Gallery injections with six insecticides and three fumigants were tested for comparative effectiveness in controlling two hardwood borers, the carpenterworm, Prionoxystus robiniae (Peck), and an oak clearwing borer, Paranthrene simulans (Grote). The insecticides were injected to treat both the phloem-cambium mine and gallery entrance; the fumigants were injected only into the gallery entrance, which was then plugged. Diazinon, chlorpyrifos, and carbaryl gave good to excellent control of both borers. Lindane and endosulfan were effective only at comparatively high rates. Bacillus thuringiensis was ineffective even at very high rates. The three fumigants (carbon disulfide, Serafume, and paradichlorobenzene) provided complete control. The gallery injection technique was deemed feasible for use against borers in high-value trees. Gallery injection has advantages over bark sprays because it can give satisfactory control of borers already established in galleries and limits chemical application to a few galleries instead of entire trees or stands of trees.
