WEISS: RECENT IMPORTED PESTS

that in many cases, inspection work is entrusted to students and to 
inspectors whose usefulness does not extend further than an ability 
to recognize San Jose scale, crown gall, gipsy moth egg masses and 
brown tail nests. We have tried all kinds of inspectors and have 
come to the conclusion that considering the importance of inspection 
it pays to employ competent men. It is true that during the rush 
seasons we are forced to employ men whose training leaves much to 
be desired but these men are certainly not placed at danger points. 
The finding of various foreign insects in New Jersey during recent 
years has been due entirely to the activities of competent inspectors. 
In order to prevent these pests from spreading within the state and to 
prevent them from being carried outside of the state, various methods 
of control have been pursued. The following is a list of the more 
important insects together with the treatment which has been fol¬ 
lowed in New Jersey. 
Gryllotalpa gryllotalpa L. (Orthop.). The European mole cricket has 
been present for several years in a small nursery area planted to a 
rose garden and exhibition stock. There is very little danger of this 
insect being carried out of the nursery in soil around the roots of plants 
as long as it is not allowed to spread. For the past two years, the 
entire infested area has been gone over and the egg nests destroyed 
during June and July. Special men, expert in detecting the nests, do 
this work and up to the present they have been successful in keeping 
this European pest down to comparatively harmless numbers. 
Monarthro palpus buxi Lab. (Dip.). The boxwood leaf miner has 
been found in several nurseries and on one estate in New Jersey. On 
account of unsatisfactory methods of control for this species, infested 
plants in nurseries are ordered destroyed and certificates are withheld 
until this has been accomplished. 
Evetria buoliana Schiff. (Lep.). This species, known as the European 
Pine-Shoot Moth, was found several years ago in two nurseries. Cer¬ 
tificates were withheld at that time until every infested shoot had 
been cut off and destroyed. At the present time no infestations are 
known to exist in nurseries. 
Gracilaria zachrysa Mey. (Lep.). This moth, known as the azalea 
leaf miner, has for the most part confined its attention to azaleas in 
greenhouses and is not likely to be shipped outside of the state. Spray¬ 
ing with arsenate of lead and fumigation with tobacco extracts have 
been fairly successful in controlling it. 
Plagiodera versicolor Laich (Col.). This Chrysomelid exists in sev¬ 
eral nurseries and other localities, but feeding as it does in both larval 
and adult stages on the foliage of poplar and willow, it is readily 
controlled by arsenicals and is in no danger of being transported on 
nursery trees.
