Maine Agricultural Experiment Station. 1917. 



first issuance of the larvae from the fruit must be determined. 

 In 1895, Harvey (1895, p. 116) writes, "the larvae began to 

 emerge on June 20." In 1915, the first larvae issued on June 

 30, but in all probability, the dates would vary in different sea- 

 sons. We began to pick drops on June 14, 1914, and June 13, 

 1915, and continued to gather the fallen fruit at least twice a 

 week until the crop was harvested. The results obtained by the 

 destruction of fallen infested fruit are discussed under methods 

 of control. 



Cracked fruit. — From the same bush a record was obtained 

 of the number of e.gg chambers in each gooseberry drop and the 

 number of fallen cracked fruit with or without egg cavities. 

 The results are indicated in table 6.
