HOMOPTERA 



This group contains eight species, four of which were found estab- 

 lished on outside stock and four on greenhouse plants. The four on 

 outside stock came originally from Japan and are Antonina crawi 

 CklL, the cottony bamboo scale on bamboo, Leucaspis hambusoe 

 Kuwana, another scale insect on bamboo, Aspidiotus tsugce Marlatt 

 on Japanese hemlock and Pseudococcus kraunhice Kuwana, a mealy 

 bug on Taxus cuspidata brevifolia. Three of the greenhouse species 

 are coccids which were found infesting orchids. These are Targionia 

 biformis CklL, from Brazil and Venezuela, Chrysomphalus persece 

 Comst., from Guatemala, and Chrysomphalus rossi Mask., from the 

 Philippine Islands. The other is a species of white fly (Aleyrodes 

 sp.) which is continually being introduced into New Jersey green- 

 houses on azaleas from Belgium. 



It must be understood, of course, that we are not idle after an infes- 

 tation is found and steps are always taken if possible to exterminate 

 it or to prevent its spread. Unfortunately, however, this is not 

 always practical, due to the favorable surroundings of the infestation 

 or ignorance of its existence until considerable damage has been done. 

 Thus the burden of the entomologist is increased by additional 

 correspondence, additional insect pests to combat and the necessity 

 of obtaining additional funds for that purpose or stretching an already 

 meager appropriation to cover it, to say nothing of the damage which 

 many foreign insects are capable of doing. 



What is occurring in New Jersey must to a certain extent be hap- 

 pening in other states, dependent, of course, on the amount of imported 

 stock received. During the year 1914, 11,742 cases of nursery stock 

 came into New Jersey from Europe and South America and during 

 the spring of 1915, 5,405 cases were received. New Jersey, therefore, 

 is in greater danger from foreign pests than most other states, but 

 once established there, a natural spread to other states would finally 

 take place. These recently found foreign pests established in New 

 Jersey are not by any means the result of a laxitj^ in the inspection 

 service, as every precaution is taken that our funds will permit. 

 In most cases they are insects which have entered undetected by the 

 inspector, sometimes through his ignorance of foreign pests, sometimes 

 on account of individual carelessness, but mostly on account of the 

 impossibility of examining every leaf, twig, root and particle of soil 

 around the roots of a plant and having anything left that will grow, 

 especially when one is called upon to inspect hundreds of plants every
