“…For instance, topical application of spearmint EO on adult T. molitor beetles has been shown to cause toxic effects [4]. Similar effects have been observed in a few species of coleopterans, such as Epicauta atomaria (Germar), in both adults and larvae [5]. Our data on the behavioural effect of spearmint EO expand existing knowledge about the impact of this EO on T. molitor larvae.…”

Beetle Tenebrio molitor L. (Coleoptera, Tenebrionidae) is a well-known pest of grain and flour in food stores and grocery shops. Recently, commercial cultivation of the insect was started for human food and animal feed. Behaviour control of this insect using natural repellents is promising both for grain protection and commercial cultivation. We analysed if natural products of plant origin, namely essential oils (EOs), could be used for this purpose. Behavioural tests were performed using EOs of six plants: thymus (Thymus vulgaris), eucalyptus (Eucalyptus globulus), spearmint (Mentha spicata), lavandin (Lavandula × hybrida), East-Indian lemongrass (Cymbopogon flexuosus), and clove (Eugenia caryophyllus). The most effective repellent for mealworm larvae was EO of spearmint, moderate activity showed that of clove and the least repellent were EOs of lemongrass thymus and lavandin. EO of eucalyptus caused almost no or very low effect. Six of the most abundant compounds of the EOs were selected for testing. The most effective single compounds were terpinene-4-ol and carvone, low-effective cis-sabinene hydrates and those of no significant activity were limonene, myrcene and γ-terpinene.

“…Estudos com o óleo essencial do louro relataram ações repelentes a insetopraga para armazenamentos de produtos alimentícios e também revelou que a composição química varia de acordo com a origem do óleo, o principal terpeno encontrado no óleo essencial de folhas de L. nobilis é, 1,8-cineol responsável pelas propriedades inseticidas (8) . Outro estudo com o óleo vegetal mostrou ser repelente a besouros (18) esses óleos além de repelentes são tóxicos e conseguem inibir a reprodução (19) .…”

A procura por plantas medicinais tem crescido devido a seus compostos bioativos, propriedades antimicrobianas e, em particular pelo apelo ecológico. Podem ser alternativas para o controle de diferentes insetos, com a vantagem de serem naturais e, eventualmente, não prejudicarem o ambiente. Objetivou-se com este trabalho avaliar a ação repelente de Laurus nobilis L., sobre Nauphoeta cinerea (Olivier, 1789). Foram utilizados três indivíduos, sendo dois marcados com corretivo líquido à base de água, sendo um com tinta azul e o outro com tinta vermelha. Um terceiro exemplar permaneceu sem marcação. Estes foram mantidos em caixa plástica, cuja tampa foi retirada e colocada um sombrite, o fundo da caixa foi dividido em quadrantes numerados. Foram ofertados alimento e água ad lib. Em um dos quadrantes foi depositada pequena porção de diferentes tipos de extrato vegetal de Laurus nobilis L. Os animais foram acompanhados por um período de duas horas. Os dados apontaram maior eficácia com o uso do vegetal in natura e a seco com o mesmo nível de eficácia em repelência. A utilização de extratos vegetais utilizando Laurus nobilis pode ser uma alternativa na repelência de insetos; não apenas pelo fácil preparo, mas, especialmente quando a meta é a sustentabilidade, quer seja econômica, social e ambiental.

“…2,[6][7][8] In addition, plant essential oils and other substances that are easy to vaporize at room temperature are used as fumigants because they can enter insects through stomata. 9,10 Matrine, a quinolizidine alkaloid extracted from the root of Sophora flavescens, is the most registered botanical pesticide in China. 11 It has excellent insecticidal activity, especially against aphids, 12,13 showing contact poisoning, stomach poisoning and antifeeding activities.…”

Background: Although matrine is widely used, its absorption and transport mechanisms in crops remain unexplored. In this study, three methods including foliar application, hydroponics and seed immersion were used to investigate whether matrine molecules could enter into plants through different channels, and to further resolve its transport characteristics. The systemic activity of matrine also was evaluated.Result: Matrine was quickly absorbed and transported downwards after the leaves of wheat or peppers were treated, and also accumulated and transmitted upwards by roots. It was not only absorbed by seeds, but also appeared continuously in young roots and leaves in both plants for nearly 20 days. There were some differences in the uptake and conduction of matrine between pepper and wheat: matrine concentrated in pepper upper leaves with less delivered downwards to roots than in wheat, and also transduction of matrine in pepper lower leaves upwards to upper leaves was less than in wheat. Matrine had systemic activity, with LC 50 of 361.99 and 904.24 ∼g•mL −1 against Rhopalosiphum padib on wheat and Myzus persicae (Sulzer) on pepper plants at 48 h, separately.Conclusion: Matrine can be absorbed by the roots, seeds and leaves of plants, and transmitted bidirectionally to any organs, presenting satisfactory systemic poisoning activity against aphids. It is of great significance to develop new formulation products of matrine and promote its commercialized value.
