THE INSECTS OF NEW JERSEY. 



547 



RHOPOBOTA Led. 



R. vacciniana Pack. Throughout South 

 Jersey on cranberry bogs. The larva 

 is the "vine worm" or "black-head," 

 which is always injurious and often 

 ruinous; there are two broods, and the 

 winter is passed in the egg stage. Re- 

 flowing is the best method of control; 

 arsenites are useful if applied early; 

 late holding of water answers on a 

 level, shallow bog.

SPILONOTA Steph. (TMETOCERA Led.) 



S. ocellana Schiff. The "bud-moth"; occurs throughout the State. The 

 larva is known as the "bud worm" of apple and other fruit trees, 

 destroying fruit and buds in early spring. 



var. lariciana Hein. Occasional with the type; differs in having the 

 whitish median fascia almost obscured by the general brown color 

 (Kf). 



PHTHINOLOPHUS Dyar. 



P. indentanus Dyar. Essex Co. VII (Kf); Stone Harbor VIII (Dke); 5- 

 mile beach VI-VIII (div) ; larva webs leaves of huckleberry and bay- 

 berry (Kf). 



Sub- family TORTRICIN.E. 



PERONEA Curt. (TERAS Tr. ACLERIS Hb.) 



P. maculidorsana Clem, (hastiana Linn., part.) Throughout the State, 

 fall and spring. Moths hibernate and can be disturbed on mild days 

 of winter and early spring; larva on willow and apple (Kf). 



P. brewsteriana Rob. Essex Co. X, 10 to VI, 2 (Kf). 



P. pulverosana Rob. Essex Co. X, 1 (Kf). 



P. effractana Froel. (scabrana Curt.) Jersey City; Woodside VII 

 (Wdt). 



P. minuta Rob. Throughout the State and 

 throughout most of the year. Larva 

 on apple in general, and on huckleberry 

 and allied plants. In the cranberry 

 regions it attacks that plant by prefer- 

 ence, and is the "fire-worm" or "yellow- 

 head" of the cranberry grower. There 

 are three broods, that issuing in fall 

 being gray and forming the variety 

 "Cinderella" Riley. This hibernates 

 and in spring lays eggs for the summer broods, which are orange. 

 The remedial measures are renewing, when the larvae first appear, 

 late holding of water to compel the hibernating moths to oviposit 

 elsewhere, and the use of arsenites. 



P. oxycoccana Pack. Also a cranberry feeder and may be a large form 

 of the preceding.
