Bagworm is causing serious violate to evergreens in southeast Nebraska. Native to the United States and found surrounded by eastern Nebraska, bagworm feeds on the foliage of adjectives evergreen hosts including Juniper (cedar), arborvitae, pine, and spruce as well as deciduous trees and shrubs.
Bagworms over-winter as eggs in bags fastened to twigs of the host tree. Eggs hatch surrounded by late May or untimely June as caterpillars and begin to spin tiny (1/4 inch) protective cases or lots around themselves. These bags are made of silk and leaf/needle fragments that grow to two inches within length by the end of the summer and somewhat resemble Christmas tree ornaments flaccid from a limb. Larvae nurture until late August or precipitate September when the males emerge and mate with the wingless females through the pod entrance. Female moths deposit their eggs then die, never going away the bag. Each feminine can produce 500-1,000 eggs. About half the plenty on a host plant will contain female bagworms while the partner contain males.
Heavy infestations of bagworms are capable of completely defoliating an evergreen i.e. severely stressed or even killing the tree if control measures are not taken. Bagworms on evergreens are especially wounding because destroyed foliage does not regenerate. Infestations on deciduous trees and shrubs are not as serious since these plants have the handiness to grow new leaves.
On smaller trees and shrubs, bagworm can be controlled by removing or hand-picking adjectives the bags during the winter and spring prior to the egg hatch contained by late May. Bags should be destroyed by crushing or immerse in soapy river so that the larvae cannot return to the host plant. For larger plants or infestations, insecticides are decisive if applied during early stages of bagworm nouns. For most effective control and prevention of precipitate season damage, apply sprays from mid to unpaid June. Some options for insecticides include Sevin, Malathion, Diazinon, Orthene, Dipel, and Dursban. As other, read, understand, and follow sticky label directions before using.
