ABSTRACT Insects feeding in conifer cones are difficult to control with nonsystemic insecticides. Newly developed systemic insecticides that can be injected into tree trunks may be a possible way of reducing both insect damage and negative side-effects to the surrounding environment, compared with conventional spraying. Several insecticides that could be injected into tree stems were tested on Picea abies (L.) Karst. In one experiment, insecticides (bifenthrin, deltamethrin, abamectin, and… 
Insect pests of Norway spruce cones: incidences and altitude preferences with emphasis on Cydia strobilella (L.)
TLDR
Cone damage resulting from C. strobilella infestation was greater in those forest vegetation zones located in lowlands and uplands rather than in highlands and at lower mountain elevations, and infestation by D. abietella was unrelated to elevation.
Isolation and expression profiles of gibberellin metabolism genes in developing male and female cones of Pinus tabuliformis
TLDR
The expression pattern of GA metabolism genes indicated that GAs play different roles at the early and late stages of cone development, and the active sites of all GA metabolism enzymes were conserved during the evolution of land plants.
Pollen dispersal and genetic structure in a cajuput (Melaleuca cajuputi subsp. cajuputi) seed orchard in Yogyakarta, Indonesia
ABSTRACT Cajuput (Melaleuca cajuputi subsp. cajuputi) is cultivated widely in Indonesia for its medicinal foliar essential oil. Breeding programs of cajuput have established seed orchards for the
Intracone variation explains most of the variance in Picea abies seed weight: implications for seed sorting
TLDR
Variance component analysis showed that the intracone variation explained a larger proportion of the total variation in seed weight than did the intercone/intertree or interclone variation.
Molecular characterization and its binding properties of general odorant binding protein 2 in Dioryctria abietella
TLDR
Exploring the functions of DabiGOBP2 can help in better understanding the mechanism of the olfactory system of D. abietella and developing novel strategies to control this pest.
Seed quality attributes in seedling production of Norway spruce (Picea abies (L.) Karst.)
TLDR
Investigation of the effect of seed quality attributes on seedling production and whether it is possible to enhance germinability and seedling health through seed soaking treatments indicates that weight-based seed sorting may have a smaller impact on the genetic diversity of seed lots than previously thought.

Systemic Insecticide Injections for Control of Cone and Seed Insects in Loblolly Pine Seed Orchards—2 Year Results
TLDR
Three systemic insecticide treatments were injected one or two times into loblolly pine, Pinus taeda L., during a 2 yr period in a seed orchard in east Texas, reducing cone and seed losses from insects by 86% and reducing coneworm damage by 94–97% during the study period.
Evaluation of Systemic Insecticides as a Treatment Option in Integrated Pest Management of the Elm Leaf Beetle, Xanthogaleruca luteola (Müller) (Coleoptera: Chrysomelidae)
This study evaluates the efÞcacy of two systemic insecticides (imidacloprid and abamectin) in an operational setting and their suitability to be incorporated into an integrated pest management
Evaluation of systemic insecticides as a treatment option in integrated pest management of the elm leaf beetle, Xanthogaleruca luteola (Müller) (Coleoptera: Chrysomelidae).
TLDR
Treatment in the first generation appeared to provide protection against damage in that generation as well as the second and third beetle generations and both materials become active within the tree canopy very quickly and are compatible with a management program that determines the need for treatment based on monitoring for egg clusters at peak density.
Effects of root pruning and stem injections with Gibberellin a 4/7 on flowering and cone harvest in three Picea abies seed orchards
TLDR
In two trials, an approximately three‐fold increase in number of cones per tree was obtained after root pruning and GA injections, which is a commercially acceptable increase.
Use of Soil and Trunk Injection of Systemic Insecticides to Control Lace Bug on Hawthorn
TLDR
This study indicates that systemic insecticides applied through soil injection and trunk injection have potential for controlling sucking insects that feed on ornamental trees.
Effects of gibberellin A4/7 stem injection on seed cone production in mature black spruce
TLDR
It is shown that GA4/7 was able to induce additional cone buds during a very heavy cone crop and potential effects of gibberellin treatments on phytophagous insects are discussed.
Bacillus thuringiensis Variety kurstaki × aizawai Applied to Spruce Flowers Reduced Dioryctria abietella (Lepidoptera: Pyralidae) Infestation without Affecting Seed Quality
TLDR
The Bt variety kurstaki × aizawai treatment caused no reduction in seed quality as measured by seed weight or percentage of nonfilled seeds, and there was no difference in number of seeds per cone between the Bt-treated and untreated control cones.
Assessment of cone-damaging insects in a Swedish spruce seed orchard and the efficacy of large-scale application of Bacillus thuringiensis variety aizawai x kurstaki against lepidopterans.
TLDR
Investigation of the efficacy of large-scale application of the biological insecticide Bacillus thuringiensis variety aizawai x kurstaki in a Swedish spruce seed orchard for controlling damage caused by four lepidopteran species revealed that E. abietaria occurred in similar numbers to D. abetella and has probably been overlooked as a potentially serious pest in spruce Seed orchards in Sweden.
SPRUCE CONE INSECTS IN BRITISH COLUMBIA AND THEIR CONTROL

TLDR
The systemic insecticides dimethoate and formothion proved to be effective against these insects when applied as sprays following pollination in mid-June.
Oviposition strategies of conifer seed chalcids in relation to host phenology
TLDR
It is predicted that the presence of a larva in unfertilized ovules of all Pinaceae will influence the development of the female gametophyte by preventing its abortion and represents a much more efficient oviposition strategy than searching and locating only fertilized seeds.
