“…causing serious damages of economic significance could attack this plant. These pests include 35 fungal species, 4 viral and 4 bacterial pathogens, 6 nematodes, and about 60 insect species (Anitha and Varaprasad, 2012). Thus, performing Jatropha breeding programs for pest and diseases resistance is of importance as well.…”

Aphthona whitfieldi Bryant (Coleoptera: Chrysomelidae) is a major insect pest of Jatropha curcas L. in Burkina Faso. This study aimed at evaluating the effect of the insect pest populations' density on the growth of the plant. To achieve this purpose, 90-day aged single plants were caged in a randomized complete block design experiment with 5 treatments and 5 replicates. The treatments consisted of increasing numbers of adults of A. whitfieldi used to infest the caged plants: T0 (0 adult = check), T1 (100 adults), T2 (200 adults), T3 (300 adults), T4 (400 adults). All caged plants were infested 21 days after transplantation and the evaluation started 14 days later one on every 2-week basis from September 18, 2014 to February 19, 2015. The growth parameters of the plant were assessed. The results showed that the intensity of damage caused by A. whitfieldi on the growth of young plants of J. curcas varied according to the treatment (i.e., according to the number of adult individuals infesting the plant at the beginning). The higher the number, the heavier the level of damage caused by the pest. So, the growth of the J. curcas plant was inversely proportional to the number of A. whitfieldi infesting individuals. There was also a positive linear correlation between the defoliation rate and the height of the seedlings. The status of this insect pest was confirmed by the results of this study.

“…Authors [5] rightly observed that in contradiction of the general belief that J. curcas was resistant to pests because of its toxicity, a large number of insects and other pests have been identified that can severely reduce growth and yield [6]- [8]. Calidea panaethiopica and Aphtona withfieldi are part of these insect pests [5] [9] [10].…”

“…It is a chewing insect that attacks the leaves of J. curcas' plants entailing their fall. Authors [5] showed that several studies had identified flea beetles of the genus Aphthona (Coleoptera: Chrysomelidae, Alticinae) as major pests of J. curcas in various regions in Africa [6] [9] [13]- [15]. These insect pests are known to be particularly damaging to young plants, which can die from continuous defoliation.…”

“…These insect pests are known to be particularly damaging to young plants, which can die from continuous defoliation. Even when the plant is not killed, growth and fructification are severely hampered [6] [9] [13] [15]. It is only just recently that [16] clarified the taxonomy of the genus Aphtona and described the species in West Africa as Aphtona whitfieldi Bryant [5].…”

The efficiency of an aqueous extract of Azadirachta indica's seeds and deltamethrin 12.5 EC was tested for the control of Calidea panaethiopica and Aphtona whitfieldi populations, two major insect pests of Jatropha curcas L. in Burkina Faso. This study was conducted in 2013 during the dry season and in 2014 during the raining season. In the laboratory, tests of toxicity by contact on paper blotter and by ingestion on organs of the plant and their repulsive effect on paper blotter were performed in vitro on the insect pests adults caught on J. curcas plantations as compared with controls. The aqueous excerpts of neem seeds were prepared at different lengths of steeping (12 h, 24 h and 48 h) and the deltamethrin 12.5 EC was diluted at different doses (4 ml, 8 ml and 16 ml/L). The results of this experiment showed the evidence of the efficiency of the doses 8 ml/L and 16 ml/L of deltamethrin 12.5 EC, and those of 24 h and 48 h for the excerpts of neem seeds. These efficient doses were evaluated in the field in 2013 and 2014. The highest decreases of C. panaethiopica (0.327) and of A. whitfieldi (0.501) populations were recorded with the 16 ml/L dose of deltamethrin in 2014 raining season. During the 2013 dry season, more insect pests were recorded (0.389 for C. panaethiopica M. Bidiga, S. Nacro 213 and 0.679 for A. whitfieldi) with that dose. But these results were not significantly different from those of 8 ml/L. Regarding the A. indica extracts, the best decrease of populations in the 1 st year (0.36 for C. panaethiopica and 1.278 for A. withfieldi) was recorded with the 48 h maceration. But in 2014 because of the effect of rainfalls that dose was less effective than that of 24 h maceration with 0.399 for C. panaethiopica and 1.208 for A. whitfieldi. The efficiency interval of the tested insecticides was two to three weeks in low or no rainfall conditions and one to two weeks in rainy season conditions.
