time. Lady beetles that migrate long distances between habitats 

 are very difficult to establish locally by man in his efforts to 

 promote the control of pest aphids by this means. On the other 

 hand, many lady beetles that prey on more stationary host pests 

 (such as scale insects) have been introduced into new environments 

 quite successfully. A small black lady beetle (Stethorus) has 

 been encouraged via pest management techniques in Pennsylvania and 

 is apparently doing a good job of controlling orchard mite popula- 

 tions in that area. Ladybeetles are predators in both the adult 

 and larval stages. Adults most often observed are the reddish- 

 orange beetles generally with black spots (Fig 7); however, there 

 are many darker, smaller species which feed on scale insects, mites 

 and mealybugs. The reddish-orange species generally feed on aphids 

 of almost any species, and occasionally on the eggs of moths. 



Predacious stinkbugs (Fig 8) are not numerous in most orchard situ- 

 ations and additionally they often prey on beneficial species such 

 as lacewings and lady beetles. For these reasons, their usefulness 

 to orchardists is probably minimal. 



Praying Mantids (Fig 9) have received much attention as predators 

 during the past decade, and mantid egg cases may be purchased and 

 attached to trees and shrubs in gardens. Their fame is probably 

 not entirely justifiable because of the thousands of young mantids 

 which come out of the egg cases, only a few will survive. They 

 do have avid appetites and eat many insects; however, many of those 

 consumed are either beneficial or are of little or no consequence 

 to the orchardist. They commonly eat their own kind as well. Many 

 of the advertisements about these insects are grossly false in 

 their claims concerning the numbers and types of prey consumed.
