19. Correct. They spin silken shelters to protect themselves while hibernating over winter.

20. Wrong. They like to keep warm and safe in the cold winter months.

21. IDW is…?  The second largest defoliator in BC? The second largest defoliator in BC?  The least damaging defoliator in BC? The least damaging defoliator in BC?  The largest defoliator in BC? The largest defoliator in BC?  The only defoliator that feeds on deciduous in the winter? The only defoliator that feeds on deciduous in the winter?

22. Give yourself a pat on the back. IDW are the most damaging in BC; severe outbreaks can last up to 25 years.

23. Sorry, try again… Severe infestations fluctuate with weather and are of great concern to BC forests.

The eggs and larvae look exactly the same due to incomplete metamorphosis.

25. Correct. There are 4 distinguishable white dots on each segment of the larva; the eggs look like fish scales on the underside of the needle.

26. Try Again. Good things come in 4.

34. Right OnRight On! IDH has a black thoracic shield, and a black & brown head.

35. Ooooh, try again… The larvae are naked with a greenish/olive skin tone.

36. What are the IDHs’ 2 partners in crime?  Coast Hw Looper: Interior Mountain Pine Beetle Coast Hw Looper: Interior Mountain Pine Beetle  Coast Hw Looper: Interior Hw Sawfly Coast Hw Looper: Interior Hw Sawfly  Coast Hw Sawfly: Interior Hw Looper Coast Hw Sawfly: Interior Hw Looper  Coast Black Headed budworm: Interior Fd Tussock moth Coast Black Headed budworm: Interior Fd Tussock moth

37. Top Shelf. 50% reduction in growth for up to 4 years after outbreak.

38. Try Again Both Hw Looper and Hw Sawfly are its partners in crime.

39. Hw Looper prefers to relax in …?  Coast – high elevations? Coast – high elevations?  Coast – low elevations? Coast – low elevations?  Interior – high elevations? Interior – high elevations?  Interior – low elevations in the wetbelt? Interior – low elevations in the wetbelt?

40. Wrong. IDL likes getting’ low…

41. Stellar. Actually, there were 2 correct answers: IDL prefers wet, poor sites at low elevations in both the interior & coast

42. What describes IDL’s table manners?  Wasteful Wasteful  Clean Clean  Glutinous Glutinous  Territorial Territorial

43. Good Job IDL are considered to be wasteful feeders and create a zig zag pattern on the landscape.

44. Better Luck Next Time… Look for forest floor that is littered with needles…

45. Which feeding pattern best describes the feeding pattern of IDL?  Patchy Patchy  Zig-Zag Zig-Zag  A bite here and there… A bite here and there…  Perimeter feeding Perimeter feeding

46. Neato Gang!! Zig-Zagging is fun.

47. Shame on you… …Think Charlie Brown’s sweater pattern.

48. Top kill caused by IDL can damage up to how many meters of Hw crown?  0.5 meters 0.5 meters  1.0 meters 1.0 meters  10 meters 10 meters  3.0 meters 3.0 meters

49. OUI, OUI Heavy feeding at the top of the tree can result in mortality after only 1 year of severe defoliation.

50. No, good try though. More than 1.0 meter, but less than 5.0 (doesn’t that sound like something Doug would say?)

51. At what stage is the Gypsy moth most mobile?  Egg Egg  Larva Larva  Adult Adult  Grub Grub

52. Eureka The egg mass, a.k.a hitch- hikers, travels long distances by attachment to vehicles and firewood.

53. Tough One. Hint: “Remove Before You Move”

54. Scenario: You’re cruisin’ down the highway and you notice defoliation along “elevation bands”, what defoliator should first come to mind?  IDL IDL  MPB MPB  WTF WTF  IDW IDW

55. I’m proud of you. IDW causes distinct banding along elevations.

56. Maybe next time…. I D rive W est

57. When you see this image, what defoliator do you think is responsible?  IDW IDW  IDT IDT  IDL IDL  IDH IDH

58. DYN-O-MITE! The Tussock moth damage results in distinct patches of defoliation.

59. Ces’t la vie… IDW damage happens along elevation bands…which one causes damage in patches?

60. Which defoliator will eat almost anything?  Gypsy moth Gypsy moth  Western spruce budworm Western spruce budworm  Douglas-fir Tussock moth Douglas-fir Tussock moth  Eastern tent caterpillar Eastern tent caterpillar

61. You’ve got it made. The Gypsy moth enjoys a good buffet of 300+ species.

62. Oops… Hint: It rhymes with tipsy.

63. How would you manage for Gypsy moth?  Btk only Btk only  NPV only NPV only  NPV, ‘Gypchek’, Btk and Dimilin NPV, ‘Gypchek’, Btk and Dimilin  Just walk away and hope for the best… Just walk away and hope for the best…

64. You’re right on track Dimilin inhibits ‘chitin’ growth which inhibits molting.

65. Let’s be honest here… GYPCHEK yo’self before you wreck yo’self

66. What are the 2 main management activities that should always take place while dealing with defoliators?  Permanent and annual pheromone trapping Permanent and annual pheromone trapping  Annual spring applications of NPV and Btk Annual spring applications of NPV and Btk  Sanitation and early harvest of infected stands Sanitation and early harvest of infected stands  Surveys and annual overviews Surveys and annual overviews

67. Tremendous! Annual precautions are the best bet.

68. Negative. Hint: I hope you enjoy the paperwork

69. What is the most common ‘short term’ management approach to defoliator outbreaks?  NPV NPV  Btk Btk  NPV and Btk NPV and Btk  Pheromone trapping Pheromone trapping

70. StupendousStupendous. Btk is the most common short term management tactic for IDW, IDH, & IDL; it decreases the extent of damage caused in one season.

71. Try again… NPV decreases dispersal and spread over large areas.
