“…Such results have to confirm the insecticidal activity of this genus ever reported for S. frugiperda and other insects (Bogorni and Vendramim, 2003;Bogorni and Vendramim, 2005;Conceschi et al, 2011;Cunha et al, 2006;2008;Mikolajczak and Reed, 1987;Nebo et al, 2010;Roel et al, 2000b;Thomazini et al, 2000;Wheeler and Isman, 2000). Reports regarding the biological activities of the substances and / or extracts from plants of this genus, such as "antifeedant" and insecticidal properties, comparable to azadirachtin are available (Bogorni and Vendramim, 2005;Cunha et al, 2006;Mikolajczak and Reed, 1987).…”

The objective of this study was to evaluate the effects of the methanolic extracts from the leaves, bark and flowers of Trichilia silvatica on Spodoptera frugiperda. Also, it was use in evaluating the total phenolic and flavonoid content of methanolic extracts. We also reported chemical study on the most active extract. Corn leaves were immersed in a 1% methanolic extract solution and fed to second instars of S. frugiperda. The extract of the T. silvatica (LTS) leaves decreased the viability of the larva, prolonged larval duration, affected the pupal biomass, decreased the period of oviposition and the number of eggs as well as affected the egg viability. The methanolic extract of the T. silvatica (BTS) bark decreased the larval viability, oviposition period, number of eggs and egg viability. The flower extract of T. silvatica (FTS) decreased the larval viability and period of oviposition. In relation to the constituent contents, the methanolic extract of the leaves showed highest total phenol (233.37 mg gallic acid/g of extract) and flavonoid (53.17 mg quercetin/g of extract) content. The chemical study of the FTS resulted in α-tocopherol, sitosterol 3-O-glucopyranoside, mustakone and N-metilproline. Our results indicate that the extracts affected the biology of S. frugiperda, with LTS being the most promising.

“…However, mass trapping would likely be most effective when used in conjunction with recommended insecticides. Other pest control approaches have been studied and documented, notably the potential use of biological control agents (predators, parasitoids and entomopathogens which are described in ''Biological control of T. absoluta in South America'' section), resistant plants (de Resende et al 2006;Pereira et al 2008;Campos et al 2009;Oliveira et al 2009;Maluf et al 2010) and botanical insecticides (Moreira et al 2004;da Cunha et al 2005da Cunha et al , 2006GoncalvesGervasio and Vendramim 2007;da Cunha et al 2008). However, despite increasing interest in such control approach options (notably because smaller populations of T. absoluta are usually observed in organic vs. conventional systems, Medeiros 2007;Medeiros et al 2009b) they are only scarcely used.…”

Biological invasion of European tomato crops by Tuta absoluta: ecology, geographic expansion and prospects for biological control

The tomato leafminer Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is a devastating pest of tomato originating from South America. After its initial detection in eastern Spain in 2006, it rapidly invaded various other European countries and spread throughout the Mediterranean basin. If no control measures are taken, then the pest can cause up to 80-100% yield losses in tomato crops in recently invaded areas and may pose a threat to both greenhouse and open-field tomato production. The exceptional speed and extent of T. absoluta invasion have called for studies documenting its biology and ecology, while indicating an urgent need for efficient and sustainable management methods. The development of approaches to manage T. absoluta would be facilitated through a detailed revision of information on this pest in its area of origin. This review combines information on the invasion by T. absoluta, its ecology, and potential management strategies, including data that may help the implementation of efficient biological control programs. These programs, together with a variety of other management tactics, may allow efficient integrated pest management of T. absoluta in Europe and Mediterranean Basin countries.

“…Decreased feeding in insects has been reported in response to different Trichilia plant extracts (Ramírez et al 2000, Wheeler et al 2001, Rodriguez et al 2003. Many species of Trichilia have effects on insects, including inhibition and regulation of growth (Koul et al 2004), cytotoxic activity (Roel et al 2000, Souza and Vendramim 2001, Cunha et al 2008, and insecticidal activity (Matos et al 2009, Nebo et al 2010.…”

Plutella xylostella L. is one of the main agents to cause damages to plants of Brassica genus, provoking negative impacts in cultures. The use of botanical extracts in plants protection has been related in literature, however, their use in the species analyzed in this study is not yet reported. We assessed the effect of aqueous and methanolic extracts of the species: Schinus terebinthifolius Raddi ( -branco), occuring in the state of Mato Grosso do Sul and whose feeding preference of P. xylostella larvae of 3rd instar. We intend to answer the following questions: (1) Are the plant species analyzed fagodeterrentes? (2) what type of extract produces the least food preferrence? To answer these questions, we treated cabbage disks with aqueous extracts stored in a refrigerator in periods of 0, 7, 14 and 21 days and the methanolic extracts were treated at concentrations of 0.5 mg/mL, 1.0 mg/ mL, 2.0mg/mL. The aqueous and methanolic extracts of T. silvatica presented the lowest values of feeding preference, 0.113 and 0.06, respectively, compared to other extracts.
