Melanophila consputa Lec. Western pine beetle Dendroctonus brevicomis Moisture Forest insects are affected directly by moisture and indirectly by its effect upon their host Light Light plays an important part in regulating the activities of various insects. Trees exposed to the full sunlight are more susceptible to attack by certain flatheaded borers. Many moths are strongly attracted to light.

Wind is relatively unimportant in cross-pollination of sunflower. Some of the older open-pollinated varieties such as Peredovick set only 15 to 20% of seed without pollinators, whereas many hybrids set 85 to 100% seeds without pollinators. Insect pests have become major potential yield-reducing factors in sunflower production in the northern Midwest (Table 4). Insects specific to sunflower that feed on the heads include the larvae of three moths; sunflower moth, banded sunflower moth and sunflower bud moth. Sunflower midge has caused widespread damage in some years. Sunflower headclipping weevil, sunflower beetle, sunflower maggot, wireworm, grasshopper, cutworm, sugarbeet webworm, ragweed plant bug, woolybear and painted.lady caterpillar have caused occasional damage to sunflower. Adults of insect pests of other crops (such as corn rootworm beetle and blister beetle) can be found as pollen feeders on sunflower
