The cweetpotato weevil Buscepes "batatae Waterhouse caused as high as 14 
per cent losses in the more important varieties of sweetpotato in I College 
plots this season. 
IRISH POTATO 
The tobacco leaf -miner , S fegj. yxh^./rr- p-perc^lella Zell., absent firing t 
growing season, appeared after harvest, infesting the second growth of Irish 
potato or "suckers" in one planting at the College. This insect has not been 
observed in potatoes at Vicosa. 
In an Irish potato planting of approximately 5 acres, a species of Pseudo- 
coccus was found infesting the roots during November. 3y mid-December the e 
tire field was infested and serious loss resulted in the final yield. 
Tro species of Epicauta. are occp.sionally found feeding on Irish potatoes 
in Minas G-era.es. 
The potato flea beetle, ZPitrix cucumeris Harr., was present throughout 
the latter half of the growing season but was of very little importance in near- 
by potato fields. 
EGGPLANT 
In January, adults of Phyrdenus muricens Germ, were taken a number of times 
on eggplant. Larvae were not observed on the roots of the same plants despite 
the fact that ca.reful search was made for them. 
A dhrysomelid, Colas-pis sp. , is quite a. serious pest of eggplant. Larvae 
feed on the roots, and the adults consume quantities of the foliage, eating 
out large holes, thus weakening the plants to such an extent that they fail to 
produce. 
ONIONS 
The onion thrips, Thrifts t abaci Li .ad. , was very common in onion beds from 
August until October, 1932. 
CAB3AGE 
A dipterous leaf -miner, probably Agromyza sp. , was very numerous in cabbage 
and "couve" plantings throughout the season. The same species was reared many 
times from wild mustard. 
The cabbage aphid, Brevicoryne bra.ssicae L. , was occasionally observed V 
never in sufficient numbers to warrant control measures. 
The diamond back moth, Plutella maculi-.''ennis Curtis, was common all year 
attacking preferably "couve" rather than cabbie grown side by side. 
bea::s 
Larvnc of Lamprosema indicata Fab. (Det. "h I. ".Forbes) rppeared in March 
and until June caused slight losses in beans. The moths are very numerous .
