Management options Late maturing varieties are much more likely to be infested with soybean loopers. Soybean looper is more difficult to control with insecticides than the cabbage looper. Although many pyrethroid insecticides are labeled for soybean looper control, they are not recommended because resistance is well documented. Indeed, use of pyrethroid insecticides can worsen infestations [ ].   The hypocotyl of different soybean genotypes was tested for its inducible phytoalexin (i.e. glyceollin or coumestrol) accumulation and its inducible soybean looper resistance in response to chemical elicitation. A very highly insect-resistant soybean genotype (PI ) produced significantly more phytoalexins than a relatively insect-susceptible one (Davis) in response to the same chemical Cited by:

From egg to adult, it will take anywhere from 25 to 30 days. Soybean loopers tend to spike in population in August and September. Soybean Looper Identification and Habitat. Identification. An adult soybean looper is a moth with brown spotted forewings that are 13 to 18mm long. Its entire wingspan is usually between 28 and 39mm.

Estimates of gene numbers indicate that the two parents differed by two genes for resistance to soybean looper. Heritability for resistance was estimated to be 63%; therefore, a breeder should be able to make progress by selecting in the F 2 or F 3 generations.

The soybean looper, Pseudoplusia includens (Walker) (Lepidoptera:Noctuidae), is the most abundant of the plusiine caterpillars attacking soybean over much of North and South America and all of Central America.

Loopers are migratory pests that sometimes show up late season and eat leaves, but not pods or seeds. Remember that the threshold for soybean loopers (and all defoliating pests) is 15% defoliation throughout the canopy (thresholds and defoliation guide here).

Loopers generally defoliate from the. The soybean looper is a caterpillar about 1 1/4 inches long that moves with the characteristic looping movement. It is a sporatic feeder on soybeans, usually found mid-July to mid-August. The larvae eat leaf tissue, leaving irregularly-shaped holes between the veins.
