Infestations and damage in NEVADA were at about the same levels as in 1961, with the heaviest infestations occurring during August. Bollworm is becoming an increasing problem in cotton-growing areas of Nevada. Infestations were generally higher than in 1961 in ARIZONA. Damaging populations were present during August in some areas of that State. In NEW MEXICO, the heaviest bollworm infestations in cotton, since the insect survey program started in 1957, existed in 1962. Beginning about the middle of June and continuing until the middle of October, it was necessary to follow a strict control schedule to prevent severe damage in Dona Ana and Eddy Counties. Bollworm was the most damaging insect of cotton during 1962 in TEXAS. Heavy infestations occurred in all areas of the State, with serious damage usually occurring before the populations were brought under control. TOBACCO BUDWORM (H. virescens) was locally heavy during the late season in central, west central, south central and southern areas of Texas. This insect was not a serious problem generally. In OKLAHOMA, damaging populations of bollworm existed throughout the State from late July through late September. The high- est populations existed from the latter part of July through August. Damage from this species showed considerable increase over 1961. Bollworm and tobacco budworm have become of greater importance in ARK
