INSECT CONDITIONS . IN PUERTO RICO 
By G. N. Wolcott 
Insular Experiment -Station, Rio Piedras 
The past spring and summer in the more humid part of Puerto Rico has been 
unusually dry, and the autumnal rains have' been less than normal. The chinch 
bug ( Blissus leucopterus Say) was noted in considerable abundance on the upper 
leaves of young sugarcane plants at Rio Grande and Canovanas a few days ago, 
something I have never seen before. 
An outbreak of the pyralid caterpillar, Pyrausta cerata F. ( -Epicorsia 
mellinalis Hbn. ) on the leaves of the pendula tree," Citharexylum fruticosum , 
has recently been noted at Humacao, Maunabo, and Arroyo, in the southeastern 
corner of the island, and also at Bayamon, Cayey, and Caguas in the interior, 
and at Isabela and Aguadilla in the northwestern corner, presumably being 
general wherever the host tree is present. 
INSECT CONDITIONS IN GUM — JULY AND AUGUST 1957 
By R. G. Oakley 
' ' ■ ■•• Agana, Guam 
The attacks of the melonfly ( Bactrocera cucurbitae Coq. ) probably of 
recent introduction into Guam, were general in most community centers and in 
a few isolated cucurbit fields during July. Infestations reached as high as 
100 percent in some cases. The prevalence of wild papayas over the island and 
a local cultivation practice of often abandoning cucurbit fields to weedy 
growth and the development of small melons after the commercial crop is picked, 
is very favorable to the development of a large population. 
The bean leaf roller ( Lamprosema diemenali s Guen. ) was very abundant on 
string beans and as a minor pest on other legumes in July. It was not uncommon 
to find 50 percent of the leaf surface of string beans infested. (Det. by 0. 
H. Swezey. ) .... 
A squash bug, Leptoglossus membranaceus F. , commonly infesting a number 
of hosts, v/as doing considerable damage to cucurbits and string beans in July 
and August. In one field dozens of bursted watermelons were completely covered
