The effects of Annonaceae and Amaryllidaceae extracts in controlling the Thrips tabaci Lindeman (Thysanoptera: Thripidae)

Abstract: The objective of the present study was to evaluate the effects of Annona muricata and Allium fistulosum extracts in controlling Thrips tabaci and to identify the main secondary metabolites. We obtained extracts from A. muricata seeds and of A. fistulosum L. leaves. An in vitro model for evaluating insecticide against T. tabaci was performed. The effect of the extracts was individually and subsequently assessed in mixtures for determining the mean lethal concentration. According to the results obtained with T. … Show more

“…It is necessary to emphasise the importance of education to farmers for the proper use of pesticides, in terms of the choice of product and the correct dosage to avoid contamination of the products which are marketed. Investigations from Giraldo et al, (2020) in the region of Risaralda, Colombia stand out, from where natural extracts have been used to fight the onion pests as an alternative to synthetic pesticides, for example against T. tabaci, the A. muricata L. extract showed LC 50 = 82.93 mg L -1 , the onion essential oil showed LC 50 = 335.29 mg L-1 , and the onion hydrolate showed LC 50 = 2348.84 mg L -1 . The combinations of extracts reached mortality rates between 50% and 72.62%, which are promising results as alternatives for the comprehensive management of the onion pests.…”
