Forage Insects 



Spittlebug adults are numerous in many clover and alfalfa fields in northern sec- 

 tions. Some froth masses are still present. But as the bugs mature, these masses 

 will disappear. The adults are tan, brown, black, or brown-and-white mottled, 

 wedged- shaped, jumping insects (1/4-inch). They will spread out now and feed on 

 a variety of crops until late August. Then they will return to the clover fields 

 to lay their eggs. 



Homeowner Insect Problems 



Plan your home fly control program now before flies become too numerous. Follow 

 these steps: 



1. Be sure garbage and refuse containers have a solid bottom and a tight lid. 

 They should be emptied at least once (preferably twice) each week. 



2. Scatter boron (Borax) powder on the soil beneath garbage or refuse containers 

 to kill any maggots that may pupate on the soil. 



3. Keep window and door screens in good repair to prevent flies from entering. 



4. In attached garages, under breezeways, or on porches, hang one dimetilan fly 

 band (Snip fly band) per 75 square feet. Wipe the bands about once each month 

 with a damp rag to remove dust deposits. Flies landing on the bands will be 

 killed before they can enter the house. The bands will kill flies for a full 

 season. 



5. Hang one 20-percent dichlorvos (DDVP Vapona) plastic resin strip for every 

 1,000 cubic feet of space (about one per room) in the kitchen and in other 

 rooms where flies congregate. The dichlorvos vaporizes slowly, killing flies 

 and mosquitoes without harming people or pets . These strips are effective 

 for about 4 to 6 weeks. As an added precaution, hang the strips out of the 

 reach of children and away from fish bowls or food counters . 



In place of the dichlorvos resin strips, you can use a 0.1 -percent pyrethrum 

 space spray, applied from a pressurized can for quick knockdown of flies and 

 mosquitoes. Repeat treatments will be needed with the space spray. 



First-generation elm leaf beetles are skeletonizing the leaves of Chinese elms 

 in the central sections. The small dirty yellow- to-black worms feed on the under- 

 sides of the leaves. Commonly, they congregate in large numbers next to the trunk 

 at ground level when ready to pupate. A spray of carbaryl (Sevin) --using 2 pounds 

 of 50-percent wettable powder per 100 gallons of water- -or lead arsenate- -using 

 4 pounds of wettable powder per 100 gallons of water- -is effective. An additional 

 treatment may be needed in late July in southern sections, in August in the central 

 sections, for second-generation worms. 



Cottony maple scales are present in some areas on soft maples and other trees and 

 shrubs . The appearance of white waxy masses (contain hundreds of eggs) on twigs 

 and branches is the identifying characteristic. (Heavily infested branches may 

 look somewhat like they are decorated with popcorn.) These eggs laid by the
