Hypericin content of Nova Scotia biotypes of Hypericum perforatum L.
Levels of hypericin were found to be unusually high in Nova Scotia biotypes and whether levels increased in late spring, when photosensitization most commonly occurs, and in a controlled-environment study,hypericin levels increased linearly with increasing temperatures.
Kaolin Affects Blueberry Maggot Behavior on Fruit
Oviposition trials with field-treated fruit showed that blueberries treated with Surround had fewer oviposition scars than the control, and this was more pronounced with weekly applications of Surround.

Performance of a Pyrethroid-Resistant Strain of the Predator Mite Typhlodromus pyri (Acari: Phytoseiidae) Under Different Insecticide Regimes
An organophosphate pyrethroid-resistant strain of Typhlodromus pyri Scheuten imported from New Zealand was reared on potted apple trees in an outdoor insectary, suggesting the ability of this predator to suppress their prey.
Effect of calcium salts on fortified apple juice
Purpose – This paper aims to examine the effect of selected calcium salts on the colour, clarity and calcium content of fortified apple juice in extended storage.Design/methodology/approach – Apple
Deployment and Utility of Traps for Management of Rhagoletis mendax (Diptera: Tephritidae)
Seasonal captures of adult blueberry maggot, Rhagoletis mendax Curran, on Pherocon AM traps increased l.8-fold when traps were protected from the prevailing winds compared with exposed sites, and
The objective was to determine if a sex pheromone occurs in Atractotomus mali, an economic pest of apple in the Annapolis Valley of Nova Scotia.
Field type, trap type and field-edge characteristics affect Rhagoletis mendax captures in lowbush blueberries.
Ripe blueberries and certain vegetation in forested edges affect fly distribution and probably maintain populations, and results may help to predict where controls for blueberry maggot should be targeted and suggest that management strategies focused on vegetative fields and field edges may be worthwhile.
Insectary Rearing and Initial Testing in Canada of an Organophosphate/Pyrethroid-Resistant Strain of the Predator Mite Typhlodromus pyri (Acari: Phytoseiidae) from New Zealand
A strain of Typhlodromus pyri Scheuten resistant to pyrethroids and to several organophosphate insecticides was imported into Nova Scotia, Canada, from New Zealand in 1988 and suppression of phytophagous mites continued in 1993 despite application of dilute cypermethrin in May of that year.
