HaaiOf P, S. Oman, August 2, 1955 -3, 
A short time was spent la Paris with Br. Marc Andre, Assistuit Urector of the 
Matnral History Musetaa, He is one of the two French acarologlsts but is doing 
little research now because of adainistrstive duties* 
A stopover was made in liondon on th® return trip to aeet or. June Collyer and 
Mr, Chant vim are working on the spider siite-predstojT’ adte problea in Kent* 
Also, I net th® *rs, Hughes (Mr, end Mrs.) wh© ere working on *lte physiology 
and on th© sites affecting stored food products. 
The opportunity to meet these workers was invaluable. The picture of mites in 
the tropics as indicated without microscopic stud^ is a little surprising in 
that few eric^r^ids or spider aites were found in the hot regions and when 
fomd were not causing any noticeable daaage. (In California, Keifer has 
found about 200 species of Erlophyidael), As yet species have not been iden* 
tified and no guess can be made as to whetiier these f oimd are imdescribed ot* 
are world vide in distribution; aauy a;^oar to be undoscribod genera. All 
■types of plants were attacked— i’roa tropicul forms to peach tree8>-aad poten- 
tially, many of the mtes may be of some concern to our own agriculture*
