INSECT CONDITIONS IN PUERTO RICO DURING AUGUST, 1S32 
G. N. W (rlcott 
Insular Experiment Station, Rio Piedras, Puerto Rico 
A survey of the status of the cottony cushion scale, I eery a purchasi Mask., 
conducted during the middle of August shows that it is now less abundant in 
citrus groves than at any time since its discovery, and difficulty is experienc- 
ed in finding suitable localities for the liberation of lady-beetles. 
Every caterpillar collected from nearly 3,000 pods of lima beans maturing 
during June and July at Isabela was Etiella zinckenel. la Treit. They averaged 
37 caterpillars per 100 pods, a few of them being parasitized by He tero spilus 
etiellae Rohwer. 
A" heavy infestation of the "pulga Americana" (Systena basalis J. Duv.), 
normally a flea-beetle pest of tobacco, has\been noted on sweotpotato at Rio 
Piedras, at least half the superficial leaf area of vines at one end of a field 
being eaten by these beetles. 
The sweotpotatoes were also heavily infested with Cylcif? foimicarius Fab., 
the adults of which feed from the under side of the leaves en petioles, midribs, 
and the larger veins. This insect has also been reported as attacking cotton 
seedlings in a field possibly half a mile away from the sweetpotato field. 
Despite the very imperfect clean-up of cotton fields last year and the 
small area planted to cotton this year on the north coast, infestation by the 
pink boll worm ( Pectinophora gossypiella Saund.)is very low by the middle of 
the picking season, no infestation of more than 10 per cent being noted in numer- 
ous fields examined between Isabela and Arecibo on August 4, and in two fields 
no infested bolls were found. 
INSECT CONDITIONS IN HAITI FOR KAY, 1932 
By Andre Audant. 
Service National de la Production Agricole 
Port-au-Prince, Haiti 
Young shoots of sugarcane are infested with the sugarcane mealybug ( Pseudo - 
coccus boninsis Kuwana) . 
The cotton leaf worm ( Alabama argil lace a Hbn.) has appeared at Hatte-Lathan, 
the cotton experiment farm near Port-au-Prince . This year the outbreak was most 
severe and the damage done in some places ran as high as 80 per cent. 
Corn in the southern and central parts of Haiti is attacked by the corn ear 
worm ( Heliothis obsoleta Fab . ) 
An outbreak of the fall armyworm ( Laphygr.a frugipcrda S. & A.) appeared at 
Hatte-Lathan, the worms destroying the grass, P^iiicum op., very rapidly. 
The sphinx worm P rotoparce sexta Johan. occurred on tobacco lerves of the 
southern plantations, causing little damage. 
The melon aphid ( Aphis gossypii Glov.) is very abundant on cucumbers and 
melons in the central plains.
