“…Neem oil efficiency in control of psyllids has been demonstrated in laboratory, causing both mortality and developmental changes in nymphs of Diaphorina citri (Kuwayama) (Weathersbee and Mckenzie, 2005) and Bactericera cockerelli (Sulc) (Flores-Dávila et al, 2011). In contrast with Weathersbee and Mckenzie (2005), we did not find dead insects on the Paraguay tea leaves, possibly indicating that death occurred after contact with the product without necessarily having ingested it.…”

Insecticidal activity of neem oil against Gyropsylla spegazziniana (Hemiptera: Psyllidae) nymphs on Paraguay tea seedlings

2016

Gyropsylla spegazziniana (Paraguay tea ampul) is one of the most important pests of Paraguay tea plants, and prohibition of synthetic insecticide use for control of this pest has led to the search for alternative methods. This laboratory study aimed to compare different control strategies for G. spegazziniana, utilizing a commercial neem seed oil product. Paraguay tea seedlings were treated with neem oil solution both pre-and post-infestation with 5 th instar nymphs. The systemic action of neem oil was also evaluated by treating plant soil with the neem oil solution, followed by transfer of the insects to plants 24 h post-treatment. Spray treatments were effective against the pest, especially post-infestation (80% mortality), demonstrating the potential of neem oil for control of the Paraguay tea ampul. No significant effects were observed with respect to systemic activity.Keywords: Gyropsylla spegazziniana, botanical insecticide, alternative control. Atividade inseticida de óleo de nim contra ninfas deGyropsylla spegazziniana (Hemiptera: Psyllidae) em mudas de erva-mate ResumoGyropsylla spegazziniana (ampola da erva-mate) é uma das principais pragas da erva-mate, tanto em áreas de plantio como em viveiros. A proibição do uso de inseticidas para o controle de pragas da cultura tem levado à busca de alternativas. Este trabalho visou avaliar comparativamente, em laboratório, estratégias de aplicação de um produto comercial à base de óleo de nim sobre G. spegazziniana, em solução a 5%. Os testes foram realizados em mudas de erva-mate, tratadas pré e pós-infestação com ninfas de 5º instar do inseto, para avaliação de contato. Também, avaliou-se a ação sistêmica do óleo de nim, aplicando-se a solução do produto no solo da muda de erva-mate, seguido da transferência dos insetos após 24 h. Verificou-se que os tratamentos via pulverização foram eficientes contra a praga, principalmente na aplicação pós-infestação (80% de mortalidade), comprovando o potencial inseticida do óleo de nim contra a ampola-da-erva-mate em mudas. Entretanto, em relação à atividade sistêmica, não foram observados efeitos consideráveis sobre a praga.Palavras-chave: ampola da erva-mate, planta inseticida, controle alternativo.

Plant metabolites have been used for many years to control pests in animals and to protect crops. Here, we reviewed the available literature, looking for the species of Mexican flora for which extracts and metabolites have shown activity against pest insects and parasitic nematodes of agricultural importance, as well as against nematodes that parasitize domestic cattle. From 1996 to 2018, the search for novel and eco-friendly biopesticides has resulted in the identification of 114 species belonging to 36 botanical families of Mexican plants with reported biological effects on 20 insect species and seven nematode species. Most plant species with detected pesticide properties belong to the families Asteraceae, Fabaceae, and Lamiaceae. Eighty-six metabolites have been identified as pesticidal active principles, and most have been terpenoids. Therefore, the continuation and intensification of this area of research is very important to contribute to the generation of new products that will provide alternatives to conventional pesticide agents. In addition, future studies will contribute to the recognition and dissemination of the importance of propagating plant species for their conservation and sustainable use.

En Sinaloa la producción de hortalizas y cucurbitáceas es una de las actividades agrícolas más importantes, por lo que cada año se usa un gran volumen de insecticidas químicos para el control de las plagas que atacan a estos cultivos. En el presente trabajo se dan a conocer a las principales plagas en la región, haciendo también un análisis sobre los insecticidas biorracionales que se utilizan para el control efectivo de las mismas. Se encontró que para el combate de Bemisia argentifolii Bellows & Perring (Hemiptera: Aleyrodidae) se utiliza el aceite de Neem al 0.2%., para ninfas de Bactericera cockerelli Sulc. (Homoptera: Psyllidae) guanábana Annona muricata L. (Annonales: Annonaceae) a dosis de 2500-5000 mg/L., para Liriomyza trifolii Burgess (Diptera: Agromyzidae) semillas de neem al 2%., y para Myzus persicae Sulzer (Hemiptera: Aphididae), aceite de colza a dosis de 920g/L (2% v/v)., para Frankliniella occidentalis Pergande (Thysanoptera: Thripidae) spinosad (conserve®) a 48-60 mg/L., para Phthorimaea operculella Zeller (Lepidóptera: Gelechiidae) el virus de la granulosis (105 CO/mL) combinado con neem (aceite emulsificable DalNeemTM y NeemAzalTM-T/S a dosis de 8 mg/L, cada uno). El uso de estos productos y las dosis dependen del tipo de plaga y del cultivo. En general estos productos causan mortalidades de insectos superiores al 95%, además de que tienen baja toxicidad sobre enemigos naturales, por lo que pueden usarse de manera individual o en combinación, en esquemas de control integrado de plagas de hortalizas e insectos vectores de enfermedades en el Norte de Sinaloa.
