Brazilian Spin-Out Validates “Nanofly” Bio-Pesticide Achieving 95% Efficacy Against Horn Flies in Cattle

CAMPO GRANDE, Brazil — October 14, 2026 — Nanofly, a biotechnology spin-out from the Federal University of Mato Grosso do Sul (UFMS), has published laboratory trial results demonstrating 95% mortality against horn flies (Haematobia irritans) using a proprietary botanical nano-encapsulation platform. Horn flies represent one of the most economically destructive ectoparasites in global beef and dairy production, inflicting billions of dollars in annual losses through blood-feeding stress, reduced daily weight gains, and lower milk yields.

Overcoming Synthetic Chemical Resistance

Traditional chemical sprays and ear tags relying on synthetic pyrethroids and organophosphates face widespread parasite resistance across Latin America and North America.

1. Sustained Release: The polymeric matrix protects volatile botanical active compounds from rapid solar degradation, allowing extended residual action on the animal’s coat.

2. Residue-Free Production: Because the formulation contains no synthetic organochemicals, milk withdrawal periods are eliminated, offering immediate value to pasture-based commercial dairies.
