On forage crops, apply carbaryl (Sevin), diazinon, malathion, or naled (Dibrom) . 

 No interval is required between the application of malathion or carbaryl and har- 

 vest. However, allow 4 days between application and harvest when using naled, 

 and 7 days for diazinon. 



Blister beetles . These long, narrow, soft -bodied beetles are the ones that cause 

 a blister to form, when smashed on tender skin. During the larval stage, they 

 live in grasshopper egg pods. For this reason, we expect to have more blister 

 beetles this summer than in past years. Control measures are not usually needed. 



HOMEOWNER INSECTS 



Picnic beetles . These tiny black beetles with the orange to yellow spots on their 

 backs are beginning to make their presence known, especially in raspberry patches 

 and in garden areas where vegetables are overripe or rotting. These beetles are 

 attracted to food odors, and are often uninvited guests at backyard cookouts or 

 picnics. 



For control around the home, harvest fruits and vegetables before they become 

 overripe. Dispose of spoiled produce. To kill the adult beetles, spray with 

 malathion, diazinon, or carbaryl (Sevin) in and around garbage cans. Spraying 

 shrubbery and tall grass with any of these insecticides before a cookout will 

 greatly reduce the number of picnic beetles. 



Follow the directions on the label. Check plants that may be injured if sprayed 

 with the insecticide you are using. Either 0.1-percent pyrethrin or 0.5-percent 

 dichlorvos (DDVP) spray in pressurized cans will give a quick knockdown of beetles 

 that suddenly move into an area. 



Elm leaf beetles . This pest has begun to hatch and feed, especially on the Chi- 

 nese species. These dirty-yellow and black larvae feed on the undersides of the 

 elm leaves, causing them to appear silvery at first then skeletonized with only 

 the leaf veins remaining. A spray now using 2 tablespoons of carbaryl (Sevin) 

 as a 50-percent wettable powder per gallon of water will control this insect. 



Drain flies . These small, hairy-winged , moth- like flies are appearing around 

 basement floor drains, sewer openings, and similar areas. Their eggs are laid 

 in decaying organic matter. The young maggots feed on the material in such damp 

 places, especially drain traps. Drain flies are harmless, but can easily be 

 controlled. 



Sanitation is the basic step. Clean-out overflow drains, drain traps, and cellar 

 drains with any commercial drain cleaner that will clean and disinfect the main 

 and the overflow drains. Pouring boiling water or rubbing alcohol into the over- 

 flow drain will also eliminate these maggots quickly. 



Grasshoppers . Home gardeners are now finding a large number of grasshoppers in 

 and around their gardens. Hard rains have killed many of them, but areas that 

 missed the rains could be heavily infested. 



The home gardener can use malathion or carbaryl (Sevin) to control this pest. 

 It will also pay to spray the borders around the garden as well as the vege- 

 tables being attacked. Allow three to five days to elapse between treatment 

 and harvest.
