Practically 100 per cent infestation occurred in the College plots this oast 
year. Growers have been considerably alarmed over the appearance of this -nite 
but are now beginning to believe that it is of little importance. 
A mite that has attracted more attention is one of the leaf mites, letrar.y - 
chus sp., observed for the first time in the following varieties: P.O.J. 3725,272 
and 2878. One field of 2725 was found with about one-half of the cane leaves 
moderately to heavily infested during February. 
COFFZF 
The coffee "broca," Stephanoderes hamoei Ferr., was observed for the first 
time in the State of Minas Geraes on February 8, 1932. Undoubtedly the insect 
has become slowly established in most of the counties bordering the State of 
Sao Paulo during the past few years. However, not until the above date had 
there been any suspicion that the insect was present; it had disseminated over 
quite a large area. A survey was initiated in southern Minas Geraes during 
April and up to the present writing (January 31, 1933) 33 counties have been 
found to be infested through the more important coffee zones of the State. In- 
jury to the 1933 crop will undoubtedly be quite marked in the more heavily in- 
fested groves where means of control have not yet been undertaken. 
The green scale, Coccus viridis Green, has received more attention oy 
coffee growers this season. Many younger plantations were heavily infested 
toward the end of the year. The coccinelid Azya luteipes Muls. and the fungus 
Acrostala albus Pr. proved of great benefit in holding the scale in check dur- 
ing the wet season. 
COTTON 
The pink boll worm, Pectinonhora gossyoiella Saund. , continues to be the 
most important cotton pest in this part of Minas. In spite of the fact that 
all possible means of reducing the infestation from one year to the next are 
thoroughly practiced, severe losses occur annually in Vicosa. Counts made in 
July on the College grounds showed 50 to 80 per cent infestation of bolls. 
According to C. Moreira, this insect is common in the principal cotton-growing 
regions of Brazil but is not responsible for serious losses. 
The cotton leaf worn, Alabama argil lac ea Kbn. , appeared during January 
1932 in very small numbers. During the previous year parasites of th genera 
Spilochalcis and Microgaster (det. C.jP.W. Muaaebeck) reduced the infestation to 
a minimum. For this reason we are of the opinion that very few adults escaped 
to infest the plantings of 1932. The cotton worm may be found widely distributed 
throughout Brazil. 
The cotton aphid, Aphis gossyoii Giov., was present from March to harvest 
time but never increased to such an extent as to warrant control measures. 
The coccinellid Neda sangui nea L. was present in large numbers feeding on the 
aphids. 
Dysdercus fernaldi Ballou and Eur yo ph thalmus humilis Drury were both very 
common again this season in the cotton plots at the College. These "percevejos" 
undoubtedly are important agents in the transmission of anthracnose and other 
cotton diseases. Practically 100 per cent of the bolls were fed upon by these 
insects.
