Acaricidal activity of small molecule antagonists of the tick kinin receptor against Rhipicephalus microplus acaricide‐susceptible and resistant strains

Pest Management Science, Volume 82, Issue 2, Page 1618-1628, February 2026.
Two small molecules, SACC‐0039590 and SACC‐0428788, killed cattle fever tick, R. microplus, susceptible Deutch strain and pyrethroid resistant Arauquita strain larvae. SACC‐0039590 at 1 mM decreased the reproductive parameters of Deutch females. Abstract BACKGROUND Resistance to acaricides underscores the need for tick control alternatives.

Ensuring Pollinator Presence in Expanding Oil Crops: The Case of Mystrops debilis (Nitidulidae) and the Macauba Palm (Acrocomia aculeata, Arecaceae)

Journal of Applied Entomology, Volume 149, Issue 8, Page 1180-1195, September 2025.
ABSTRACT The macauba palm (Acrocomia aculeata, Arecaceae) is a Neotropical native oil palm, increasingly important in Central and South America due to rising demand for raw materials and its potential for bioenergy. Understanding its pollinator ecology is crucial to identify new areas for cultivation. This study examines the structure of floral visitor
