There are several species of moths whose caterpillars are significant pests on agricultural crops. While there are natural predators, some are unwilling hosts for parasites. Some parasitoid wasp species contribute to biological control of these caterpillar pests by laying eggs inside live caterpillars.Dataset Type: OccurrenceSpecimen Type: Preserved specimens

The Forest Health Section currently monitors for two insects using pheromone traps. Pheromones are the chemical signal insects created by the insect for communication. Pheromones are used for numerous types of communication. In some species they are used to call other insects together (e.g. aggregation), in some they are used to repel others (e.g. anti-aggregation), in most insects these chemical signals are very specific and unique. Scientists have been able to identify and reproduce these chemicals in many species, allowing us to monitor species presence/absences and relative abundance in pest management. For botha) spruce budwormb) hemlock looperthe sex pheromone is emitted by the female to attract male moths. The Province places traps containing pheromone lures for both throughout the province.At the end of the season, the number of moths found in the traps give an indication of population trends for that season. These result support additional monitoring efforts such as the SBW fall population forecast. The pheromone traps are useful tools, but they only provide a partial picture on populations because in the case of both spruce budworm and hemlock looper the pheromone attract the male moths only.Each marker on the spruce budworm map represents three traps hung in a 40m spacing array, the value posted is the average of the three traps counted.

Les phéromones constituent le signal chimique que les insectes créent pour communiquer. Les phéromones servent pour de nombreux types de communications. Pour certaines espèces, elles servent à rassembler d’autres insectes (p. ex., agrégation); pour d’autres, elles servent à repousser les autres (p. ex., anti agrégation). Chez la plupart des insectes, ces signaux chimiques sont très spécifiques et uniques. Les scientifiques ont réussi à déterminer et reproduire ces signaux chimiques avec nombre d’espèces, ce qui nous permet de surveiller la présence

Every year, since 1967, the Ministry of Natural Resources and Forests (MRNF) has been conducting an aerial survey and since 2024, with the acquisition of satellite imagery, the Ministry has detected some damage caused by the main insects and diseases that attack trees. This fact sheet focuses exclusively on data concerning damage caused by forest livery. The data is updated annually only in case damage is observed.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

Phytoplankton species abundance (cell/L) and oceanographic conditions (temperature, salinity, chlorophylle-a (mg/m³) for some years and nutrient content (mmol/m³)) at stations of the Harmful Algae Monitoring Programme (HAMP) from1994 to 2016.The layer presents the station positions of the HAMP. Two files are attached to each station: one containing the cell counts and the second the oceanographic conditions.PurposeThe summer growth of many toxic and harmful microalgae species poses a serious threat for the public health and commercial or recreational exploitation of some marine species.The Department of Fisheries and Oceans (DFO) initiated the Harmful Algae Monitoring Programme (HAMP) in 1989 in order to complete the monitoring program for paralytic shellfish poisoning (PSP). Under the responsibility of Maurice-Lamontagne Institute scientists, the HAMP is to monitor, by means of a coastal station network, the natural occurrence of toxic and harmful algae in the St. Lawrence in order to determine their spatio-temporal distribution and the environmental conditions leading to their bloom.The network is made up of 11 coastal stations which are sampled every week from April to November and which are established along Quebec eastern shores. It extends from Tadoussac to Tête-à-la-Baleine on the St. Lawrence north shore and from Sainte-Flavie to Carleton on the south shore along the Gaspé peninsula. Another station is located in Havre-Aux-Maisons, Magdalen Islands.The HAMP was discontinued in 2010 but opportunistic samplings are still done at some stations.Additional informationThe sampling and analysis protocol is described in details in the following publication apart from the fact that the number of identified and counted species significantly has been increasing with time. Phytoplankton samples are preserved in a lugol solution.Blasco D., M. Levasseur, R. Gélinas, R. Larocque, A.D. Cembella, B. Huppertz et E. Bonneau.1998.

Shows areas where forest insect pests have damaged or killed trees by defoliation, foliage mining and wood boring. Tree mortality rarely occurs as the result of one year's infestation, but from the result of several consecutive years of infestation and other contributing factors affecting weakened trees (e.g., fungal invasion). The Government of Ontario tracks forest damage events to help proactively manage the detrimental effects to our forests.   We monitor the threat and spread of invasive forest pest insect species in Ontario. The data is also important to the Forest Management Planning process in calculating timber volume loss within affected areas This product requires the use of geographic information system (GIS) software.

An Agreement Forest Area is a polygon feature that identifies an area of forested private land governed by a Forest Management Agreement. Private companies have agreed, through negotiated agreements with the ministry, to carry out planning and all operational timber management, except protection operations (for example, insect and disease pest control). We are no longer updating this data. It is best suited for historical research and analysis.

The Forest Protection Area dataset is comprised of all the polygons that represent the administrative areas established by Forest Protection, Forestry Division of Alberta Agriculture and Forestry concerned with the prevention and control of damage to forests from fire, insects, disease and other harmful agents.
