VICKERY: STRIPED GRASS LOOPER 
405 
larvae attached to it, but we were not successful in rearing the adults. 
This was the only case of parasitism observed. 
The following natural enemies have been recorded in the literature: 
In Trinidad, Urich (5) mentions blackbirds ( Quiscalus crassirostris , 
Crotophaga ani) and parasitic flies. In British Guiana, Bodkin (9) 
records the Demerara robin (. Leistes guianensis ), the ladybird beetle 
(.Megilla maculata ), and a bacterial disease. In Porto Rico, Van Dine 
(7) records a carabid beetle ( Calosoma alternans Fabr.), blackbirds 
(<Crotophaga ani , Holoquiscalus brachipterus ) and a tachinid fly (Lin- 
naemya fulvicauda Walton). In Brazil, Hempel (4) records an unde¬ 
termined tachinid, and a hymenopterus parasite in small numbers, and 
several species of birds. 
Control Measures 
No experiments were tried with control measures at Brownsville, 
but measures similar to those used for army worms would probably be 
useful. 
In British Guiana, Bodkin (9) advises burning of badly infested 
fields of grass when the insect is in the pupa stage in order to prevent 
further infestations. For infested rice in the nursery beds he recommends 
flooding. For sugar-cane he recommends the use of arsenate of lead 
although the usual method employed is hand picking the larvae. In 
Brazil, Hempel (4) recommends the burning of infested grass and the 
use of furrows to confine the migrating larvae.
