SPECIES OF WOOD-BORING INSECTS 



Abstract. — Small numbers of 10 species of wood-boring insects were 

 reared from newly hatched larvae to adults on artificial media with good 

 survival. Species with life cycles of up to 2 years in nature were reared 

 on the media in less than 1 year. Although all of the adults appeared 

 - normal physically, some were sterile. One species was reared artificially 

 for three generations. Survival figures and the developmental periods of 

 the larval stages are given.

Lack of suitable rearing techniques has hampered research on the 

 biology and control of many species of wood-boring insects injurious to 

 forest and shade trees. This is especially true for those species with ex- 

 tended life cycles that appear as adults only briefly in the field annually, 

 biannually, or less often. 



Recent work has shown that some wood-boring insects can be continu- 

 ously reared artificially. Wollerman, Adams, and Heaton (1969) reared 

 the locust borer, Megacyllene robiniae (Forster), continuously on artifi- 

 cial media for several generations. Smith (1965) reported rearing the 

 peach tree borer, Sanninoidea exitiosa (Say), on immature apples. Solo- 



^ mon {1966) was able to successfully rear the carpenterworm, Prionoxys- 



tus robiniae (Peck), on artificial media; and Harley and Willson (1968)
