Greenhouse horticultural production currently represents an important and growing sector of Canada's food and plant production systems. since 2006,the value of greenhouse vegetable crops in Canada exceeds that of field grown crops,signaling an important shift in the way food is cultivated in the country. While many factors have contributed to this change,a major area of innovation includes the discoveries and advances made in the development of commercial greenhouse production systems as well as the integration of biological control strategies for sustainable pest management. With this focus,this review offers a brief overview of the Canadian greenhouse industry,including a descriptive list of commonly used biological control organisms,as well as the role Canadian research has played in the development of these agents. We also address the threats that Canadian greenhouse producers face by invasive pests and the complications these have created for the commercialization of novel biological control agents. This information may serve as a guide for the development of parallel technologies and tools in other parts of the world where greenhouse production is expanding.

There is a strong evidence supporting the hypothesis of synaptic dysfunction as a major contributor to neural circuit and network disruption underlying emotional and mood dysregulation in psychiatric disorders(simmons et al.,2024).Diverse sets of distinct molecular signaling pathways converge on the synapse to regulate synaptogenesis,synaptic function,and synaptic plasticity in brain regions and circuits through complex interactions organized by numerous multivalent protein scaffolds,including the family of proteins known as A-kinase anchoring proteins(AKAPs).

Rockbursting in deep tunnelling is a complex phenomenon posing significant challenges both at the design and construction stages of an underground excavation within hard rock masses and under high in situ stresses. While local experience, field monitoring, and informed data-rich analysis are some of the tools commonly used to manage the hazards and the associated risks, advanced numerical techniques based on discontinuum modelling have also shown potential in assisting in the assessment of rockbursting. In this study, the hybrid finite-discrete element method(FDEM) is employed to investigate the failure and fracturing processes, and the mechanisms of energy storage and rapid release resulting in bursting, as well as to assess its utility as part of the design process of underground *** the calibration of the numerical model to simulate a deep excavation in a hard, massive rock mass, discrete fracture network(DFN) geometries are integrated into the model in order to examine the impact of rock structure on rockbursting under high in situ stresses. The obtained analysis results not only highlight the importance of explicitly simulating pre-existing joints within the model, as they affect the mobilised failure mechanisms and the intensity of strain bursting phenomena, but also show how the employed joint network geometry, the field stress conditions, and their interaction influence the extent and depth of the excavation induced damage. Furthermore, a rigorous analysis of the mass and velocity of the ejected rock blocks and comparison of the obtained data with well-established semi-empirical approaches demonstrate the potential of the method to provide realistic estimates of the kinetic energy released during bursting for determining the energy support demand.

Florida populations of the eastern tiger swallowtail butterfly, Papilio glaucus L., have unique morphological features and ecological adaptations that have contributed to their subspecies status （P. g. rnaynardi Gauthier）. We describe geographically unique abilities for detoxification of Carolina willow, salix caroliniana Michx. （salicaceae）, for several Florida populations of P. g. maynardi. Of all the approximately 570 worldwide species of the Papilionidae, such salicaceae detoxification abilities exist only in the allopatric North American western and northernmost species （P. rutulus Lucas, R eurymedon Lucas and P. canadensis Rothschild ＆ Jordan）. Females of P. glaucus collected from populations in southeastern UsA were examined for oviposition preference in 5-choice assays, and displayed a low preference for salicaceae （〈5%）, but larvae from Florida populations exhibited a high survival （〉 60%） on these plants. Detoxification abilities have previously shown to be autosomally inherited, and can be transferred via natural or hand-paired interspecific hybrid introgression. However, these Florida populations are at least 700-1 500 km from the nearest hybrids or the hybrid species, 17. appalachiensis Pavulaan ＆ Wright, which possess these detoxification abilities. In any case, the Z （ = X）-linked oviposition preferences for salicaceae are lacking in these Florida populations, illustrating genetic independence ofoviposition preference determination and larval survival/performance abilities. The origins of detoxification abilities are unlikely to be due to recent climate-driven introgression, and may represent ancestral trait carry-overs from interglacial refugium populations of the Pleistocene epoch.
