.-22- 
since last August in our cages now. Most cotton has been 
picked once and some cotton several times, but even on the 
bushes with green leaves along irrigation ditches there are no 
leaf worms. 
COTTON STAINSB ( Dysdercus suturellus H. Sch. ) 
Haiti R. <£# Smith (January 8): The cotton stainer began tc cluster 
on the bolls about the midj.le of December at port-au-Frince. 
They have been so abundant during the last two seeks that con- 
trol efforts have been necessary. The bugs are picked or jarrei 
into pans of kerosene. The very large numbers of nymphs attack- 
ing fallen bolls have been readily controlled with cyanogas. 
Considerable stained cotton occurs in early pickings. 
(February 22): There are, however, large numbers of cottcn 
stainers feeding primarily on the young bolls. This is the 
second generation of adults since last December and there are 
a good many third-generation nymphs in evidence. 
SOUTHER!! GREEN STINK BUG- ( iTezara viridula L. ) 
Haiti R, G* Smith (January .9 ) : A common pest in Haiti and attacking 
many plants. It was particularly abundant on cotton on the 
young bolls a few weeks ago at Damien and it is thought that 
their attack is a common cause of the dropping of bolls in the 
early stage of gro-th. Peas and tomatoes are also being attacked 
by this insect. 
RED SPIDER ( Tetranychus tslarius L, ) 
Haiti R. C» Smith (January 8): Many plants 3.x s severely attacked 
by these mites at Port-au-Prince. A study is being made to 
find whether their distribution is correlated "ith the presence 
or absence of leaf pubescence. (February 22): The cotton leaf 
nite is now very abundant indeed in our experimental cotton. 
This is young cotton and not yet producing bolls. 
TOBaCCO 
HORN "OEMS ( Protoparce spp. ) 
Haiti R. c. Smith (January 9): These worms have killed some plants 
and more or less completely d efoliated others on the horticultur- 
al farm at Damien. They appear to be at their peak also on 
tobacco. A plantation at La Serre reported them to have been 
more troublesome lately. Tomatoes are also being attacked by 
these worms. (February 22): The horn worms are giving consider- 
able trouble to tobacco, judged by the number of calls for 
lead arsenate.
