Biotic Disorders Flashcards
One of a number of separate plants of certain obligate pathogens e.g. rust fungi or insects e.g., adelgids On which success of life stages develop
Alternate host
Disease caused by a fungus that induces expanding spreading necrosis of leaves and succulent shoots and produces asexual spores in small blister like fruiting bodies called acervulii
Anthracnose
One of a large group of invertebrates with jointed appendages segmented bodies exoskeletons (Insects, mites, and spiders)
Arthropod
Minute usually single celled organisms having a cell wall but no organized nucleus and reproducing by fission some species of plant pathogens
Bacteria
Insect of order Coleoptera That feeds and reproduces and galleries produced in the inner bark and bark-sapwood interface of trees
Bark beetle
Pertaining to living organisms
Biotic
Disorder caused by a living organism
Biotic disorder
Any disease or disorder regardless of the causal agent that rapidly the kills flowers, leaves, and young Stems That are typically retained i.e. not shared by the plant
Blight
Irregularly shaped necrotic area and leaf stem or fruit
Blotch
Any of several insects that tunnel into would potentially causing severe damage usually the larvae of certain moths and beetles
Bored
Discrete, localized, usually necrotic areas on stems, roots and branches; often sunken and discolored most canker disease is require laboratory isolation and microscopic and examination to positively identify
Canker
Larvae of insects in the order Lepidoptera
Caterpillar
Insect with mouthparts adapted for feeding by chewing e.g. Beetles and caterpillars
Chewing insects
Biotic or a biotic agent a disease or disorder or disease
Causal agent
Whitish or yellowish leaf discoloration caused by lack of chlorophyll; often caused by nutrient deficiency
Chlorosis
Disorder or disease occurring a recurring over a very long period of time typically multiple growing to seasons
Chronic
Conceptual model explaining development of specific recognizable disorders resulting from the interaction a predisposing inciting and contributing factors that act in succession over a prolonged period of time resulting in progressive deterioration in tree health.
Decline disease
Loss of leaves from the tree or other plant by biological chemical or mechanical means as opposed to natural shedding
Defoliation
Result of interaction overtime of a pathogen or abiotic agent with a susceptible host and a Conducive environment to interfere with one or more physiological functions or structures
Disease
Combination of factors involved in development of a disease
Disease complex
Conceptual model showing three factors required for plant disease susceptible host pathogen or abiotic agent and a conducive environment
Disease triangle
Downward twisting curling or bending of a leaf blade or shoot that may result from disease or herbicide injury
Epinasty
Mites in the family Eriophyidea; Typically smaller than other lights requiring higher magnification to see an afternoon decent development of life goals
Eriophyid mites
Fecal material and or wood dust or shavings produced by insects
Grass
Reproductive structure of a fungus that usually develops in diseased Tissues the presence of certain species may indicate DK and a tree mini fruiting bodies are small and can only be seen with a hand lens and require microscopic examination to determine the species of fungus present
Fruiting body
Heterotrophic parasitic or saprophytic absorptive Organisms from the kingdom fungi including you smalls those that for mushrooms or conchs this months in rust usually Multicellular and filamentous fungi like the chlorophyll and vascular tissue of plants and reproduce asexually or sexually to form spores often born in various types of fruiting bodies
Fungi
Abnormal plant structure of the develops in the cells tissues or organs of a plant only when it is colonized by certain parasitic organism such as bacteria fungi nematodes mites or insects.
Hall
Complex of tunnels created by insects and plant tissues for feeding reproduction and shelteringThe pattern created by galleries can sometimes be used for pest identification
Galleries
Exultation of sub gum or resin often in response disease or insect damage
Hummus is
An animal that feeds primarily on plants
Herbivore
Sugary substance excreted by certain insects including aphids in some scales when feeding on plants
Honeydew
Capable of being spread from plants to results and infection of other plants or organisms
Infectious
Presence of a pest population on a house plant or group of plants
Infestation
Part of a pathogen that may enter the host or germinate to produce a structure that enters the host to cause disease
Inoculum
Substances man-made or natural occurring in insects that affect growth and development of insects
Insect growth regulator’s
Stage of growth between moles of an amateur insect larva
Instar
Amateur life stage of an insect between the egg and the pupa stage
Larva
Type of insect with a larval stage that feeds between leaf structures
Leaf miner
Local area of disease or damaged tissue
Lesion
Series of stages that completeThe life of an organism resulting in reproduction
Lifecycle
One of multiple phases in the growth and development of an organism
Life stage
Small step sucking scale like insect coated with a white powdery wax
Mealybug
Biological transformationIn the lifecycle of an organism going from an immature to an adult stage
Metamorphosis
A flowering green plant that penetrates in parasitizes the vascular system the trees two distinct groups are the doors in the leafy mistletoe
Mistletoe
It’s more often my new anther pods in the class Arachnida to let me feed on plants other lights are insects
Mite
And insects and other arthropods part of the metamorphosis process in which the old cuticle of the exoskeleton of shed after new cuticle is formed
Molting
Network Or mass of filamentous cells (hyphea) that make up the vegetative body and fruiting bodies of fungus
Mycelium
Localized general death of cells are parts of a living organism
Necrosis
Small often microscopic unsegmented roundworm many are beneficial organisms but Some vera plant to choose to cause death or spread viruses
Nematode
Immature form of an insect with incomplete development resembling a smaller version of the adult without wings
Nymph
Laying of eggs by insects
Ovipositing
Organism living in or on another living organism during it’s immature stage killing sterilizing and or consuming the host
Parasitoid
Causal agent of disease usually refers to micro organisms e.g. bacteria fungus or virus
Pathogen
Organism including weeds, insects, bacteria or fungi that is damaging noxious or a nuisance
Pest
A biological stage of development of an organism that may be associated with other biological events such as insect hatching or plant flowering
Phenological stage
Chemical substance produced by an animal usually in reference to insects that serves as a method of communication with other individuals of the same species
Pheromone
Bacteria like form phloem-inhabiting micro organisms without a cell wall or organized nucleus that cause yellow diseases in plants
Phytoplasmas
Insect with mouthparts adopted for feeding by piercing soft tissues and sucking fluid contacts
Piercing sucking insects
Tubular structure is formed on the bark around insect entrance holes can be made of resin, boring dust and or frass usually associated with conifers
Pitch tubes
localized or general death of cells or parts of a living organism
necrosis
