' ississipt ii. C. Lyle and assistants (March. -35.) : Heavy infestation of 
red slider on lilies' in a greelihouse at Moss Point was observed on 
March 17. The pest., is fairly abundant on arborvltae in Lincoln and 
Pike Counties and. is present on Cane Ilia ,ia;oonica -at Fonlarville 
and Picayune. A rather heavy infestation vp.s noticed -in a satsuna 
orchard in Harrison County on March 14'." 
Louisiana. B. A. Osterberrer (March 21): ; The common red slider, is . 
nunerous on azalea and arborvitae. 
Missouri. L. Ha.seman (jSHarch 24) J The red spider was a very, serious 
rest in a number of central- and no rthwe stern-Missouri orchards 
and a few southwest era- Missouri orchards during the dry July of 1935. 
Unbelievable, numbers went into resting o v r hibernating conditions in 
the soil, in. the .litter,, arid; under ;the bar]: scales on th#*:t t rees- in 
these 'orchards;"; but before winter .set in, rrpctica^lly all in the soil 
were dea'd and 'in midwinter tiost of those" in .leaf coverage and in the 
crotches of trees were also dead. Considerable numbers, however, 
survived under the bar 1 .:-- scales and freezing experiments conducted

General. P. h T . Annand (''arch 11): Preliminary' reports on mortality of 
chinch bugs in' the seriously invested area of the Corn Belt States 
indicate that average mortalities as high as -50 percent occur in. 
certain counties in Iowa, Illinois, and' Indiana* Mortality is 
considerably lover in Missouri, 3Cansas, .and. Oklahoma. liven with the 
mortality indicated at present, there are sufficient bugs to cause 
serious damage should spring weather be favorable. 
Indiana. C. Benton (March 20): 'The finding of forty additional samples 
of bunch grasses in Tippecanoe County. on February 27 and March 16 
substantiates last month's report of about 50 percent mortality of 
hibernating chinch bugs. 
Illinois. "7, F. Plint (March 20): Recent general surveys of the chinch 
bug infested area have shown that the bugs came through the winter 
with mortality of approximately 22 to 25 percent. Our examinations 
to date indicate that there are about 80 percent as many bugs now in 
hibernation as there were in the spring oi 1934, There are enough 
bugs to cause serious damage should the weather of the late spring- 
be dry. 
Correction. — Chinch bug mortality in Indiana as reported in the Insect Pest 
Survey Bulletin dated March 1, 1936, p. 5, should read "from 19 to 98 percent.
