can. Ent. 124: 577-585 (1992) Acephate implanted in trunks of black spruce, Picea mariana (Mill.) B.S.P., trees in the fall, 3 weeks before female bud flush, and at female bud flush reduced insect damage to cones and increased seed yields for 1 year. Second-year effects of the implants reduced insect damage to cones, but without increased seed yields. In the 2nd year, cones from trees treated at bud flush had the least insect damage and the highest residues of acephate and its toxic metabolite, methamidophos. Damage to treated cones by the spruce cone maggot, Strobilomyia neanthracina Michelson, the dominant insect in untreated cones, was insignificant in the 1st year and was reduced in the 2nd year.

Stem implants are also portable and practical to use in remote areas (Reardon et al 1985) and could protect trees of high value. (Stevens and Leatherman 1982).…”

“…Protection is possible by spraying such trees from a helicopter (Miller and Hutcheson 1981). Another possibility for individual orchard trees and plus trees is stem implanting or injection of insecticides (Koerber 1979, Merkel and DeBarr 1971, Reardon et al, 1985. In this report we present results of field trials to test the efficacy of stem injections of liquid dicrotophos (BidrinB) and oxydemetonmethyl (Metasystox R@) by means of Mauget@ injectors, and implants of a soluble powder formulation of acephate (OrtheneB) by means of AceCap@ capsules for control of defoliating and cone-damaging insects on white spruce.…”

White spruce trees were injected with a liquid formulation of dicrotophos (0.6 g Al/cm DBH) to evaluate the effect of injection times on cone and seed damage by insects. Injections of liquid formulations of dicrotophos (1.1 g Al/cm DBH) and oxydemetonmethyl (0.7 g Al/cm DBH) (approximately four days after the peak of flowering) were evaluated for control of defoliation and cone and seed damage by insects. Implants of a soluble powder formulation of acephate (0.5 and 1.0 g Al/cm DBH) (approximately two weeks after the peak of flowering) were evaluated for control of cone and seed damage. A single injection of dicrotophos reduced cone damage for up to four weeks after the peak of flowering by insects that oviposit and feed after pollination (seed moth, cone maggot, cone-axis midge, and seed inhabitants) whereas damage by insects that begin feeding before pollination was not reduced by single injections after pollination. Dicrotophos and oxydemetonmethyl reduced defoliation by spruce budworm at upper, middle, and lower crown levels for two seasons following injection. In the treatment year, these injections reduced the proportions of cones damaged by insects that feed after pollination whereas damage by insects that feed before pollination was not reduced; cone seed counts were increased 558% by dicrotophos and 267% by oxydemetonmethyl. In the season after injection the proportion of cones damaged by budworm was reduced by both insecticides while seed inhabitant damage was reduced by dicrotophos. Neither insecticide reduced damage by other insects; nonetheless, cone seed counts were increased 90% by dicrotophos and 115% by oxydemetonmethyl. In the year of treatment, implants of acephate reduced the proportions of cones damaged by seedmoth but not other insects whereas, in the season after implanting, they were effective against coneworm, seed moth, cone maggot, and seed inhabitants.

“…Metasystox-R, applied in the Mauget injectors (INJECT-A-CIDE), is effective for protection of cone crops in coniferous species 9,10,11 and for reducing damage by foliage-feeding insects. 12 This treatment is also registered for protection of western conifers from numerous bark beetle species 13 and is currently marketed for preventive and remedial control The effectiveness of registered application rates of the insecticide metasystox-R applied with Mauget tree injectors (INJECT-A-CIDE) was assessed in two strategies: (1) treatment of trees before western pine beetle attack (preventive treatment), and (2) treatment of trees after attack by western p i n e b e e t l e ( r e m e d i a l treatment) for protection of individual, high-value ponderosa pine.…”
