Molluscicides (/ m ə ˈ l ʌ s k ɪ ˌ s aɪ d s,-ˈ l ʌ s-/) [1] [2] – also known as snail baits, snail pellets, or slug pellets – are pesticides against molluscs, which are usually used in agriculture or gardening, in order to control gastropod pests specifically slugs and snails which damage crops or other valued plants by feeding on them.
D. dipsaci is a microscopic worm about 1.5 mm long. It penetrates plants from either the soil or infested planting material and occasionally from seeds. They live between the cells of onion or garlic leaves and between the scales of the bulbs where they feed on cell sap and multiply.
The larvae damage bulbs of onions, garlic, chives, shallots, leeks, and flowering plants. The first generation of larvae is the most harmful because it extends over a long period owing to the females' longevity and occurs when the host plants are small. Seedlings of onion and leek can be severely affected as can thinned-out onions and shallots. [3]
There’s an invasive species of worm making itself known in Texas once again—the hammerhead flatworm. These worms are toxic, hard to kill, and dangerous to native critters like earthworms, but ...
The hunter either watches the bait from point within firing range or stalks the animal if it has come for the bait during the night. [citation needed] In areas where bears are hunted, bait can be found for sale at gas stations and hunting supply stores. Often consisting of some sweet substance, such as frosting or molasses, combined with an ...
Insect traps are sometimes used in pest management programs instead of pesticides but are more often used to look at seasonal and distributional patterns of pest occurrence. This information may then be used in other pest management approaches. The trap mechanism or bait can vary widely. Flies and wasps are attracted by proteins.
The screw-worm fly was the first pest successfully eliminated from an area through the sterile insect technique, by the use of an integrated area-wide approach.. The sterile insect technique (SIT) [1] [2] is a method of biological insect control, whereby overwhelming numbers of sterile insects are released into the wild.
Subsequent to this, the anthelmintic activity was isolated and identified as a family of closely related compounds. The compounds were finally characterized and the novel species that produced them were described by a team at Merck in 1978, and named Streptomyces avermitilis (with the adjective probably intended to mean that it kills worms).
