The yellowstriped armyworm, Spodoptera ornithogalli, is an insect pest of tomato Solanum lycopersicum and pepper Capsicum annuum crops grown in hoop houses and greenhouses. The caterpillars larvae feed on tomato leaves and tunnel into the fruit of tomato and pepper Figs. Development time from egg to adult is between 30 to 90 days, dependent on environmental conditions such as temperature.
This destructive garden pest gets its name because it travels in small insect armies and consumes just about everything in its path. But some will eat anything green or red or yellow. In their larval stage, army worms attack a variety of crops as well as grasses, sometime moving en masse to new areas in a way that brings to mind, as its name suggests, an army on the march.

After a public meeting on Wednesday, farmers in the north Okanagan are organizing to combat a relatively new threat to their crops.

Zillinger estimates her farm has seen a 60 per cent hit to its income and will lose money this year as a result of the worm.
The distribution of this insect includes most of North America, Central and South America, and many Caribbean islands. As a pest, however, its occurrence is limited principally to the southeastern USA. A very similar species called western yellowstriped armyworm, Spodoptera praefica Grotelargely replaces S.

Figuring that volunteer bug identifier Bea in Ontario could figure out who he was I sent her the picture shown below:.
Spined soldier bug: Podisus maculiventrisa predatory and beneficial stink bug. Photo Marlin E. Objective This website is primarily concerned with pests and pest complexes in soybean and their management. In this website we are focused on soybean insect pests of the north central region of the United States.
A couple of recent reports reminded me that while our surveillance for soybean aphids and twospotted spider mites is ongoing, a few other creatures that enjoy soybeans also may make their presence known. Both Mike Roegge, Extension unit leader in Quincy, and Kevin Black, with Growmark, reported the appearance of thistle caterpillars the larval stage of the painted lady butterfly in a few soybean fields in Illinois. Their bodies are brown to black with a yellow stripe along each side of the body.
