“…An important strategy explores the use of bioactive compounds from plants to develop new acaricides (Roh et al 2003;Santos et al 2012a, b;Štefanidesová et al 2017;Rodriguez-Vivas et al 2018;Vinturelle et al 2017). Research on plant bioactive compounds can lead to the identification of new molecules presenting different modes of action, biological targets and synergy in comparison to current commercial products (Benelli and Pavela 2018;Pavela 2015;Rattan 2010;Agwunobi et al 2020).…”

The indiscriminate use of acaricides is a problem worldwide and has increased the selection of acaricide-resistant tick populations. The goal of this study was to evaluate the acaricide effects of two essential oils (from Schinus molle and Bulnesia sarmientoi) using the larval immersion test on three Rhipicephalus tick species. Rhipicephalus evertsi, Rhipicephalus appendiculatus and Rhipicephalus pulchelus ticks collected in Kenya, without history of acaricide exposure, were tested, as well as individuals from two populations of Rhipicephalus microplus (with or without history of acaricide exposure), for comparison. The sample most resistant to the treatments was a population of R. microplus with previous acaricide exposure, whereas the least tolerant sample was a strain of the same species that never had contact with acaricides (Porto Alegre strain). Interestingly, the field tick samples without previous acaricide exposure responded to essential oils with a mortality profile resembling that observed in the acaricide-resistant R. microplus field population, and not the susceptible Porto Alegre strain. The essential oil of B. sarmientoi and its two components tested (guaiol and bulnesol) caused the highest mortality rates in the tested species and are potential molecules for future studies on control methods against these species.

“…The cracks at the sensilla socket became more prominent at the concentration of 40 mg/mL with partial disfiguration of part of the slit's edge. Similarly, drastic sensilla disturbance and cuticular disruptions in the form of cracks were observed in the treated group of H. longicornis treated with lemongrass essential oil (Agwunobi et al 2020a). Significant distortion in the sensilla with crack-like marks on the sensory placode and campaniform were observed across the antennae segments of honey bees treated with pesticides (Chakrabarti et al 2015).…”

“…Lemongrass essential oil has shown pesticidal properties against mosquitoes, flies, and the larvae and adults of Rhipicephalus microplus (Chauhan et al 2016;Manh et al 2020;Sheziyna et al 2020). Additionally, our previous investigation demonstrated the acaricidal effects of lemongrass essential oil on the mortality and external morphology of H. longicornis and revealed lethal concentrations (LC 50 ) of 29.21, 28.18, 28.06 mg/mL for the adults, nymphs, and larvae, respectively (Agwunobi et al 2020a), and also its effect on the expression profiles of genes of the detoxification enzyme glutathione s-transferases in H. longicornis (Agwunobi et al 2020b). The present study evaluated the ultrastructural and morphological alterations induced by the essential oil of lemongrass on the midgut, integument, and the Haller's organ of the unfed adult H. longicornis tick with the purpose to aid the further understanding of the acaricidal potentials of lemongrass essential oil.…”

“…The concentrations of lemongrass essential oil used for the treated groups via the AIT were based on the lethal concentration LC 50 (29.21 mg/mL) for adult H. longicornis as previously determined during the preliminary test by our previous investigation (Agwunobi et al 2020a). Numerous concentrations were evaluated by dilution of the essential oil with an aqueous solution containing 50% ethanol.…”

Haemaphysalis longicornis Neumann is a widely distributed species known for its capacity to transmit pathogens of medical, public health, and veterinary importance. Due to the environmental contamination caused by synthetic acaricides, plant essential oils have emerged as a promising alternative to manage tick infestation. This study evaluated the ultrastructural and morphological changes induced by Cymbopogon citratus Stapf (lemongrass) essential oil on adult H. longicornis tick. The concentrations of lemongrass essential oil used for the treatment via the adult immersion test were from 10 to 40 mg/mL. The most significant alterations 24 h post-exposure include the proliferation of lysosomes, reduction in the number of the rough endoplasmic reticulum, disorganization of the microvilli, the disappearance of lipid droplets and hematin granules, and cytoplasmic vacuolization (midgut); a thinner endocuticle and epicuticle, the deletion of the subdivision’s demarcation of the procuticle, disfiguration of the lamellar arrangements of the exocuticle, and cytoplasmic vacuolization of the epithelial cells (integument); cracks on the sensilla sockets, the detachment of one or two sensilla in the anterior pit, and partial disfiguration of part of the slit’s edge (Haller’s organ). These results reflect the acaricidal properties of the essential oil and could be an alternative means of tick control.

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.
