Trapping and killing composition for preventing and controlling small beetles in beehives and application method
Technical Field
The invention belongs to the technical field of agricultural pest control, and particularly relates to a trapping and killing composition for controlling beehive beetles and an application method thereof.
Background
The Beehrla nidus Aethina tubida Murray belongs to Coleoptera, Nitidulidae, and is one of six important pathogens of bees. It was originally distributed in the African continent southward in the Sahara desert, and in 1998, Beatles beetles were first discovered in the Florida states of the United states (Hepburn and Radloff,1998) and by 2002 have spread to 25 states, causing serious losses to the beekeeping industry in the United states. In recent years, it has been spread successively to Egypt (2000), Canada (2002), Australian (2002), Italy (2014) and Korea (2016) countries and regions (Neumannet al, 2016; Toufailia et al, 2017; Leeet al, 2017). And it is known that beetles of the honeycomb are found in some parts of China.
The bee hive beetle is a parasitic insect in bee colony, the insect has wide spread route, strong viability and fast reproduction speed, and the adult insect feeds on honey, pollen and even bee larva to cause the death of bee larva and larva, and can still survive for more than 5 days without food (Hufuliang and Zhuwei, 2002). When the larva of the small beetle in the honeycomb digs into a hole and passes through the honeycomb to eat the honey and pollen in the honeycomb, the part where the larva passes is damaged, the whole honeycomb collapses and is accompanied by a fermentation phenomenon, the honey foams and overflows the honeycomb, even flows out of a beehive, and the quality of the bee product is seriously affected (soldiers in the army, 2005). In addition, the beetle larvae of the hive often leave a sticky substance with odor and emit an odor similar to rotten oranges, forcing the bee colony to abandon the hive and escape (Zhao Hongyao et al, 2018). Once a colony is heavily infected, either a strong or weak colony, it is destroyed within two weeks.
The prevention and treatment of the Beatles nidulans, until now, no method for thoroughly radically treating the Beatles nidulans exists. The chemical agent control methods that can be used are: U.S. medicine "checkmate +" for beehives, which checks for beetle larvae in the hive; the drug "Gardsar" used for treating soil is used for interrupting the breeding cycle of the Beatles nidulans and preventing the spread of the Beatles nidulans. However, such trapping compositions and applications are currently lacking.

The second purpose of the invention is to provide a method for trapping and killing the small bee hive beetles, which is characterized in that the trapping and killing composition for preventing and controlling the small bee hive beetles is put into a trapping and killing bottle, and is put near a bee hive to trap and kill the small bee hive beetles with poison, and the trapping and killing bottle is provided with a plurality of holes for the small bee hive beetles to enter on the wall of the bottle.
Preferably, the trapping and killing bottle is a polypropylene plastic empty bottle, and a plurality of holes for the honeycomb beetles to enter are arranged on the trapping and killing bottle.
Preferably, the size of the hole on the trapping bottle is 3.5mm long (long axis) and 2.0mm wide (short axis) (chest width of worker bee in bee >3.5mm), so that the bee is prevented from entering the trapping bottle through the trapping hole while the bee larva can smoothly enter the trapping bottle, and the bee is prevented from being injured.
According to the invention, the strong tropism of the small honeycomb beetles to the trapping and killing composition is utilized to prepare the trapping and killing agent, so that a large number of small honeycomb beetles are trapped and gathered in the trapping and killing bottle in which the trapping and killing composition is laid, and the small honeycomb beetles die due to contact of pesticides on the body surface.
The invention has the advantages that: the trapping and killing composition for preventing and controlling the beetles in the beehive utilizes the slow-release substance with special smell to prepare the trapping and killing agent, attracts a large amount of the small beetles in the honeycomb into the trapping and killing bottle coated with the trapping and killing composition, and utilizes the insecticide to kill the small beetles in the honeycomb, so that the bee honeycomb is protected from being damaged by the small beetles in the honeycomb. The trapping and killing composition has the characteristics of low cost, high efficiency, environmental friendliness and the like. The trapping and killing composition for the small bee hives and the application thereof have wide industrialization prospect, the preparation method is simple, and the composition is particularly suitable for preventing and controlling the small bee hives in bee hives and has wide economic and social benefits.
