While this method may be useful inthe small garden, it is not adapted for use on a large control of the tarnished plant-bug in the nursery, onasters when grown for seed and in commercial strawberry fieldsis still an unsolved Fig. 331.—Egg of the tarnished plant-buginserted near the tip of a poach nursery tree;the terminal bud has been killed by the feedingpunctures of the bugs.

In Florida a small dark brown sucking bug with light-coloredwings and brownish legs, Pamera vincta Say, attacks straw-berries, sucks out the contents of the ovaries and causes abuttoning of the fruit like that produced by the tarnishedplant-bug. A similar injury is caused by the leaf-footed plant-bug (Leptoglossus phyllopus Linnaeus). Satisfactory methodsof controlling these insects have not been worked out, but thesuggestions given above for fighting the tarnished plant-bugmay be found of value. Reference Fla. Agr. Exp. Sta.
