“…Important factors that may have influenced the mortality of the mites are the plant part from which the secondary compounds were extracted and the form of application of the extract. Most of the plant's defense mechanisms are concentrated in the seeds, given their great importance as a vehicle for the propagation and survival of the species [13] . The higher or lower concentration of these compounds is generally determined by exogenous factors such as light, precipitation, place of cultivation, spacing, and sun, as well as by endogenous factors such as plant age and genetic variability in populations [14] .…”

The two-spotted spider mite, Tetranychus urticae Koch, is one of the most important mite species in the world, this specie is related to attacking more than 250 crops of economic importance. This pest can occur year-round but grows best in warmer and drier times. This way, the objective of this work was to evaluate the acaricidal potential of the extract of the jatropha pie (Jatropha curcas L), in different concentrations, aiming for the pest management of T. urticae. The solutions were sprayed under sheets of Canavalia ensiformis, with the support of the Potter tower, consisting of direct application. In the indirect route of application, the leaf discs were immersed in the extract solution of the J. curcas, placed on a paper towel to dry, and subsequently, transferred to Petri dishes, with cotton moistened on the bottom and sides. Females of T. urticae were transferred to leaf discs. Ten replicates were used per treatment, evaluating the mortality as a function of post-spraying time. At all concentrations tested, the direct application treatment was superior to the indirect application, causing greater mortality of the two-spotted spider mite in laboratory conditions.

“…Another study reported the effect of green fruit seed extracts and seed oils from fresh and dry fruits of J. curcas on adult green aphids Myzus persicae (S.) (Homoptera: Aphididae). Cabbage leaves (B. oleracea (L.) treated with 0.0, 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0% (w/v) of the extract in an ingestion bioassay were tested, with 61 and 71% mortality after 48-72 h at 2.5% [67].…”

The use of botanical extracts of the plant Jatropha curcas (Euphorbiaceae) represents a valuable alternative to control insect pests and avoid the detrimental effects on the environment and health that arise due to synthetic chemical insecticides. Thus, we conducted a systematic review to summarize the published evidence on the bioactivity of J. curcas against insect pests. Electronic databases were searched to identify studies that assessed J. curcas extracts against insect pests in various types of crops. We included 39 articles that reported the insecticidal and insectistatic activity of several botanical extracts from J. curcas against insects of eight different taxonomic orders. The evidence demonstrates that aqueous and methanolic extracts from seeds and leaves, seed oil, and petroleum ether seed extracts were effective against insect pests of stored grains, aphids of cabbage and sorghum, fruit flies, and desert locusts. The extracts caused high mortality, controlled the populations, reduced oviposition, diminished hatchability, and increased the antifeedant effect. However, the type of solvent used to obtain the botanical extract and the method of application (contact or food) are fundamental to increase its bioactivity. Therefore, botanical extracts from seeds and leaves of J. curcas should be considered as an alternative against insect pests and may be incorporated into integrative and sustainable management for insect control.
