“…53 As another alternative to conventional chemical control of ticks, promising results have been obtained with the use of organonatural substances -"green acaricides" -in the control of vectors of medical and veterinary importance, including R. sanguineus. 30,35,36,[54][55][56][57] Botanical substances with acaricidal properties meet the need for less polluting and biodegradable compounds, which leads to a reduction in the aggression to the environment exerted by conventional chemical acaricides and provide an environmental awareness of the need to preserve natural resources.…”

“…The impregnated papers methodology, also known as larval packet test (lpt), was used. This method was adapted by Fernandes and Freitas 30 from previously described methods, mainly those of FAO, 32,33 Fernandes 6,34 and Fernandes et al 35,36 Adaptations of the FAO method were carried out with the aim of increasing practicality and reducing costs, but without loss of efficiency, having been tested and improved, with satisfactory results in the evaluation of the acaricidal activity of chemical and botanical substances on different species of Ixodidae, e.g., R. sanguineus, R. microplus and Amblyomma cajennense. Further details of the methodology can be found in Fernandes and Freitas.…”

The Brown dog tick Rhipicephalus sanguineus is the most reported and geographically widely spread tick in the world, presenting a great medical and veterinary importance, mainly because the ability to transmit various diseases to its hosts, causing great harm to pets, but also risks to public health, due to the transmission of emerging pathogens to humans. In order to monitor the resistance or susceptibility of R. sanguineus to acaricides, and contribute to integrated control measures for this vector, the activity of 14 commercial acaricidal products on larvae from the city of Goiânia, Goiás, Brazil were studied. Although these products are already sold as acaricides, their cost-benefit efficiency has been questioned by dog breeders and kennel owners. R. sanguineus larvae were obtained from engorged females collected in naturally infested urban environments. The susceptibility of the larvae was evaluated by the larval packet test (lpt) method. Bioassays were carried out in quadruplicate, at 27 ± 1oC, RH ≥ 80% and photoperiod of 12 hours. About 50 larvae, from 14 to 21 days of age, were conditioned in filter paper envelopes, impregnated with different concentrations of acaricide products, obtained from dilution of stock solutions. The control group used the same amount of larvae, submitted to envelopes treated only with distilled water. A status of resistance of R. sanguineus larvae to acaricide formulations was evidenced for Cypermethrin, Cypermethrin + Piperoline Butoxide, Deltamethrin, Permethrin (after 24h of exposure), in the dosages recommended by the manufacturing laboratories, as they promoted a mean mortality of only 58.36%, 71.36%, 48.7%, and 64.5% of the submitted larvae, respectively, Amitraz providedof only 78.8 and 88.00% (After 24 and 48 hours of exposure to the acaricide, respectively), characterizing a status of possible development of resistance to this acaricide. The other evaluated products (Dichlorvos + Cypermethrin, Chlorfenvinphos + Dichlorvos + Alkyl + Xylol, Chlorpyrifos + Cypermethrin hi-cis, Fipronil, Chlorpyrifos, Cypermethrin + Chlorpyrifos + Citronellal, and Trichlorfon + Coumaphos + Cyfluthrin; and Diazinon) showed higherindices, configuring the susceptibility status to these acaricide formulations. No significant mortality was found in the control groups. The ideal concentrations to kill R. sanguineus larvae (CL99) referring to products that showed low acaricidal activity were statically calculated and are presented in this study. The present work, confronted with previous studies, ratified the real evolution of resistance to synthetic chemical acaricides in local populations of R. sanguineus.

RESUMO:Tetranychus urticae Koch (1836) (Acari: Tetranychidae), conhecido como ácaro rajado, é uma praga que pode reduzir a produção de frutos do morangueiro em até 80%. O controle desta praga por meio de acaricidas sintéticos tem proporcionado à destruição de organismos benéficos e o desenvolvimento de populações resistentes. Como alternativa ao controle tradicional, este trabalho teve como objetivo avaliar os efeitos do extrato de Sapindus saponaria e de solução sabão sobre a oviposição e mortalidade de fêmeas de T. urticae. Os ácaros foram pulverizados, com auxílio da Torre de Potter, usando formulações do extrato/solução sabão a 1, 2, 3, 4, 5% (m/v) e avaliados em 24, 72 e 120h. Verificou-se que o extrato de S. saponaria apresentou maior eficiência (CL 50 , 1,18%) do que a solução sabão (CL 50 , 1,31%). Em relação à atividade ovicida, o maior efeito foi observado com a formulação a 5% (m/v) após 120h, tanto para o extrato de S. saponaria (60,9%) quanto para solução sabão (84%). Os resultados observados, em condições de laboratório, são favoráveis à utilização do extrato de S. saponaria e de solução sabão no controle de T. urticae em programas de manejo fitossanitário para a cultura do morango.

“…Périco et al (2015) reported that plants of the Sapindaceae family have saponins and tannins. The high saponin content of Sapindaceae fruits has foam-forming properties and can be used as an insecticide (Fernandes et al, 2007), which may cause an inhibitory effect on P. xylostella oviposition. Saponins are substances mainly related to the defense system.…”

The indiscriminate use of synthetic insecticides caused an increase in the resistance of Plutella xylostella (Linnaeus, 1758) (Lepidoptera: Plutellidae) to almost all classes of insecticides, as well as affected the environment and non-target organisms. Thus, the search for less harmful alternatives with the purpose of reducing the application of these insecticides has become a priority. A possible alternative to reduce the use of synthetic insecticides is by using botanical insecticides, given the thousands of existing compounds derived from secondary metabolism in plants. In this study, we tested the following hypotheses: (i) the aqueous and ethanolic extracts of native plants reduce the food consumption of larvae and oviposition of adults of P. xylostella; (ii) these botanical species can act as potential plant insecticides. The objective of this work was to evaluate the effect of plant extracts on the feeding preference of larvae and oviposition of adults of P. xylostella. For this, cabbage discs treated with aqueous and ethanolic extracts of Schinus terebinthifolius, Annona coriacea, Annona crassiflora and Serjania marginata were given to larvae. The concentrations used for the aqueous extracts were of 5 and 10 mg mL-1, and for the ethanolic extracts were of 1 and 5 mg mL-1. Both extracts of the four tested plant species showed oviposition suppressed. The extract of S. marginata showed the lowest rates of suppression. All treatments with ethanolic extracts showed a phagodeterrant effect being that the aqueous and ethanolic extracts of A. crassiflora and S. terebinthifolius were the most effective as antifeedants on third instar larvae by P. xylostella.
