These beetles should not be confused with the 'green mint beetle' (or Chrysolina herbacea), as it is greener in appearance (emerald green, [4]) and slightly larger in size, [2] as C. herbacea measures 7–11 mm in length. [7] C. herbacea and Chrysolina graminis (tansy beetle) both have a mixture of fine and coarse punctures on the pronotal disk ...
The small hive beetle was first discovered in the United States in 1996 and has now spread to 27 U.S. states, including Hawaii. An infestation by small hive beetle was triggered in 2015 in British Columbia which led to a temporary quarantine. [11] In Mexico, the small hive beetle has become established in at least eight states.
The beetles' legs and pronotum are the same as their basic colour, [3] and they have antennae. [5] Chrysolina herbacea is large and has a long, oval shape. [6] The adult beetles can be 8–10 mm long and have black-coloured larvae, [4] [7] which also feed on mint leaves. [2] The adults have complete wings, but they only seldom fly. [6]
The lifecycle of this beetle includes pupation in the ground outside of the hive. Controls to prevent ants from climbing into the hive are believed to also be effective against the hive beetle. Several beekeepers are experimenting with the use of diatomaceous earth around the hive as a way to disrupt the beetle's lifecycle. The diatoms abrade ...
Scarabiasis, or "beetle-disease", is a condition where beetles temporarily infest the digestive tract of other animals. It can also affect humans, and despite being a rare phenomenon, [1] it is the second most important insectal disease in humans after myiasis, which is caused by the larva of flies. The term is commonly used as a synonym of ...
Beekeepers may harvest honey from July until October, according to the honey flows in their area. Good management requires keeping the hive free of pests and disease, and ensuring that the bee colony has room in the hive to expand. Chemical treatments, if used for parasite control, must be done in the off-season to avoid any honey contamination.
Adult Pyrophorus beetles feed on pollen and sometimes small insects, such as aphids or scale insects. Their larvae feed on various plant materials and invertebrates, including the larvae of other beetles. Eggs are luminous and are deposited either on or in the soil. [citation needed] Mature larvae and pupae are also luminous. They grow slowly ...
The alarm pheromone has shown to be attractive to the small hive beetle. Therefore, there is a tradeoff between recruiting guards bees to defend the invaders and attract more beetles. The small hive beetle has a lower sensing threshold for the honeybee pheromone, which exacerbates the damage to honeybee hive. [39]
