Using two-sex life tables to determine fitness parameters of fourBactroceraspecies (Diptera: Tephritidae) reared on a semi-artificial diet

Abstract

Fruit flies in the genus Bactrocera are global, economically important pests of agricultural food crops. However, basic life history information about these pests, which is vital for designing more effective control methods, is currently lacking. Artificial diets can be used as a suitable replacement for natural host plants for rearing fruit flies under laboratory conditions, and this study reports on the two-sex life-table parameters of four Bactrocera species (Bactrocera correcta, Bactrocera dorsalis, Bactrocera cucurbitae, and Bactrocera tau) reared on a semi-artificial diet comprising corn flour, banana, sodium benzoate, yeast, sucrose, winding paper, hydrochloric acid and water. The results indicated that the larval development period of B. correcta (6.81 ± 0.65 days) was significantly longer than those of the other species. The fecundity of B. dorsalis (593.60 eggs female-1) was highest among the four species. There were no differences in intrinsic rate of increase (r) and finite rate of increase (λ) among the four species. The gross reproductive rate (GRR) and net reproductive rate (R0) of B. dorsalis were higher than those of the other species, and the mean generation time (T) of B. cucurbitae (42.08 ± 1.21 h) was longer than that of the other species. We conclude that the semi-artificial diet was most suitable for rearing B. dorsalis, due to its shorter development time and higher fecundity. These results will be useful for future studies of fruit fly management.

Effects of three different cultivars of cruciferous plants on the age‐stage, two‐sex life table traits of Plutella xylostella (L.) (Lepidoptera: Plutellidae)

“…The body weight of immature and mature stages of P. xylostella was measured using an electronic weighing balance (Model # SE391, Scientech, USA) accordingly by Jaleel et al ().…”

Evaluating the repellent effect of four botanicals against two Bactrocera species on mangoes

“…The population of both species (B. dorsalis and B. correcta) was reared in the controlled room (25 ± 2 C, 60 ± 5% relative humidity, and a photoperiod of L:D 14:10 h) at the South China Agricultural University, Guangzhou, China. The temperature was controlled by the air-conditioner (Gree Electric Appliances, Inc. of Zhuhai, Zhuhai, China) and the humidity was maintained by a humidifier (Jaleel et al, 2018a(Jaleel et al, , 2018b. Adult flies were reared in cages (30 × 30 × 30 cm) by providing water-soaked cotton wool in a box (12 × 6.8 × 7 cm), powdered yeast and sugar (2:1) in a petri-dish (6 × 1.5 cm).…”

A Novel Solid Artificial Diet for Zeugodacus cucurbitae (Diptera: Tephritidae) Larvae With Fitness Parameters Assessed by Two-Sex Life Table

“…Natural food may contain harmful materials, such as insecticides and pathogens, therefore influencing precision and accuracy of research results. While various artificial diets have been successfully developed for rearing economically important fruit fly pests, for example, Bactrocera dorsalis ( Jayanthi and Verghese 2002 , Liu et al 2015 ), Bactrocera zonata ( Rabab et al 2016 ), and Mediterranean fruit fly ( Tanaka et al 1969 , Vargas and Carey 1989 ), only a few artificial diets have been examined or developed for Z. cucurbitae ( Tanaka et al 1969 , Chang et al 2004 , Huang and Chi 2012 , Jaleel et al 2018 ).…”
