus) scutellata (Diptera: Tephritidae) from Anshun, Southwest China

“…The striped fruit fly, Bactrocera scutellata, is distributed in east and southeast Asia (Jeon et al 2011). The species is recognized from other Zeugodacus fruit fly with three postsutural yellow vittae by possession of a pair of medium-sized circular black spots across the face, 2 pairs of scutellar bristles, and the costal band slightly enlarged at the apex (Sugimoto et al 1988).…”
