Evaluation of insecticidal effects of Tabernaemontana catharinensis A.DC. (Apocynaceae) and Zeyheria montana Mart. (Bignoniaceae) extracts against the fly Zaprionus indianus (Díptera: Drosophilidae) (Gupta, 1970)

Zaprionus indianus (Díptera: Drosophilidae) (Gupta, 1970) is considered a potential pest-fly of commercial fruits in Brazil, particularly for cultivars of figs, star fruits and persimmons in the southeast area. Considering the need of new alternatives for Z. indianus control, the aim of this work was to evaluate the insecticidal activity of ethanol extracts from Tabernaemontana catharinensis A.DC. (Apocynaceae: Tabernaemontana) stem bark and Zeyheria montana Mart. (Bignoniaceae: Zeyheria) leaves against different development stages of Z. indianus. Overall results showed that these extracts did not affect this fly in the adult stage, neither considering the total number of survivors when compared to control group or survival ratio by sex. However, they were effective in inhibiting the emergence of imagoes of Z. indianus, which could be of relevance for the control of this harmful fruit fly.Downloads
