The legs are white. The abdomen is mostly brown except for the tail segment, which is white and has a large fluffy tuft. Adults are not active during daylight hours and eggs are laid only at night. It lays tiny eggs in small clusters on growing areas of the plant, such as flowers, shoots, and new leaf buds.
worm' is a large, blueish worm species thought to be native to Eastern Asia, now widely distributed around the world (along with several other lumbricids). In some areas where it is an introduced species , some people consider it to be a significant pest for out-competing native worms.
They are typically harmless to healthy plants - and humans - but can inflict extensive damage to seedlings; their presence can indicate more serious problems. In houseplants , the presence of sciarids may indicate overwatering; they may be feeding on roots that have been immersed in water too long and are thus rotting, or the gnats may be ...
Worm grunting is the act of vibrating a wooden stake that has been driven into soil to bring worms to the surface where they can be collected by hand. [33] Another way to remove invasive earthworms are mustard pours. Mustard pours are 1 gallon of water and 1/3 cup ground yellow mustard seed mixed together.
The female can lay a maximum of about 1,000 eggs in her lifetime. She can lay 100–400 eggs per night, with an overall average of 150. [9] [11] The number of eggs females can lay is positively correlated with their pupal weight. [4] African armyworms primarily lay their eggs in clusters on the lower side of leaves.
Both overwinter in the egg stage in the soil. Eggs, which are deposited in the soil during the summer, are American football-shaped, white, and less than 0.004 inches (0.10 mm) long. Larvae hatch in late May or early June and begin to feed on corn roots. Newly hatched larvae are small, less than .125 inches (3.2 mm) long, white worms.
Cutworms are moth larvae that hide under litter or soil during the day, coming out in the dark to feed on plants. A larva typically attacks the first part of the plant it encounters, namely the stem, often of a seedling, and consequently cuts it down; hence the name cutworm. Cutworms are not worms, biologically speaking, but caterpillars.
Spodoptera litura, otherwise known as the tobacco cutworm or cotton leafworm, is a nocturnal moth in the family Noctuidae. S. litura is a serious polyphagous pest in Asia, Oceania, and the Indian subcontinent that was first described by Johan Christian Fabricius in 1775. [1]
