Nicotine gave better results than arsenicals against the black- 
head fireworm ( Rhopobota ( Eudemis ) vacciniana ) on cranberries. A 
spreader, such as soap or glue, is necessary.

The nymphs of the froghopper ( Si as t opt era v ittata Ball) can be 
controlled by spraying with one part of Black Leaf 40 to 400 parts of 
water with 2 lb. resin fish oil soap to 50 gal.; or 800 parts of water 
when the nymphs are very small. Spra:/s of Black Leaf 40 (l;400) killed 
gypsy moth caterpillars ( Porthetri a dispar L. ) in their early stages 
but not when they were nearly full-grown. The same spray is effective 
against the black-headed fireworm ( Rhopobota vacciniana Pack.) as well 
as the spittle insect.

Satisfactory results against the blackhead fireworm ( Rhopobota 
vacciniana ) on cranberries were obtained from three applications of 
nicotine sulphate (40-percent) at 1 to 800 plus 2 lb. fish-oil soap 
per 50 gal. of spray. Fcr tobacco thrips ( Franklinie lla fusca ) 14 oz. 
nicotine sulphate plus 3 lb. soap to 50 gal. water has proved a success- 
ful spray if applied properly once a week during the emergency period.

Winter-flooded bogs should be sprayed ence, a few days before 
the blossoms are out with 1 gal. Black Leaf 40 in 400 gal. water with 
16 lb. fish oil soap. This treatment largely takes the place of June 
reflooding in reducing the numbers of Rhopobota naev ana Hb. (vacci nian a 
Pack.) (the blackhead fireworm); Clastoptera vittata Ball. (the spittle 
insect); Crambus hortuellus (the cranberry girdler) ; leafhoppers ( Suscclis) 
and springtails ( Collembola ) .
