Antonio Berlese: Architect of Applied Entomology

🔬 Focus on Pest Insects

Antonio Berlese (1863–1927) was a distinguished Italian entomologist whose career was largely dedicated to the study of pest insects, particularly those affecting fruit trees. His meticulous research provided foundational knowledge for understanding and managing agricultural pests.

📚 Prolific Author and Publisher

Berlese's scholarly output was immense, comprising over 300 articles. He authored the comprehensive two-volume work, Gli insetti loro organizzazione, sviluppo, abitudini e rapporti con l'uomo (1909 and 1925). He also produced the extensive series Acari, Myriapoda et Scorpiones hucusque in Italie reperta, which appeared in 101 installments between 1882 and 1903, featuring over a thousand illustrations drawn by Berlese himself.

🌿 Specialization and Collaboration

He was a recognized specialist in Hemiptera, particularly the Coccoidea (scale insects). In collaboration with Gustavo Leonardi, he issued the Chermotheca Italica exsiccata series (1895–1909). Berlese also offered the microscopic slide series Acarotheca Italica for sale, making his detailed observations accessible to the scientific community.

🏛️ Leadership in Agricultural Science

In partnership with his brother, Augusto Napoleone Berlese, he co-founded the Revista di Patologia vegetale in 1892. Berlese's leadership extended to directing the Istituto Sperimentale per la Zoologia Agraria starting in 1899. In 1903, he established the influential review Redia, which he edited until his death. This publication championed zoological studies in agriculture, forestry, and urban environments, with a strong emphasis on entomology, acarology, and nematology, aiming to enhance taxonomic knowledge of pest species.

🧫 Extraction Apparatus

In 1905, Berlese described a significant apparatus for scientific study: the Berlese funnel. This device is designed to extract small arthropods and other invertebrates from soil and litter samples. It typically uses a heat source (like a light bulb) to drive the organisms downwards through a sieve into a collecting fluid, such as ethanol.

While variations and improvements have been developed over time (such as the Tullgren funnel), the fundamental principle described by Berlese remains a standard technique in ecological and soil biology research for collecting specimens for examination and identification.
