“…According to the results here obtained, the odor of essential oil and its components is repulsive to S. granarius. Terpenoids cross the insect body barrier through the spiracles and trachea [22,44] and could lead to important consequences in the control of insect pests of stored grains [65]. Our results show that S. granarius adults are repelled by lemongrass essential oil, geranyl acetate, and citral, suggesting that the use of lemongrass essential oil and its components may introduce an innovative approach to control this pest through manipulation of its foraging and avoidance behavior.…”

In the present work, we evaluate the toxic and repellent properties of lemongrass (Cymbopogon citratus (DC. ex Nees) Stapf.) essential oil and its components against Sitophilus granarius Linnaeus as an alternative to insecticide use. The lethal dose (LD50 and LD90), survivorship, respiration rate, and repellency on adults of S. granarius exposed to different doses of lemongrass oil and some of its components were evaluated. The chemical composition of the essential oil was found to have the major components of neral (24.6%), citral (18.7%), geranyl acetate (12.4%), geranial (12.3%), and limonene (7.55%). Lemongrass essential oil (LD50 = 4.03 µg·insect–1), citral (LD50 = 6.92 µg·insect–1), and geranyl acetate (LD50 = 3.93 µg·insect–1) were toxic to S. granarius adults. Survivorship was 99.9% in insects not exposed to lemongrass essential oil, decreasing to 57.6%, 43.1%, and 25.9% in insects exposed to LD50 of essential oil, citral, and geranyl acetate, respectively. The insects had low respiratory rates and locomotion after exposure to the essential oil, geranyl acetate, and citral. Our data show that lemongrass essential oils and their components have insecticidal and repellent activity against S. granarius and, therefore, have the potential for application in stored grain pest management schemes.

“…Furthermore, it has been reported that the host-plant preference of nymphs varies according to the region and nymphal instar for Philaenus spumarius L., Neophilaenus campestris (Fallén), and Aphrophora alni (L.) [ 16 ], as well as varying over time. Volatile compounds from grasses also influence the feeding of Mahanarva spectabilis (Distant) [ 22 ].…”

The foam produced by nymphs of Poophilus costalis on eleven different host plants belonging to eight families on St. Xavier’s College campus in India was studied over five months. The chemical composition and antimicrobial activity of these biofoams were investigated. The results revealed that P. costalis preferred Theporsia purpurea and Mimosa pudica for laying their eggs and producing foam, over the other tested plants. P. costalis produce their foam on either nodes or internodes on monocotyledons (30%) (p < 0.05), whereas on dicotyledons, they produce more foam on the stems (63.8%) than on the leaves (6.2%) (p < 0.01). The number of nymphs in each piece of foam from P. costalis varied from 1 to 3 (mean = 1.8 per plant). They produced their foam (5.7 to 45.2 cm) from the ground level on a plant. The length and breadth of a piece of foam ranged from 1.0 to 3.9 cm and 0.6 to 4.7 cm, respectively. The foam tended to be cooler than the environment. Qualitative profiling showed that the foam consists of carbohydrates, including maltose; trypsin; amino acids; protease. The foam was also analyzed using a spectrophotometer, Fourier transform infrared spectroscopy (FT-IR), gas chromatography–mass spectroscopy (GC-MS), and high-performance liquid chromatography (HPLC). The antimicrobial activity of the biofoam was the greatest against Staphylococcus aureus, the growth of which was reduced by 55.9 ± 3.9%, suggesting that the foam could be used as an antimicrobial product. However, no activities were observed against Fusarium oxysporum and Candida albicans.

“…In the present work, the aqueous extract of the E. globulus was not attractive to M. spectabilis as compared to clean air; however, when compared to the host plant combination, there was no change.In the olfactometer tests, the combinations of the host plant with the aqueous extracts of garlic, rue, cinnamon, lemongrass, cloves, and thyme did not alter the behavior of the M. spectabilis adults significantly. A similar situation was reported bySilva et al (2019), who observed that VOCs from P. purpureum cv. Roxo Botucatu, Panicum maximum cvs.…”

“…In this study, we investigated whether the volatile com-pounds present in the aqueous extracts of the nine species of plants with insecticidal potential, applied on the forage host, would be able to alter the adult spittlebugs (M. spectabilis) choice of pastures, influencing their behavior of attraction or nonattraction. Elephant grass was chosen since it can release some specific odors that have the potential to attract M. spectabilis (SILVA et al, 2019). SINGH et al, 2005;.…”

Evaluation of lethal and repellent action of aqueous vegetable extracts for the control of spittlebugs (Hemiptera: Cercopidae)

Spittlebugs (Hemiptera: Cercopidae) are species considered to be the main pests of forage grasses throughout Tropical America. In Brazil, Mahanarva spectabilis (Distant) is the main and most limiting pest associated with elephant grass (Pennisetum purpureum Schum.). These insects have the potential to generate great economic losses for the milk and meat production chain, harming producers. Among the spittlebugs control tactics, the use of resistant grasses, biological control and the application of synthetic insecticides in adults are the best known methods. The use of synthetic insecticides is economically viable only when combined with other spittlebugs control strategies, but they are environmentally unsafe products, so it is necessary to research tactics that are less aggressive to the environment, socially viable and of low cost for mainly small farmers. In this context, the insecticidal and repellent action that plant compounds have against different insect-pest species stands out. Thus, the objectives of this research were to evaluate whether aqueous extracts of the aromatic plants A. sativum, R. graveolens, C. verum, C. citratus, S. aromaticum, I. verum, E. globulus, N. tabacum and T. vulgaris have an insecticidal effect on spittlebug nymphs and the choice of spittlebugs adults can be altered for elephant grass, by attraction or non-attraction, in olfactometry tests. In the first stage of the research, the insecticidal effect of the extracts on nymphs of M. spectabilis was evaluated. The results indicated that the tobacco extract was the most effective among all nine tested. At a concentration of 20%, after 48 hours, it reached an efficiency of 76%. Then, bioassays were carried out comparing 5 concentrations of tobacco extract (5%, 10%, 15%, 20% and, 25%), where the extract in the concentration of 25% reached an efficiency greater than 92%. As for the extraction methods, the infusion and decoction methods were shown to be equivalent to the standard extraction method (UAE). Tobacco extract is recommended as a strategy to control M. spectabilis, at a concentration of 25%, with its extraction by infusion and decoction. In the second stage, olfactometry bioassays were performed. The combinations of aqueous extracts applied to the host plant were tested against fresh air and against the host plant without the extract. The aqueous vegetable extracts of tobacco, star anise and eucalyptus were not attractive for the M. spectabilis, and can be used as a management tactic in the case of elephant grass.
