“…The insecticidal properties of several plant extracts such as (Razavi and Ahmadi 2016). Toxicological effects of Ashwagandha have also been observed against the larvae/adults of various insects, for instance, leaf extracts against larvae of Culex quinquefasciatus (Karmegam et al 1997), leaf, stem, fruit and root extracts against adults of Callosobruchus chinensis (Gupta and Srivastava 2008), leaf, fruit and root extracts against adult Sitophilus oryzae (Yankanchi and Gadache 2010;Suvanthini et al 2012), green and red fruit, seed, fruit without seeds, leaf and root extracts against Anopheles stephensi, Aedes aegypti and Culex quinquefasciatus (Sakthivadivel and Daniel 2008;Bansal et al 2011), root, stem and leaf extracts against larvae of Tribolium castaneum (Arora et al 2011), and leaf extracts against larvae and adults of Oryzaephilus surinamensis (Madkaur et al 2013). Furthermore, acaricidal activity by the leaves of this medicinal plant against the larvae of deltamethrin resistant Hyalomma anatolicum (Singh et al 2014a) and fully engorged females of synthetic pyrethroid resistant Rhipicephalus microplus (Singh et al 2014b) have been shown.…”

Both seed and root extracts of the medicinal plant, Ashwagandha, Withania somnifera exhibit insect growth regulatory activity against the polyphagous pest, Pericallia ricini. Topical administration of W. somnifera seed and root extracts to last instar larvae of P. ricini disrupted moulting and metamorphosis, leading to a number of developmental abnormalities such as delay in larval-pupal and pupal-adult ecdysis, formation of larval-pupal, pupal--adult and larval-pupal-adult mosaics/chimeras, ecdysial failure, suppression of pupation and adult emergence and formation of abnormal pupae and adultoids. The treatment with seed extracts was more severe than that of root extracts as it completely suppressed the pupation and adult emergence. The results clearly suggest that the medicinal plant, W. somnifera acts as a potential insect growth regulatory (IGR) disrupting the moulting and metamorphosis as a consequence of interference with the endocrine system.

“…Ethanolic extracts of the leaves of Solanum xanthocarpum showed larvicidal activity against third and fourth instar larvae of C. quinquefasciatus (3) , with LC 50 values of 271.12 and 377.40mg/L, respectively. Sakthivadivel and Daniel (4) demonstrated the larvicidal effect of the ethanolic extract of leaves of Solanum trilobatum on fourth instar larvae of C. quinquefasciatus, with an LC 50 value >200mg/L. In a recent study (5) , methanolic extract and extract fractions from unripe S. lycocarpum fruit showed larvicidal effects against C. quinquefasciatus, with LC 50 values of 75.13-207.05mg/L.…”

Introduction:The larvicidal activity of oils, fatty acids, and methyl esters of Solanum lycocarpum fruit against Culex quinquefasciatus is unknown. Methods: The larvicidal activity of samples of ripe and unripe fruit from S. lycocarpum was evaluated against third and fourth instar larvae of C. quinquefasciatus. Results: The oils, fatty acids, and methyl esters of S. lycocarpum showed the greatest larvicidal effect (57.1-95.0%) at a concentration of 100mg/L (LC 50 values between 0.70 and 27.54mg/L). Conclusions: Solanum lycocarpum fruit may be a good source of new natural products with larvicidal activity.Keywords: Bioassay. Mosquito. Pesticide. Synthetic insecticides are used to control mosquito vectors of diseases in several parts of the world. However, resistance to synthetic insecticides has recently become problematic in vector control programs. Thus is important the development of new products, with the capacity to prevent or minimize the resistance, to combat insects (1) . Biological products represent alternative approaches for preventing the development of resistance in mosquitoes.Plants contain bioactive compounds with insecticidal properties that could be suitable for mosquito control applications (2) . Several species of the genus Solanum have demonstrated larvicidal and pupicidal activities against the mosquito Culex quinquefasciatus (3) (4) (5) . Solanum lycocarpum A. St. Hil. (Solanaceae) is popularly known as the fruit of the wolf and is widely distributed in the Brazilian Cerrado (6) . Solanum lycocarpum is commonly used in traditional medicine as a sedative and a treatment for epilepsy, asthma, diabetes, obesity, abdominal pain, renal pain, and high cholesterol levels (7) . Despite the widespread medicinal usage of S. lycocarpum and the reported insecticidal properties of other Solanum species, no studies have been conducted on the insecticidal activity of oils, fatty acids, and methyl esters obtained from the ripe and unripe fruit of S. lycocarpum.Fruit of S. lycocarpum A. St. Hil. were collected in São Sebastião do Oeste, Minas Gerais, Brazil in August 2011. The plant material was identifi ed by Dr. Alexandre Salino. A voucher specimen (BHCB 159397) was deposited at the Instituto de Ciências Biológicas Herbarium, Universidade Federal de Minas Gerais, Belo Horizonte, Minas Gerais, Brazil. Samples of the dried and powdered unripe (170.01g) and ripe (250.58g) fruit were subjected to oil extraction using a Soxhlet extractor with petroleum ether as the solvent (Vetec®, São Paulo, Brazil; 700mL, 6h). The extracted oils were concentrated in a rotary evaporator at 50°C under reduced pressure to produce 26.95g of oil of unripe fruit (OUF) and 29.09g of oil of ripe fruit (ORF).Fatty acids and methyl esters were isolated from S. lycocarpum via transesterifi cation (8) . OUF and ORF (2g each) were refl uxed with 1.0 mol/L methanolic NaOH solution for 30 min and extracted with ethyl ether. The aqueous phases were acidifi ed with 1.0 mol/L HCl solution and extracted with ethyl ether to obtain fatty...

Hyptis suaveolens and Leucas indica, two common weeds were selected for the present study, to reveal their probable cytotoxic potential. The meristematic root tips of Allium cepa were used for testing the cytotoxic property of the aqueous leaf extracts containing both polar and non-polar compounds, and that containing polar compounds alone, at different concentrations (0.125, 0.25, 0.5, 1 and 2 %) and at different time durations, using distilled water as negative control. Mitotic squash preparations were made using a standard protocol. The mitotic index of the treated root tip cells was found to be decreasing and the abnormality percentage was found to be increasing with increase in extract concentration when compared with the control. Maximum cytotoxicity was observed in the extract containing both polar and non-polar compounds. Both the tested plants were found to be cytotoxic. The abnormalities noticed were of both clastogenic (nuclear lesions, nuclear fragmentation, etc.) and non-clastogenic (aberrant cell wall formation at cytokinesis, ball metaphase, etc.) types. Both plant extracts were found to significantly (P \ 0.05) inhibit root growth of Allium cepa with an EC 50 value of 1.92 % (R 2 = 0.594) for Hyptis and 1.58 % (R 2 = 0.757) for Leucas. The results were also analysed statistically by using analysis of variance followed by appropriate post hoc tests. These two weeds are aromatic plants comprising of essential oils that are volatile, natural complex compounds characterized by a strong odour and formed as secondary metabolites. In nature, essential oils play an important role in the protection of the plants as insecticides by reducing their appetite for such plants. When specifically targeted the concept of effectively exploiting these weeds for the formulation of herbal insecticides/ pesticides may be possible in the near future.
