Cucumber Beetle. — Wkly. Press Bull, Pennsylvania Dept. Agric, 

 Harrisburg, iv, no. 25, 26th June 1919, 1 p. 



The striped cucumber beetle [Diabrotica vittatu] has been causing 

 great damage to young cucumber and melon plants in Pennsylvania. 

 Covering the small vines with 2 teaspoonfuls of lead arsenate to 

 1 U.S. gal. of Bordeaux mixture is suggested as a possible remedial 

 niBasure. Young plants should be covered with cheese cloth.

This paper, which is written from the point of view of the lac 

 cultivator, describes the best methods of pollarding Butea frondosa, 

 in order to obtain good broods of this scale-insect [Tachardia lacca].

The pests reported on tea during 1918 included Lachnosferna 

 imryressa (white grub), which attacks the plants in nurseries and to 

 a less degree in the field by cutting the roots. The adults emerge 

 in April and may attack the leaves. As they are attracted by Hght 

 they may be collected by means of lamps suspended over trays of 

 water or some sticky solution. A smaller cockchafer, Serica assa- 

 mensis, appears about the same time, but the damage it does is 

 confined to a few bushes. Another beetle appearing in April is the 

 orange beetle, Diapromorpha melanopus. 



Lepidopterous pests include Andraca bipunctata (bunch caterpillar) 

 occurring from April to July. Heterusia magnifica (red slug) is 

 present in February, March and April, and the female moths can 

 be collected at light in May, June and July. Clania spp., Psyche spp. 

 and AcanthojysycJie spp. (bagworms) are active from January to May ; 

 the cases should be collected during the cold weather before the 

 contained eggs have hatched. Sprays are of most value from March 

 to April. Zeuzera cojfeae (red borer) makes its appearance as an 

 adult in May ; affected shoots should be cut out in April and imme- 

 diately burnt. Thosea cervina (nettle grub) appears in the adult 

 stage in March and April and the caterpillars in June, and those of 

 the Lymantriids, Orgyia, Olene and Etiproctis from March to May 

 and the moths from May to June. Arbela spp. (bark-eating borers) 

 are most easily destroyed during March and April, when they remain 

 3 or 4 weeks in the pupal stage in the larval boring. Comocritis pieria 

 is best dealt with by the destruction of the larval webbing in April. 

 Gracilaria theivora (tea leaf -roller) and Homona menciana (tea tortrix) 

 are found in the curled tips of the leaves in March, and Agriophora 

 rhombota (sandwich caterpillar) occurs from March to May. 



Other pests include a cricket {Brachytrypes portentosus), against 

 which poisoned bait is the most useful remedy. For Helopeltis 

 theivora (tea mosquito) the drenching of tea bushes with lime-sulphur or 

 liver of sulphur solution is suggested. Empoasca flavescens is present 

 in all stages by April. Toxopt^ra Coffeae [Ceylonia theaenola)- (tea a{)his)
