Bee Poisoning (taken from the Cornell University Chemicals Pesticides Newsletter) 



Bees are an essential part of our agriculture. Most bee poisoning occurs when 

 pesticides are applied to crops while in bloom. However, some fields, though not 

 in bloom, will have weeds in bloom and selection of the safest materials available 

 should be made to keep poisoning to a minimum. Spraying in the evening or early 

 morning will help. 



Other hazards are: 



1. Drift of toxic sprays or dusts on to adjoining crops which are in bloom 



2. Contamination of flowering cover crops when orchards are sprayed 



3. Bees coming into contact with insecticide residues on plants 



4. Bees drinking or touching contaminated water on foliage or flowers 



5. Bees collecting contaminated pollen or nectar 



6. Bees collecting insecticidal dusts with pollen (arsenical materials and Sevin 

 are especially dangerous because they may be stored with pollen in the hive 

 and later fed to brood; hazardous amounts of insecticides have not been found 

 in honey) 



Cooperation between the beekeeper and the grower should be a major consideration 

 in reducing bee poisoning. Try to work together to reduce the chances of poison- 

 ing. Remember that foraging bees may travel 1 or 1-1/2 miles. Do your part to 

 reduce bee poisoning.

HOMEOWNER INSECTS 



Fall webworms are defoliating certain trees- -especially birch, ash, and elm. 

 These pale-green or yellow worms (with a dark stripe down the back and a yellow 

 stripe along each side) spin a web over the ends of the branches and skeletonize 

 the leaves inside. They continue to extend the web to take in fresh foliage. 

 The damaged leaves curl, turn brown, and dry up. 



A spray of carbaryl (Sevin) , using 2 tablespoons of the 50-percent wettable 

 powder per gallon of water, is effective. 



Aphids are heavy on many kinds of trees, shrubs, and flowers. These small, soft- 

 bodied, sucking insects (green, yellow, black, or red) secrete a sticky material 

 called "honeydew." This sugary secretion coats leaves, making them glisten. 

 Cars parked beneath infested trees become covered with sticky spots. Ants are 

 often numerous on aphid- infested plants, where they feed on the aphid secretions. 

 White specks are usually visible on the leaves; these are the cast-off skins of 

 the aphids--not eggs. Leaves of heavily infested plants will curl, yellow, and 

 eventually brown.
