January v'itnessed extreme frost damage in the South Atlantic States when a very severe cold wave spread over this region on the 5th and 6th of the r;onth. The Gulf region exper- ienced similar cold weatlier, and but for cloudy weather serious darrage would have oeen done in Floridc. On the 2d and 3d of January very severe cold weather was felt in California, and during the month the entire western region was dry and th East wet. The European corn borer made very slight increase in the infested terri-" tory in the western part cf its distribution.

Heretofore this region has been beyond the Kessian fly territory. A full account of the records since appears in the body of this bulletin. Apparently the numoer of larvae and adults in the field was considerably reduced.

The outbreak of the potato tuber moth on the Eastern shori of Virginia, which developed last fall, extends well up into Acccirac County.

This is the firs record of the occurrence of this insect as a potato pest in the Eastern United States. Up to that time this pest was known only from about I''esilla Park in Nev; Mexico and in southern Texas.

The discovery of the Oriental fruit moth in the vicinity of ValdAsta, Ga. The temperature, for the most part, has been well above normal with the exception of a cold snap in February throughout Eastern Canada. The snowfall in the VJestern Provinces was light, the open range being alro free from snow late in February so that no feeding of stock was necessary. Eight new tov.

Outoreaks of the cankerwom;S are expected to occur in several of the coun- ties around the western shores of Lake Ontario during the coming season. Several districts in Nova Scotia which in the past were important breeding centers of the brown-tail rroth nave oeen found to be rlear of infestation.

Illinois Elint: Abundant rains throughout the late sun-rrier and early fall of 19 23 caused a heavy growth of the volunteer wheat in stubblf fields throughout the State.

This wheat is roderaxely to heavily infested with the Hecsian fly and will provide sufficient spring adults for a moderately heavy infestation in the spring of 1? In the sovn fields there is very little infestation present except in the southwestern part of tne State, where a nucioer of fields were seeded early.

The infestations in these fields will run fron" 60 to 90 per cent. Nebraska M. On the basis of the field ODservation station conducted at Plattsrcuth, Cass County, in the fall of , da.

In most of these counties a high percentage of the - 11 - faiTiers awaited the announced date of safe seeding, and as a result these counties that contained so much heavy infestation by the fly in the spring showed comparatively little of it in the fall.

In other counties, unorganized, where the Hessian fly had not done J enough injury in the spring of to indicate that organized effort to secure a generaJ delay until the date of safe seeding, would be successful, the present infestation is more severe than it was a year ago-. This area of hea. In brief, the geography of the Hessian fly infestation at this time is different from that of a year ago chiefly in that the counties that were worst infested a year ago are now compara- tively lightly infested, while the present heavy infestation, ex- cept in Furnas County, is in counties that were not heavily enough infested a year ago to secure general interest in a program of late seeding.

Illinois Yif. Flint: No very extended examination of chinch bug hibernat- ing quarters has been mads up to this time. Those made thus far indicate about the average winter mortality in the central Illinois counties with a ratner high mortality, in some cases as high as 50 per cent, in the northern counties. These counties are just becom- ing irj'ested with the bugs. Missouri L. Haseman March 12 : In spite of severe winter on March 7 examination of clump and blue-grass harbors in sheltered places show live Dugs aoundant.

They were observed in short and scatter- ed grass shelters. Protection seemed poor, thougli, on south slope. This leads me to believe that we will have chinch bug trouble again this summ.

Massachusetts A. Naturally we would expect the first signs of returning to a minirnuja abundance to be from that section of the State.

Here in Anherst, early spring indications gathered from the egg masses are for a greater abundance of this species than last year. The same is reported by Mr. Calkins, another prominent grower of the sane general region. The egg masses are found in consider- aole numbers, even in well sprayed orchards, where of course they will not be allowed to increase to numbers enough to cause any serious injury once the season opens and the regular spray program is oegun to be put in practice, but this increased abundance over last year in these well- cared -for orchards is a very good indica- tion of the general upward trend of the pest.
