STRAWBERRY PESTS 



White grubs ^^ (Phyllophaga sp.) 

 Order — Coleoptera 



White grubs are the larvae of May beetles or 

 ''June bugs"; there are at least eight species of 

 these that are injurious; these insects have a pro- 

 longed life cycle, two to three years and may be 

 longer in some cases; w^hite grubs are liable to 

 accumulate in old pastures and meadows and w^hen 

 these are broken and other crops put on the sod 

 there is liable to be much injury; the grubs eat off 

 roots of strawberry plants. 



The eggs are laid in balls of earth in the ground 

 where they hatch and the grubs live there until the 

 summer of the second year when they change to 

 pupae in the soil ; the pupae change to beetles in late 

 summer but the beetles remain in their earthen cells 

 until the following spring. 



Control — Do not follow sod land with straw- 

 berries; put some other crop between; in gardens 

 and small plantings dig grubs out by hand.
