those emerging from the middle to the end of June do not stop feeding 

 until early in July. During the post-dormant stage the food 

 consumed daily is not one-tenth as much as is eaten during the 

 pre-dormant stage. 



//. punctata is an important pest of clover, though its annual toll 

 usualh^ passes unnoticed. It seldom devastates entire fields, however, 

 because the larvae are checked by a fungus, Empusa sphaerospernia, 

 which kills them in April and May and again in October and November. 

 A small beetle, Collops qitadrimaadatus, F., feeds on the eggs, and 

 one of the tiger beetles, Cicindela repanda, Dej., probably preys on 

 the larvae. Poultry and birds, of which a list is given, feed on H. 

 punctata, which also forms the food of toads and frogs. 



Usually the need for remedial measures becomes apparent too late. 

 It is a good practice to pasture lightly all first-year clover in the 

 autumn or to clip it back in spring, and further to hinder the increase 

 of this insect in the locality by thoroughly ploughing under the second- 

 year crop in the autumn. These measures seem all that is ordinarily 

 necessary to prevent injur}^

The work of the insecticide and fungicide board for the year ended

 for the protection of insecticides and fungicides from adulteration 

 are described.

The work for the year ended 30th June 1920 is reviewed, and a list 

 of current quarantine and other restrictive orders is appended. 

 Numerous reinfestations by the pink bollworm {Platyedra gossypiella) 

 have been found in Texas. The entire areas involved were immedi- 

 ately subjected to intensive cleaning operations. The Pink Bollworm 

 Act of 1920 provides for the prompt destruction of the cotton in infested 

 fields. In spite of the compensation to planters for crops destroyed, 

 their opposition put a serious check on the State and Federal control 

 work. It may become necessary to consider the extension of the 

 existing Federal quarantine to cover the entire State as the only 

 means of protecting surrounding States from the movement of materials 

 from Texas capable of carrying the pest. Under existing conditions 

 in Texas there seems little likelihood that non-cotton zones can be 

 adequately enforced in the future, but eradication may still be possible 

 with adequate State legislation and thorough work in connection with 

 still existing non-cotton zones. The bulk of the information given 

 with reference to the existing conditions in Louisiana and quarantine 

 regulations have been noticed elsewhere {R.A.E., A, viii, 511], as 

 has also the information concerning the Furopean corn borer {Pyrausta 

 nubilalis, Hb.) [loc. cit. and ix, 14, 159]. 



In view of the existence of Eriophyes gos.sypii. Hanks (cotton blister 

 mite) and a cotton boll disease in Porto Rico, a quarantine has been 

 issued against Porto Rican cotton, cotton seed and cotton seed 

 products.
