Description

General description

Pyrrole is one of the flavor compounds that is formed in thermally processed foods due to the Maillard reaction.

Application

<ul>
<li><strong>Can neonicotinoid and pyrrole insecticides manage malaria vector resistance in high pyrethroid resistance areas in Côte d′Ivoire</strong>: This research evaluates the effectiveness of pyrrole insecticides in controlling malaria vectors in regions with high pyrethroid resistance. The findings suggest that these insecticides can play a significant role in integrated vector management strategies to combat malaria (Ekra et al., 2024).</li>
