bacteria. That small number of Insects would not change the overall balance In 
the area between frost-sensitive and frost-tol erant Insects. Fields treated 
conventionally In agriculture with bactericides, pruned, or other agronomic 
practices that reduce INA + bacterial populations would be expected to affect 
Insect populations If there was any causal relationship. No such observations 
have been reported in the world literature. 
5.3.6 Animal Populations 
The modified INA" bacteria to be used in the experiment will not differ 
from their counterparts that already exist in nature. There are no known cases 
of either £. s_. syrinqae or Erwin ia herb i col a , isolated from plants, having any 
effect on animals. Wild-type strains of both bacteria have been sprayed on 
test plots by Drs. lindow and Paropoulos over several years and by others over 
a period of 20 years with no adverse effects on animals or humans. P_. s_. 
syringae does not survive at mammalian body temperatures and has no known 
pathogenicity to cold-blooded animals. _E. herblcol a Isolated from plants, as 
Is the case for the proposed field test, have no known pathogenicity to 
animals. (U) Accordingly, the proposed experiment will have no significant 
effect on animals or humans. 
5.3.7 Atmosphere and Climate 
Recent work has shown that significant numbers of leaf-surface bacteria, 
including species of ice-nucl eation-active bacteria, can enter the atmosphere 
as aerosols (Llndemann et a 1 . , 1979, 1981; Vennette and Kennedy, 1975). The 
settling rate of these small aerosolized bacteria In the atmosphere was shown
