  • Injury is the effect of insect on plant.
  • Cucumber mosaic virus: >60 aphid species are capable of transmitting CMV in nonpersistent virus – virus is acquired within 1 min of feeding but can be transmitted within a short duration of time (stylet-borne inoculum)Potato virus Y: aphids can acquire the virus in less than a minute and has to be transported very quickly to a healthy plant in a minute or so. Aphids may retain the virus for 24 h.
  • Define the problem: Record the normal & abnormal charactersKeep written notes & take pictures (blogging?)Examine entire plant in its ecosystemLook around: is something affecting one plant or a group of plants?Look for patterns:Nature is random!If patterns exist on plant or a group of plants…abiotic problem? (e.g., herbicide injury, storm injury to plants, etc.)Biotic sources affect plants randomly (e.g., insect, diseases)Biotic problems change location between yearsScouting procedure:If you have found the problem, mark the problem area with sticks, garden stakes, tall flags, etc.Familiarize yourself with sampling techniques and sample preparationTake a closer look at plants, uproot plants if feasibleAsk the experts before spending money on control!Delineate time-development:Biotic problems may spread slowly in an area and a pattern may appearAbiotic problems develop faster and patterns are obviousKeep an eye on the marked area and sample frequently to be able to “encounter” the problem (random) Determine the cause of injury:Think broadly >> narrow down to few causes ORUse the process of elimination to arrive at a solutionUse all resources you have to ID insects, many on the webFind the economic threshold: doing nothing is also OK
  • Trends in FAW population were stronger than BAW seen before. FAW pressures were high in all parts of AL. There were at least two generations detected one month apart of FAW in north central AL. Three peaks could be detected one month apart in south AL along the Gulf Coast. Impact of weather parameters was also stronger on FAW populations than BAW.

    LET’S TAKE THE PRE-TEST FIRST!
  • 9. Insect Form & Function
    This sign indicates study of real insect specimen using a digital microscope (Dino-Lite Pro)
  • 10. Fun Facts about insects
    Insects have been around for at least 350 million years
    Over 900,000 described species (75% of all animal species)
    U.S. has about 91,000 described species
    Less than 1% of these are considered pests
    Four largest insect orders: beetles (Coleoptera), flies (Diptera), ants (Hymenoptera), moths (Lepidoptera)
  • 11. Why are INSECTS so successful?
    Small size, cryptic in nature
    Small food requirement
    Rapid and prolific reproduction
    Parthenogenesis
    Grows by molting (control over growth rate)
    Life stages feed on different substrate
  • 12. Characteristics of arthropods
    Segmented bodies and jointed appendages

    Characteristics Insects:
    Three body regions (head, thorax and abdomen)
    Six legs or less or zero (NEVER more!)
    Grasshopper specimen
  • 13. Insect Exoskeleton
    Insects have a cuticle, cuticle has chitin
    Exocuticle
    Epicuticle (topmost)
    Chitin molecules interlink to provide strength!
    Endocuticle
    Hard cuticle of a cockroach
  • 14. Insect Growth
    Insects need to shed (molt) old skin to grow in size.
    The period between molts is called an instar.
    Most insects have 4–8 instars before becoming adult.
    Cicada nymph molts into an adult
  • 15. Insect Growth
    Metamorphosis:drastic change in shape and form for growth and development.
    Two types: complete and incomplete.
    The stage of development of an insect will affect insecticide efficacy:
  • 16. Complete metamorphosis

  • Steps to
    Intelligent Plant Management
    • Choose the right plant for right season
    • 71. Choose the right plant for location
    • 72. Plant vigorous stress-free plants
    • 73. Maintain good cultural practices (sanitation, chemical applications, weed control)
    • 74. Pin-point stress & take action early
    • 75. Stressed plants will be overcome by insects
    • 76. Manage insects by Integrated Pest Mgmt
  • Integrated Pest Management
    Basic concept, status of IPM in AL, implementation
  • 77. What is IPM?
    • “Integrated pest management (IPM) is a threshold based decision management system which leads to judicious use of multiple pest control tactics.”
    • 78. IPM is currently insecticide-intensive…
    • 79. 70% area under IPM yest major losses occur due to:
    • 80. Lack of early detection of insects
    • 81. Insecticide resistance by misuse
    • 82. Loss of natural control with insecticides
  • Need for IPM
    • Loss of tomatoes in the absence of insecticides: 95% (AL)*
    • 83. Nationally, average gain from IPM is $19 for every dollar spent (field crops)*
    • 84. There is increasing demand for organic crops…
    • 85. Insecticide use in AL is reducing, 1992-2002:
    • 86. Asparagus (-30%)
    • 87. Green peas (-73%)
    • 88. Green beans (-36%)
    • 89. Tomatoes (-20%)
    *L. Gianessi, 2009. Crop Protection Research Institute.
  • 90. IPM in home & garden
    Remove abiotic stresses
    Conserve natural enemies (habitat)
    Correctly identify insect pest
    Biological control agents (microbials)
    Cultural tactics – variety, rotation, trap crop
    Chemical insecticides
    Correct insecticide delivery system: correct application rate, timing, coverage
  • 91. NE Conservation System
    Grassy buffers
    Grassy buffer zone in permanent ecosystems
    Grass shelters natural enemies
    Many night-feeding insects hide in grass during day…treat the edges!
    Sample in grass and keep it under control
    Grassy buffer zone in temporary agroecosystem
  • 92. Trap cropping arrangements
    Perimeter Trap Cropping
    Trap crop (squash)
    Trap crop = early planted squash, apply insecticide on borders

    Main crop
    (watermelon, cantaloupe, cucumber)
  • 93. Trap cropping arrangements
    Row Trap Cropping (contd.)
    Plant trap crop (alfalfa) in rows within the main crop (strawberry) & a using vacuum!

    (34 rows)
    Strawberry
    (34 rows)

    Alfalfa
  • 94. Recommendations for trap cropping
    Try it on a small scale to gain confidence
    Integrate with biological/chemical i-cides, pheromone trapping, etc.
    Trap cropping can manage 1-2 insect species
    Works great against sucking pests (plant bugs) and slow fliers (beetles)
    Spray only the trap crop…reduce cost
  • 95. Alternative Insecticides for Gardeners
    Use them in rotation:
    Thuricide, Dipel (Bt)
    M-pede (soap)
    Safer pyrethrin
    Oils (with caution!)
    Contact a nursery for supplies & purchase early
    Do not use unlabeled insecticides (e.g., RTU home pesticides)
    Always read the label!
  • 96. Toxicity of Some Insecticides (General Use Pesticides)
    Ref.: “General use insecticides for home gardening” by Dr. RicBessin (UK)
    Rule 1: Higher the LD50 safer will be the product!
    Rule 2: Products containing highly toxic AI have very low % chemical.
  • 97. Decision making in IPM…
    Insect detection & monitoring
    Insect identification
    Population pressure
    Economic threshold
    Make treatment decision
    Choosing right insecticide
  • 98. Monitoring insects with TRAPPING DEVICES
  • 99. What are insect pheromones?
    Pheromones are chemicals released into environment in small amounts by insects.
    Pheromones are species specific, stimulates opposite gender.
    Male moths detect pheromones with antennae.
    Synthetic sex pheromones are manufactured & used as lures.
  • 100. Types of Insect Traps
