The Asparagus Miner

(Agromyza simplex) In a recent bulletin from the New York Experiment Station, Prof. F. A. Sirrine describes a comparatively new and injurious insect on asparagus. It was discovered on Long Island, and injures the young plants by mining just underneath the outside surface. The

habits of this creature are such that there is little chance of applying remedies for its destruction. Cultural and preventive measures seem to be the most practical, and are suggested. The parent insect is a small fly, which deposits its eggs for the first brood early in June, and no doubt much can be done toward keeping the pest under control by not allowing small shoots to grow during the cutting season. Professor Sirrine is of the opinion that where young beds are put out yearly the pest can be kept in check by pulling and burning the old stalks. He points out the fact that the stalk should be pulled in the fall rather than in the spring, as it is difficult to pull them early in the season, and in many cases the dormant stage of the insect is left in the ground.
