CATDOLL : CATDOLL:What color are Varroa mites?

1. What color is the Varroa mite?

1. Morphological characteristics: Bee mites are dioecious organisms. Female mites are oval in shape, with a brown body color. The body is covered with a keratinized dorsal plate with a reticular pattern. The ventral surface is composed of a thoracic plate, a genital plate, an inguinal plate, a ventral plate, and anal plate. Male mites are oval in shape, with a light yellow body color, and have less bone than female mites.

2. Reproduction process: Bee mites are dioecious organisms. Female mites mate with male mites in the sealed larval chamber of bees. Eggs are laid on the wall or bottom of the cell. Most of them lay 2 to 5 eggs. After the eggs hatch, they parasitize on the surface of the bee pupa to absorb hemolymph. When the female mite lays only one egg, it usually develops into a female mite. When it lays multiple eggs, one egg must develop into a male mite.

3. Development cycle: Bee mites go through three stages in their life cycle: egg, nymph (including early nymph and late nymph), and adult mite. The egg stage of the giant bee mite is 20 to 24 hours, the early nymph is 52 to 58 hours, and the late nymph is 80 to 86 hours. The egg stage of the small bee mite is 15 to 30 minutes, the early nymph is 44 to 48 hours, and the late nymph is 48 to 52 hours.

To sum up, bee mites are the main external parasites of Italian honey bees. They reproduce in honey comb cells throughout their lives, lay eggs in uncovered larval cells, develop in covered larval cells, parasitize on the surface of larvae, pupae and adult bees, and feed on the hemolymph of bees (pupae and adult bees). In mild cases, it affects the normal development of the bee colony, and in severe cases, the colony will be rapidly weakened.

2. What are bee mites?

Phylum Arthropoda, Subphylum Chelicerata, Class Arachnida, Order Acari, Family Laeleridae. This is an external parasitic mite of honey bees, which reproduces in the honeycomb cells throughout their lives. It lays eggs in the uncovered larval cells, reproduces in the covered larval cells, parasitizes larvae, pupae and adult bees, and sucks hemolymph, which shortens the life span of bees, reduces their collecting ability, and affects the production of bee products. In severely affected bee colonies, a large number of larvae and pupae die. The newly emerged young bees are incomplete, crawling around everywhere, and the strength of the bee colony is rapidly weakened.

3. What kind of mirror can be used to see bee mites?

Mites can be seen on bees using a magnifying glass.

Bee mites are a kind of pests. They are very small and difficult for ordinary people to see. Only experienced beekeepers can identify them based on the appearance of the bees. This disease is also called "rot disease". Treatment method: remove the bees from the hive, burn a paper roll containing stinking realgar into smoke, fumigate the beehive for 15-30 minutes, and then put the bees back when the time is right to remove the mites.

4. What are the habits and characteristics of the bee mite larvae in Insect Book?

Characteristics: Bee mites are dioecious organisms. The female adult mites are oval in shape, brown in color, and covered with a completely keratinized dorsal plate with a reticular pattern. The ventral surface is composed of a sternum, genital plate, inguinal plate, ventral plate, and anal plate. The male adult mites are oval in shape, light yellow in color, and have relatively little bone.

5. What is the difference between large Varroa mites and small Varroa mites?

Varroa mites and Varroa mites are both external parasites of honey bees.

1. The main difference is that the parasitic points are different

Varroa mites parasitize the larval chambers of honey bees, the capped pupal chambers, and the bodies of honey bees;

The Varroa mite is a typical parasite in the nest cell, mainly parasitizing on bee larvae and pupae.

2. Symptoms are different

The symptoms of bee colonies damaged by large and small bee flies are basically similar. Bee flies suck the body fluids of bee larvae and pupae, causing bees to be stunted, have mutilated limbs, and shorten their lifespans. Young bees that leave the nest have no wings or have curled wings, crawl out of the nest door, and crawl on the ground in front of the nest door.

If you see a lot of young bees with broken wings when inspecting the bee farm, it means that the bee mite parasite is very serious and you should take measures immediately. When checking for large bee mites, use tweezers to open the capped nest cells, especially the drone cells, and you will find large bee moths parasitizing. In serious cases, large bee moths may also parasitize the bees. When checking for small bee mites, you can also open the capped nest cells and face the sun. The small bee moths will crawl out of the nest cells, so you can determine whether the bee colony is harmed by small bee moths.
