Effects of botanical insecticides on the instantaneous population growth rate of Aphis gossypii Glover (Hemiptera: Aphididae) in cotton

Abstract

ABSTRACT. Botanical insecticides have been studied aiming the alternative pest control. The present study investigated the effects of these insecticides on the instantaneous population growth rate (ri) of Aphis gossypii. Botanical insecticides were tested in the following concentrations: Compostonat Palavras-chave: pulgão-do-algodoeiro, bioatividade, Gossypium hirsutum, inseticidas naturais.

Compatibility of Beauveria bassiana and alternative phytosanitary products

“…The products tested have a proven insecticidal potential (de Andrade et al . ), as well as the components of their formula (Alecio et al . ; Lynn et al .…”

“…For this, the average values of percentage of sporulation, vegetative growth and conidia germination were used. The products tested have a proven insecticidal potential (de Andrade et al 2012), as well as the components of their formula (Alecio et al 2010;Lynn et al 2010;Zorzetti et al 2012;Ekeh et al 2013). In addition, B. bassiana is also pathogenic to a range of insects (Allah et al 2015;Toledo et al 2017;Wraight and Ramos 2017;Yuan et al 2017).…”

Multigenerational exposure of populations of Oppia nitens to zinc under pulse and continuous exposure scenarios

“…There is a need to use parameters that may represent pollutant effects on populations. When the performance of pesticides on pests is evaluated, the instantaneous population growth rate consistently predicts deleterious effects of pesticides on pests better than other techniques (Andrade et al 2012). When the performance of pesticides on pests is evaluated, the instantaneous population growth rate consistently predicts deleterious effects of pesticides on pests better than other techniques (Andrade et al 2012).…”

“…One of the parameters that can be used effectively is the instantaneous population growth rate (PGR; r), which integrates survival and reproduction to measure the population growth rate (Stark and Banks 2000;Herbert et al 2004). When the performance of pesticides on pests is evaluated, the instantaneous population growth rate consistently predicts deleterious effects of pesticides on pests better than other techniques (Andrade et al 2012). Thus, we also used instantaneous population growth rate in the form of a niche width to evaluate pulsed and continuous metal exposure.…”

Insecticidal and Repellent Action of Pogostone AgainstMyzus persicae(Hemiptera: Aphididae)

“…Plant-derived extracts (phytochemicals) and bio-agents represent an alternative to synthetic pesticides and could reduce these harmful effects (Goh et al 2001;Kim & Kim 2008). In recent years, researchers have increasingly focused on the use of natural products obtained from plants to control insect pests (Andrade et al 2012;Ebrahimi et al 2013;Pinto et al 2013).…”
