“…Considerando a viabilidade de compostos bioativos obtidos de plantas para o controle de pragas de grãos armazenados, a repelência/deterrência do pó de N. tabacum (Tabela 2) associa-se aos alcaloides naturais (nicotina), que devido a rápida ação neurotóxica, principalmente por contato (MORAIS et al, 2016), levando-o à morte (SILVA et al, 2017), ou imobiliza sua atuação de (DOGAN et al, 2017), mantendo tecidos vegetais sem alterações deletérias (ARAÚJO et al, 2018;VENDRAMIM, 2017;RIBEIRO et al, 2016a). No campo, extrato aquoso do pó de tabaco (10% (p v -1 ) apresentou eficácia similar a um inseticida sintético à base de deltametrina no controle de insetos-praga de cultivos hortícolas (RIBEIRO et al, 2016b).…”

Plants with insecticidal effect are among the alternatives as a tool to control the insect-pest of stored grains. The objective of this study was to characterize the efficiency of plant-based powders on Sitophiluszeamaisinsects in stored grains. Usingfourteenplant species (Arnica montana Baccharistrimera,Coriandrum sativum,Coffea arabica,Cymbopogon martini,Helianthus annuus, Lippia gracillis,Mentha pulegium,Moringa oleífera,Nicotiana tabacum,Piper aduncum, Piper hispidinervum,Sesamum indicumandVitis labrusca)obtained from tritured vegetable material, and compared with a control treatment. The experiment carried out in a completely randomized design, with six replicates each treatment. In the tests, 0.5 g of the inert powders mixed into the grains (50 g) of hybrid corn AS 1551 into plastic vials and infested with 10emerged adultofS. zeamais. After 20 days of infestation, oviposition evaluated and counts of emerged adults. At the end of the infestation period, evaluated the dry weight of the insects, the weight of grains consumed and the period of development (egg-adult). Most of the vegetal powders presented effective action on the emerged insects. By the use of the powders,it verified reduction in the ooposition, except for Vitis labruscaand Sesamum indicumwhose egg numbers were higher than control, also had less effect on the development of caruncho larvae. The low weight of adults from corn kernels treated with Nicotiana tabacumpowder is relatedreduction in feeding of S. zeamaislarvae.

Acetogenin-Based Formulated Bioinsecticides on Anastrepha fraterculus: Toxicity and Potential Use in Insecticidal Toxic Baits

et al. 2020

The present study evaluated the lethal toxicity and oviposition deterrence of ethanolic extracts of Annona mucosa Jacq., Annona muricata L., and Annona sylvatica A. St.-Hil on Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae) compared with those of a limonoid-based bioinsecticide (Azamax™ 1.2 EC-azadiractin +3-tigloyl-azadiractol) and a synthetic spinosyn-based insecticide (Delegate™ 250 WG-spinetoram). In addition, the efficacy of the selected toxic bait formulations was evaluated by mixing them with food attractants (Anamed™, 3% Biofruit and 7% sugarcane molasses). In the topical application and ingestion bioassays (2000 mg L −1 ), the aqueous emulsion of the A. mucosa extract caused greater than 80% mortality of A. fraterculus adults in a similar manner to the spinosyn-based synthetic insecticide. Concentration-response curves were performed for the most promising treatments and showed an activity level dependent on the mode of contamination, exposure time, and applied concentration. In bioassays with and without choice, the A. mucosa (77%), A. muricata (51%), A. sylvatica (60%), Azamax™ (74%), and Delegate™ 250 WG (100%) significantly reduced the number of punctures and galleries in grape berries. In combination with the food attractants Anamed™, 3% Biofruit, and 7% sugarcane molasses, the emulsion of the A. mucosa extract had a residual effect similar to that of the spinetoram insecticide, with a mortality rate of over 80% of A. fraterculus adults up to 14 days after application (DAA) in the absence of rain. Thus, acetogenin-rich formulations, especially from A. mucosa seeds, are useful alternatives for the integrated management of A. fraterculus in agricultural orchards.

Duponchelia fovealis (Zeller, 1847) is a new pest of strawberry crops worldwide. To develop alternative strategies for its management, we assessed the lethal toxicity and growth inhibitory action of formulations prepared from ethanolic seed extracts of pre-selected species of Annona (Annona mucosa Jacq., Annona muricata L., and Annona sylvatica A. St.-Hil.), which were previously characterized by their high content of annonaceous acetogenins. In addition, the extracts were compared to a limonoid-based bioinsecticide [Azamax® 1.2 EC (azadirachtin + 3-tigloil-azadiractol), positive control] on D. fovealis larvae. Aqueous emulsions prepared from ethanolic seed extracts of A. mucosa and A. sylvatica and a limonoid-based bioinsecticide had low lethal toxicity to D. fovealis larvae; nevertheless, they caused a pronounced inhibition of their larval development. Thus, the combined effects of lethal and sublethal toxicity of acetogenin-rich formulations and the limonoid-based commercial bioinsecticide may offer a route to new control strategies of D. fovealis in strawberry crops, especially in organic-based production systems.
