of weeds. Hand picking: must be rolieil upon by tlie fjardener as the 

 main remedy. The bu^s may be collected from the vines, from (he 

 ground l)eneath (hem, from boards used as (raps, or from scjuashes 

 |)lanted between the rows of the regular hills as tra])s for the scpiasli 

 bugs. The nymphs which ap})ear on innnature s(|uashes in the fall 

 may be drenched with an insecticide spray and thus the spring brood 

 will be considerably reduced in lunnbers. 



THE PICKLE WORM. 



The i)ickle worm has given considerable trouble to growers of 

 muskmelons, cucumbers, sfjuashes, and other related plants, especially 

 in the Southern States. In Georgia " careful experiments were made 

 to determine a simple and effective remedy for this pest. It was 

 found that the pickle worm shows a decided preference for the blos- 

 soms of the squash. This observation led to the use of the squash as 

 traj) ])lants. In these experiments it a])peared that muskmelons could 

 be etl'ectively protected against i)ickle worms b}' planting squashes 

 between the rows. The squash blossoms must be collected at fre(pient 

 intervals and destroyed. 



THE COTTONWOOD LEAF-BEETLE. 



The Cottonwood leaf-beetle, in addition to destroying the foliage of 

 cottonwoods used for shade trees, causes serious depredations on wil- 

 lows. This attack acquires considerable- importance in case of wil- 

 lows grown for the manufacture of baskets. In New York ^ it was 

 found that the infestation of basket willows with the cottonwood 

 leaf-beetle caused the willow Avhips to branch and thus rendered them 

 useless for basket-making purposes. It was found possible to protect 

 willows against the cottonwood leaf-beetle by three applications of 

 green arsenite, at the rate of 1 pound to 100 gallons of Avater. This 

 should preferably be used Avith lime as ordinarily recommended for 

 ]*aris green. The spraying should begin early in the season, the first 

 applicati(m being made before the beetles become numerous, and fol- 

 lowed by two other applications a Aveek or ten days apart. NeAvly 

 planted fields should be sprayed by ordinary apparatus until the 

 Avillows are large enough for machine sprays, after Avhich these may 

 be used. 



THE MEDITERRANEAN FLOUR MOTH. 



Mills and elevators frequently become infested Avith the Mediter- 

 ranean flour moth, and in several vStates the stations haA^e been called 

 upon to dcA^elop satisfactory remedies for the control of this pest.
