Japanese beetles ( Popilli a japonic a Newm. , Coleootera, Scarabaeidae) 
on various trees, shrubs and flowers were fairly well controlled. The spray 
acts as a repellent. The effective period is 6 to 7 days. Satisfactory 
repellency can be obtained by spraying 6 or 7 days apart. 
Asiatic garden beetles ( Autoserica castanea . Arrow, Coleoptera, 
Scarabaeidae) on various flowers were fairly well controlled. The spray 
acts as a repellent. The effective period was 4 to 5 days. Control is not 
as good as for Japanese beetle. 
June bugs ( Lachno sterna, spp. = Phyllophaga spp. , Coleoptera, 
Scarabaeidae) were fairly well controlled. The spray acts as a repellent. 
The effective period was 6 days. Feeding is checked for 6 or 7 days. 
Rose leaf beetles (Nodonata puncticollis Say, Coleoptera, Chrysomelidae 
on bush honeysuckle were 60 percent controlled. The spray acts as a repel- 
lent. The effective period is 4 to 6 days. Repeated sprays should give 
satisfactory control. 
Willow leaf beetles ( Lina spp. = Chrysomela spp. , Coleoptera, 
Chrysomelidae) on black willow trees were well controlled. The spray acts 
as a repellent and contact poison. There is good control of larvae. 
Mexican bean beetles ( Epilachna v arivestis Muls. (=corrupta Muls.) 
Coleoptera, Coccinellidae) on beans were satisfactorily controlled. The 
spray acts as a contact poison and as a repellent. The effective period is 
8 days. Eighty percent kill of larvae, 20 percent repellency on beetles. 
Repeated sprayings would give good control. 
Striped cucumber beetles ( Diabrotica vitfrata F. , Coleoptera, 
Chrysomelidae) on cucumbers were controlled 100 percent. The spray acts 
as a contact poison or as a repellent. The- effective period was 2 weeks. 
No beetles were observed after more than 2 weeks after spraying. 
Woolly aphids (various species of Homoptera, Aphididae) on beech, 
elm, larch, and white pine trees were, not satisfactorily controlled. Very 
little kill by contact against any of the woolly aphids. 
Aphids (species of Homoptera, Aphididae) on roses and white pine 
trees were satisfactorily controlled. The spray acts as a contact poison. 
Good kill on roses, poor on pine. 
Lace bugs ( Gory tfruca arcuata Say, Hemiptera, Tingida.e) on Sycamore, 
azaleas, and asters were satisfactorily killed in three out of four tests 
made. The spray acts as a contact poison. There was 90 to 100 percent kill. 
Euonymous scale ( Chionaspis euonymi Comst. , Hemiptera, Coccidae) 
on euonymus trees was controlled satisfactorily. The spray acts as a 
contact poison. Control was satisfactory against young scales.
