 This is not a serious pest and remedial 

 measures seem unnecessary.

 General Appearance 

 The adults are very small grayish- 

 brown bugs, about one-eighth of an inch 

 long. The young are somewhat lighter in 

 color, having reddish-brown abdomens 

 and lacking wings. The legs and anten- 

 nae appear very long and are dark. 



Life History 



The eggs are deposited in the siirin.s; 

 and early summer by the adults which 

 have hibernated. The young are dull gray 

 or brownish-red, and collect in great num- 

 bers upon the host plants. The life cycle 

 is short, there being many successive 

 broods during the year. 



Distribution 



Throughout California. A roninioii 

 plant pest. 



Food Plants 

 Besides strawberries, grapevines, let- 

 tuce, potatoes, apple foliage, the cruci- 

 ferae. 



Control 



As this bug breeds largely upon wilil 

 plants, such as mustard, radish, purslane, 

 etc., clean culture should be practiced to 

 eliminate these food plants. 



Soap emulsions and tobacco sprays are 



excellent remedies. Pyrethrum is also 



recommended, but is too expensive for 



large plantings.

 (General ,\i)pearaiiee 

 The adults vary from a gray to a very 

 dark brown in color and from three- 

 eights to one-half an inch in length. The 

 eggs are pale yellow and laid in rows. 

 The larvae are milky white and with- 

 out legs. The pupae are also white. 



Life History 



The eggs are laid in secluded places 

 close to the ground. The young white 

 grubs live under ground, doing great 

 damage to the roots of many plants. The 

 adults when seen during the day are very 

 sluggish. Tliey have no power of flight. 

 The damage done is usually unknown ow- 

 ing to the fact that the larvae work under 

 ground and at night. 



Distribution 



California, eastward. 



Food Plants 



Strawberry roots. 



Control 



The larvae, like all subterranean pests, 

 are difficult to control, but thorough cul- 

 tivation and hoeing close to the plants 

 are great aids. In light sandy soil, car- 

 bon bisulfid is efficient. The adults being 

 unable to fly are easily kept from trees 

 by a cotton or tanglefoot band around 

 the trunk.

Grain or Stran))erry Thrips 



EutUrips tritici Fitch. 

 Very minute. The color is yellow with 

 orange colored thorax. 



Life History 



The eggs are very minute, globular in 

 shape and red in color. They are insert- 

 ed within the tissues of the host and 

 hatch in a few days. The nymphs or 

 young greatly resemble the adults, and 

 begin to feed at once. The principal 

 damage is done to the blossoms. The 

 strawberry especially suffers, the pistil 

 being the portion of the bloom destroyed. 

 The winter is probably spent in the soil 

 as in the case of the pear thrips. 



Distril)uiion 

 General. 



Control 



Seldom destructive enough to warrant 

 control, when necessary the sprays for 

 pear thrips (except whitewash) are effect- 

 ive in controlling this pest.
