Estimation of Yield Loss of Jatropha curcas L. Due to Calidea spp. (Heteroptera: Scutelleridae), in the Sub-Sudanian Zone of Burkina Faso
- Wakaï Younous Djimmy; Souleymane Nacro
- Jatropha curcas L. is a biofuel plant that belongs to the Euphorbiaceae family. The production of this plant can improve the livelihood of smallholder farmers in rural areas. Meanwhile, several insect pests including Calidea spp. feed on J. curcas L. Calidea spp. is a Heteropteran that feeds on the flowers and the fruit of J. curcas. No yield loss assessment of J. curcas due to this pest has been conducted. Therefore, the objective of this study was to assess the yield loss associated with this insect pest. This study was conducted in Léo, South Burkina Faso during the 2013 rainy season, from August to October. A randomized complete bloc design was used. The experimental design consisted of 5 treatments and 5 replicates. The treatments consisted of various numbers of adults of Calidea spp. caged with a 4-year old single J. curcas plant:T0 (control = no insect pest), T1 (4 couples) T2 (8 couples), T3 (16 couples) and T4 (20 couples). The monitored variables included the number and weight of fruit, the number and weight of undamaged and damaged seeds and the damage due to the insect pest. The results showed that the control (T0) and T1 (10.5% damage) showed the lowest damage while T3 and T4 (36.83%) were the most damaged. There was 7% yield gain in T1 while there was 59% yield loss in T4.
