NOTES FROM ANNUAL REPORT ON INSECT CONDITIONS IN PORTO RICO 
July 1, 1930, to June 30, 1931 
M. D. Leonard 
Insular Experiment Station, Rio Fiedras, Porto Rico 
A leafhopper, Agallia albidula. Uhler, was common on watermelon vines 
at Arecibo on November 4, 1931 (Mills and Anderson; P. "7. Oman det.). 
This species has apparently not been definitely recorded before from 
Porto Rico. 
The woolly white fly ( Aleuro thrixus floccosus Mask. ) moderately in- 
fested about 20 young Meyer lemon trees on the Station grounds in April at 
Rio Piedras. 
The bamboo scale ( Asterolecanium bambusae Bdv. ) (H. Morrison det.), 
was reported as heavily infesting bamboo at Cidra and at Mayaguez in August 
and September (A. S. Mills) and as infesting bamboo at Maricao in January 
(A. G. Karley). It was, however, undoubtedly generally distributed and 
common throughout the Island. 
The eggplant stem-borer ( Bar! s tor qua ta ■ Oliv.) found on beans. 
An adult of the eggplant borer Baris torquata Oliv. was found on a 
bean leaf at Rio Piedras on Feb. 14, 1931. (A. S. Mills; L. L. Buchanan 
det.). 
Specimens of Blissus leuco-pterus var. insularis Barber, were found on 
a garden pea plant from Vieques Island, September 10, 1930 (A. S. Mills; 
H. G. Barker det.). 
Larvae of a moth, Brachyacma palpigera Wlsm., were common during the 
summer and fall in dry r>ods, and moths were reared from material from sev- 
eral localities. A prototrypid parasite of the larvae, Paralitomastix n. 
sp. (A. 3. Gahan det.), was found in as high as 50 Der cent of the larvae 
in some collections made. 
The weevil Callosobruchus chinensis L. was found working in dry pigeon 
pea pods at Rio Fiedras, August 8, 1930 (A. S. M. ; H. S. Barber det.). 
The palm aphid ( Cerataohia lataniae Bdv.) was found badly infesting a 
plant of C yrtoxiodium wpodfordia in Santurce on March 4, 1931 (Faxon and 
Mills; H. Morrison det.). 
A leaf beetle, Cerotoma denticornis Fab., was fairly common on string 
beans at the Station during March and April but apparently not doing much 
damage. No other definite observations were made during the year, but the 
insect was probably fairly common and general, as is usual wherever string 
beans were grown.
