The third instar of the host is preferred for parasitization by this 
species. In general) releases this year were delayed somewhat beyond the 
release date optimum for the season. The average optimum 7-day period 
(or the average 7-day period after the firf?t host larvae pass into the third 
instar) for release of this species was found to be June 23-29 in the two- 
gene ration area (data from New England), and July 19-25 in the one-genera- 
tion area (data from Ohio), The actual synchronization obtained this 
season, is shown in charts 1 to U, inclusive. These charts show that 85 
percent of the releases in the Middle West and those in Connecticut were 
made after the period of maximum host abundance had passed, but, that in 
northwestern New York and in New Jersey the parasites were in the field 
before the peak of the preferred instar. However, in all cases, except 
the release in Albany County, N. Y. , the liberated adults should have found 
favorable host instars present in the field at the time of their release. 
2. Lyde 1 la stabulans var. grisescens R. D. (Tachinidae): 
A total of 92,922 adults of this species were released in Ul colonies, 
39 of these being dispersion colonies. One test colony of this species was 
started in Atlantic Township, Monmouth County, N, J,, and one in Lee Township, 
Accomac County, Va. Table U summarizes the releases of this species and 
map 2 shows the extent of colonization prior to 1935 an & the localities that 
received releases during that season.
