“…K. Schum. reduziu a sobrevivência pupal de P. xylostella em 60%, enquanto os extratos aquosos de A. edulis e A. intermedia e os extratos etanólicos de A. edulis, A. sessilis e A. intermedia não demonstraram influência sobre a sobrevivência dessas pupas (Peres et al, 2017;Da Silva et al, 2020). Os extratos metanólicos das folhas de Palicourea rigida Kunth.…”

“…Esse microlepidoptero é um dos principais inseto-daninho dos cultivares de brassicas, que pode gerar um prejuízo mundial de 4 a 5 bilhões de dólares anualmente com o manejo e produções de brássicas perdidas (Zalucki et al, 2012). Nos últimos dez anos, diversas plantas foram testadas quanto à atividade inseticida frente aos parâmetros biológicos de P. xylostella, entre elas Amaranthaceae, Acoraceae, Piperaceae, Solanaceae, Annonaceae, Fabaceae, Euphorbiaceae, Crassulaceae, Meliaceae, Asteraceae, Poaceae e Rubiaceae (Trindade et al, 2011;Couto et al, 2016;Hidayati et al, 2016;Boo et al, 2018;Fonseca et al, 2018;Matharu & Mehta, 2018;Ahmad et al, 2019;Cerda et al, 2019;Karimzadeh & Rabiei, 2020;Ningsih et al, 2020;Da Silva et al, 2020;Mpumi et al, 2020). Sendo essa última família de grande importância econômica e terapêutica no Brasil (Valli et al, 2016).…”

Extratos botânicos com propriedades inseticidas buscam minimizar os problemas provocados pelo uso incorreto e muitas vezes exagerado dos agrotóxicos. Dependendo da concentração utilizada e do método de extração, certos extratos podem provocar diversas reações sobre os insetos-daninhos. Sendo assim, o presente trabalho teve por objetivo avaliar a toxicidade dos extratos aquosos elaborados por maceração e infusão de Psychotria capillacea, Psychotria deflexa e Psychotria leiocarpa sobre ovos, larvas e pupas de Plutella xylostella. Foram utilizados sete tratamentos para avaliar a toxicidade dos extratos, sendo: 1) infusão P. capillacea, 2) infusão de P. deflexa, 3) infusão de P. leiocarpa, 4) maceração P. capillacea, 5) maceração de P. deflexa, 6) maceração de P. leiocarpa e 7) água destilada (controle). Larvas de terceiro instar de P. xylostella e pupas com até três dias de formação receberam aplicação tópica dos tratamentos, enquanto fragmentos de couve contendo ovos desse inseto foram imersos nos tratamentos. Os resultados demonstraram que os extratos aquosos por infusão e maceração de P. capillacea e P. leiocarpa e P. deflexa não apresentaram toxicidade significativa sobre as larvas e pupas de P. xylostella, enquanto extratos elaborados por maceração reduziram a sobrevivência de ovos desse inseto. Observou-se que os extratos macerados causaram a mortalidade nas primeiras 46 horas e as infusões foram mais efetivas após esse período. Sendo assim, outros testes devem ser realizados para elucidar a eficiência dos extratos de Psychotria sobre os parâmetros biológicos e comportamentais de P. xylostella, tendo em vista que novas técnicas de extração devem ser exploradas.

“…Promising plants, such as those in the families Meliaceae, Rutaceae, Asteraceae, Annonaceae, Labiatae and Canellaceae, have chemical compounds with repellent or insecticidal potential, as reported by Jacobson [10]. Studies involving plant extracts with insecticidal properties indicate changes in the biological characteristics of insects, such as mortality [11][12][13] changes in food [14,15] or oviposition [15,16] preferences, deformities, and morphological and physiological transformations of P. xylostella [11,[17][18][19][20].…”

The feeding activity of Plutella xylostella in brassica crops can lead to large losses; thus, pesticides that prevent feeding during the larval stage or prevent the metamorphosis of this insect can be used for its control. In this study, the effects of two types of aqueous extracts of Tradescantia pallida on the different life stage of P. xylostella cycle were tested; neither of the two aqueous extracts, which were obtained by infusion and maceration, had been tested against P. xylostella. The biological variables evaluated were larval and pupal duration and viability, pupal weight, sex ratio, longevity of females, fecundity, fertility and oviposition period. There was no significant difference in the duration of the larval phase of P. xylostella between the bioassay treatments; however, larval viability was lower when the individuals were exposed to both types of T. pallida extracts. Reduced pupal viability was observed among the individuals treated with the application of the extracts. Treatment with the aqueous extract obtained by infusion caused the lowest pupal weight, fecundity, and fertility and longevity among females. The results obtained in this study allow us to propose the bioextract as an alternative for pest management, emphasizing the technique for small producers and/or organic.

The high consumption rate of vegetables stimulates the cultivation and increases the demand regarding the adequacy of the production processes. The attack of the pest Plutella xylostella causes high losses by reducing product quality, typifying a phytosanitary problem. This study aimed to verify the bioactivity of aqueous extracts of leaves of Jacaranda decurrens and Jacaranda mimosifolia at concentrations of 5, 10, and 15% on the insect. The choice test was carried out at the laboratory to determine the food effect of plant extracts and evaluate changes in the life cycle of insects exposed to active compounds through the analysis of biological parameters. Plant extracts of J. decurrens and J. mimosifolia presented with phagodeterrent classification in the choice experiments. The three J. decurrens extract concentrations promoted a prolongation of larval and pupal duration, while the duration of individuals treated with J. mimosifolia at 10% was significantly reduced. Occurred reduction in larval survival of individuals treated with aqueous extracts of J. decurrens and J. mimosifolia. Eggs from treatments with aqueous extract of J. decurrens and J. mimosifolia had reduced survival. Pupal survival of individuals treated with extract at 15% showed a significant reduction compared to the treatments at 5% and 10%. Pupae from the treatment with aqueous extract of Jacaranda mimosifolia showed a reduction in biomass in the treatment at 15% differing from the control e 5%. Thus, the aqueous extracts of the species J. decurrens and J. mimosifolia show insecticidal potential in the tests performed on P. xylostella.
