in Texas the infestation remains almost as widespread as before, but 

 much less in amount. Claims arising in Texas for cotton condemned 

 and destroyed as being within five miles of infestation amount to> 

 something like £8,000, which, under the terms of the Pink Bollworm 

 Act, will probably be paid by the State. It is pointed out that 

 eradication of the pest is impossible in one year and that a longer 

 non-cotton period is required. The larvae of P. gossypiella have been 

 found to be very resistent to water and it is thought that probably 

 in a district like that of the Great Bend of the E,io Grande they may 

 be largely spread by water carriage in bolls or parts of the cotton plant 

 caught up by flood waters. While in Texas the insect has confined 

 itself strictly to cotton, it can, in the absence of its natural host, subsist 

 on many related plants. 



The quarantine action taken by various States and Canada with 

 regard to the European corn borer [Pyransta nuhilalis] is quoted in a 

 statement giving the effective date of the quarantines, the plants 

 covered and the States or areas concerned. 



A hst of current quarantine and other restrictive orders relating to 

 various plants and insects is given.
