In Florida a small dark l^rown sucking bug with light-colored 

 wings and brownish legs, Pamera vincta Say, attacks straw- 

 berries, sucks out the contents of the ovaries and causes a 

 buttoning of the fruit Uke that produced by the tarnished 

 plant-bug. A similar injury is caused by the leaf -footed plant- 

 bug {Leptoglossus phyllopus Linnaeus). Satisfactory methods 

 of controUing these insects have not been worked out, but the 

 suggestions given above for fighting the tarnished plant-bug 

 may be found of value.

The Strawberry Thrips 

 Euthrips tritici Fitch 



This is the commonest and most widely distributed species 

 of thrips in this country and occurs abundantly in the flowers 

 of almost any wild or cultivated plant. Destructive outbreaks 

 in strawberry fields have been reported from lUinois and 

 Florida. 



The adult thrips is a slender insect about ^o inch in length, 

 usually brownish-yellow in color, although very variable in this 

 respect, and is provided with two pairs of narrow wings mar- 

 gined with a row of long hairs ; the immature stages closely 

 resemble the adult in general form, but are wingless and are 

 of a lighter or clearer yellow color. 



The thrips appear on the strawberry plants in early spring, and 

 as soon as the buds open are found in the flowers. Their mouth 

 parts are intermediate between the sucking and biting types.
