Synopsis

Forage crop insects in Massachusetts in 1961 come alive with detailed population data and practical notes for growers and observers.

This report summarizes a year of field surveys across Massachusetts, focusing on key pests such as aphids, leafhoppers, plant bugs, and alfalfa weevils. It highlights seasonal patterns, relative abundances, and the kinds of field observations that help shape control decisions, including weekly sampling in the Amherst area and 100-sweep methods used to track insect presence.

• Learn which insects dominated in 1961, including potato leafhopper and pea aphid, and how their numbers affected alfalfa and other forage crops.
• See patterns of abundance across weeks and counties, with notes on peaks in late spring and late summer.
• Understand common predator presence and how it related to pest populations that year.
• Get a glimpse of field sampling practices and how researchers interpreted population trends to guide treatment decisions.

Ideal for readers of state survey reports, extension agents, and growers seeking a concise view of past insect activity and its implications for forage crop management.
