“…mortality) levels against beneficial insects. Indeed, botanical compounds have been reported to be selective against beneficial insects, 36,37,56,57 but recent investigations have detected unintended effects of these compounds that have hampered their wider use 34,35,58,59 . The findings described here revealed that F. carica branch and leaf extracts were strongly selective and did not affect two pollinator bee species ( A. mellifera and P. helleri ) or three predatory natural enemy species (the ladybeetles E. connexa and Co. maculata , and the lacewing Ch.…”

“…The extract aliquots were dissolved in a mixture of water and 1.25% (v/v) DMSO and Tween 20 and applied to Petri dishes (9 cm in diameter) that had their bases covered with filter paper. The filter paper was left to air dry for 1 h, as previously described elsewhere 36,37 . Groups of five ladybeetles ( Co. maculata or E. connexa ) at 10–30 days of age were added to the Petri dish (i.e.…”

BACKGROUND Using plant‐based extracts and their constituents has been suggested as an alternative tool to replace or integrate with the synthetic compounds used to manage insect pests. Here, we evaluated the potential of extracts obtained from Ficus carica Linn (Moraceae) branches and leaves against the Neotropical brown stink bug, Euschistus heros, one of the most prevalent insect pests in soybean fields. We further isolated and evaluated the toxicity of the extracts' major components against E. heros. Additionally, by using computational docking analysis and toxicological approaches, we assessed the physiological basis for the selectivity of these extracts against beneficial insects such as pollinator bees (i.e. Apis mellifera and the Neotropical stingless bee Partamona helleri), ladybeetles (Eriopis connexa and Coleomegilla maculata), and lacewings (Chrysoperla externa). RESULTS Our results demonstrate that branch (LC50 = 5.9 [4.7–7.1] mg mL–1) and leaf (LC50 = 14.1 [12.5–15.4] mg mL–1) extracts exhibited similar toxicity against E. heros. Our phytochemical analysis revealed psoralen and bergapten furanocoumarins as the major components of the extract. Based on our computational predictions, these molecules' differential abilities to physically interact with the acetylcholinesterases of E. heros and beneficial insects play relevant roles in their selectivity actions. The estimated LC90 values of branch (30.0 mg mL–1) and leaf (30.0 mg mL–1) extracts killed less than 12% of the beneficial insects. CONCLUSION Overall, our findings revealed that furanocoumarin‐rich extracts obtained from F. carica extracts have the potential to be used as alternative tools in the integrated management of stink bug pests. © 2021 Society of Chemical Industry.

Clove (Syzygium aromaticum L. Myrtaceae) is an aromatic plant widely cultivated in tropical and subtropical countries, rich in volatile compounds and antioxidants such as eugenol, β-caryophyllene, and α-humulene. Clove essential oil has received considerable interest due to its wide application in the perfumery, cosmetic, health, medical, flavoring, and food industries. Clove essential oil has relevant biological activities to human health, including antimicrobial, antioxidant, and insecticide. This review describes the effect of the extraction method (hydrodistillation, steam distillation, ultrasound-assisted extraction, microwave-assisted extraction, cold pressing, and supercritical fluid extraction) on the chemical composition of essential oil and its correlation with their biological activities. Likewise, are summarized the main compounds and their reported biological activities. Furthermore, the main applications in clove essential oil in the food industry are presented. Finally, this review presents the new biological activities such as anti-inflammatory, analgesic, anesthetic, antinociceptive and anticancer, which are beneficial for human health. This review aims to compile the effect of different methods of extracting clove essential oil on chemical composition, food applications, as well as a current description of biological activities of interest to human health. Biological activities have increased interest in research into this essential oil and its future applications in the food or pharmaceutical industry.

Aphids are the major pest on crops. Use of chemical pesticides create problems. Chemical pesticides affect the human health, environment and also affects non target organisms. Natural insecticide produced from plants are more promising. The Cymbopogon citratus and Hibiscus rosa sinensis are very important plant which have great effect on insects. The aim of this review to tell about essential oil and extracts which affects insect growth and how much it is effective. The problem of agriculture crop was pests and these pests are responsible for damaging crops and effect nutritive value. Lemon grass oil repels insects like mosquitoes, aphids due to which it contains citral and also myrcene, citronella, citronellol, and geraniol. The essential oil is derived from aromatic plants has observed as risk free alternatives.
