Curries often result in stinky pee because of a body’s inability to filter out the cuminaldehyde in cumin and the linalool in coriander. Tomatoes and Asparagus are good plants to grow near one another due to the fact that tomatoes keep the asparagus beetle away and asparagus repels certain types of root nematodes that are bad for tomatoes. Adult beetles are only 1/4 inch long. Others are beneficial due to their use in biocontrolof invasive weeds. Chronological Index to the Field Station Bulletin, spear with a bunch of eggs glued to it or a smear of, lays its eggs in rows of 3 to 8 on the new spears, leaves or flower buds, The young hatch within a week and start feeding. Asparagus Beetles Crioceris species; Family: Chrysomelidae There are two species of beetles that attack and cause economic damage to asparagus in New York. These beetles, which live for one to two months, can feed on a multitude of plant species, including asparagus. The length of beetles varies from 5 to 6.5 millimeters. Common Asparagus Beetle: Crioceris asparagi (L.) Common asparagus beetle: adult. Female Chrysomelids have the ability to favor the sperm of a suitor by keeping eggs fertilized by a male if they like the cut of his jib and ejecting the sperm of previous males. Crioceris, or asparagus beetle, is a genus of the family Chrysomelidae of beetles. It lays one egg at a time on the leaves; the larvae hatch, head for the fruits, and burrow inside. Control asparagus beetles in the fern season. They may scoot over and hide on the other side of the stalk, may do the classic Chrysomelid drop to the ground, or may resort to secretions from defensive glands. The asparagus beetle and the lady bug look similar; the lady bug is about 1/4 inch or even smaller and rounder but the asparagus beetle is elongated. The common is, well, more common. Genus: Asparagus Tourn. One species of asparagus beetle is blue-black; another is orange with black spots. It uses its antennae and/or ovipositor to detect hosts that are already parasitized and doesn’t waste its time on them, and it targets only the common asparagus beetle (alas for the 12-spotted; a different species in the wasp’s genus goes after them). Asparagus beetles are an annual insect pest of asparagus. Common asparagus beetle. Order - Beetles - Coleoptera. Beetles and larvae … They’re not the only ones who are waiting. The common is, well, more common. Asparagus consisting of three hundred species is a large genus belongs to liliaceae family, of which twenty are. Asparagus beetles, in the leaf beetle family (Chrysomelidae), are asparagus specialists. The insects feed on the shoots as they develop, causing them to bend in the direction in which the feeding damage occurs. Their diversity has run parallel with that of the Angiosperms. They’re lovely little beetles, and two species grace our area, the Asparagus/common asparagus beetle ( Criocerus asparagi) and the Spotted/12-spotted asparagus beetle ( Crioceris duodecimpunctata) (yes—Latin for “12-dotted”). The colour of head, pronotum and elytra is reddish orange, while the scutellum is black. The common asparagus beetle is the first to wake up, and it also feeds on the lacy leaves, which can defoliate and weaken the plant, a perennial (no leaves = no photosynthesis = no food storage) and can make it susceptible to fungal infections. ex L. Asparagus officinalis L.; Asparagus officinalis has been cultivated and harvested from the wild for thousands of years and has become an economically important crop. Common asparagus beetles have several arrows in their quivers. The adult beetles are red, yellow, and black in colour and about 7 mm (almost 0.3 inch) long. Some studies have found low genetic diversity among groups of isolated Chrysomelidae, and use Wolbachia species as a genetic marker. The spotted asparagus beetle, Crioceris duodecimpunctata, looks very similar in appearance, but is not related. Temperatures can only get so low before beetles begin to die so beetles seek out shelter so they are protected as much as possible from freezing temperatures. Asparagus beetles, in the leaf beetle family Chrysomelidae, are asparagus specialists. Compared to most other vegetables, asparagus is relatively winter hardy, with higher heat, drought, and salt tolerances. A Asparagus Beetle Crioceris asparagi. They’re lovely little beetles, and two species grace our area, the Asparagus/common asparagus beetle (Criocerus asparagi) and the Spotted/12-spotted asparagus beetle (Crioceris duodecimpunctata) (yes—Latin for “12-dotted”).

This species is less destructive than the common asparagus beetle because only the adults feed on asparagus plants. Adults are bright orange with six small black spots located on each wing cover. Both species overwinter as adults in hollow asparagus stems, or under leaf litter, garden debris, or loose bark—that way, when the sun warms the soil and the asparagus spears poke their heads up in spring, the beetles are already in the neighborhood.

The 12-spotted gets out of the gate a little later in spring, and it also eats the spears and leaves, but its larvae concentrate on the fruits and don’t damage the plant (not a problem unless you raise asparagus for seed, and most growers don’t—they’re in it for the vegetable and they cultivate higher-yield, (seedless) male plants). When thinking of asparagus pests, we normally worry about early season feeding on developing spears. The name is neo-Latin from Greek κριός, ram and κέρας, horn. If you’re growing asparagus in your home garden, the asparagus beetle is a pest you will be all too familiar.

You may spot damaged spears before you see the pests themselves. However, late summer and fall scouting is important to get ahead of spring insect problems. Asparagus beetles undergo a physiological process to prepare their bodies to withstand freezing temperatures during winter. Some studies have found low genetic diversity among groups of isolated Chrysomelidae, and use Wolbachia species as a genetic marker. Females lay up to 30 eggs on the end of spear tips as they emerge from the soil. The name is neo-Latin from Greek κριός, ram and κέρας, horn. S & C.

Spear initiation and root growth begin when the soil temperature is above 50°F. Both chew on asparagus spears, which can cause stunting and other cosmetic damage that make the asparagus unmarketable (and consumers don’t enjoy picking up a spear with a bunch of eggs glued to it or a smear of frass (bug poop) on it, either). Crioceris duodecimpunctata or the spotted asparagus beetle is a species of shining leaf beetle belonging to the family Chrysomelidae, subfamily Criocerinae . The twelve spotted asparagus beetle is more common in Wisconsin than the common asparagus beetle.
