Description

Technical Field

[0001] The utility model belongs to the technical field of biological control, and particularly relates to a stacking device for mass-rearing mealybugs. Background Art

[0002] Mealybugs, belonging to the Psoralea family of the order Hemiptera, are a significant pest that damages a wide range of important agricultural and forestry crops. They primarily harm tropical and subtropical plants, including pineapples, bananas, and sisal. Their eggs, larvae, and adults can parasitize the surface of host plants, affecting their growth through sucking. They feed on leaves, twigs, buds, and fruit, and can reproduce rapidly, leading to malnutrition, yellowing leaves, wilting treetops, tree decline, and significant leaf and fruit drop. In severe cases, they can even cause plant death.

[0003] To address the serious damage posed by mealybugs, numerous researchers both domestically and internationally have conducted extensive research and practical control efforts, achieving significant progress. These efforts primarily focus on their bioecological characteristics, population dynamics, monitoring and early warning, chemical control, and pheromone trapping. Research on mealybugs requires large numbers of mealybugs, and artificially rearing mealybugs has become a primary means of providing a standardized and consistent source of experimental insects. This has important implications for other biological research and the rearing of natural enemies such as ladybugs. Currently, the standard indoor breeding method involves rearing mealybugs in open spaces on various host plants. Due to the characteristics of mealybugs, such as their gregarious, cryptic nature, the propensity of young larvae to crawl, the secretion of nectar, and their preference for dark, warm, and humid environments, potted cultivation on most host plants often results in widespread dispersal and escape, resulting in low survival rates and making large-scale rearing and collection difficult. This, in turn, hinders their reproduction and compromises their proper rearing. Therefore, there is a need for a stacked device for mass-rearing mealybugs to carry out breeding operations on mealybugs parasitic on plants, which can provide support for theoretical research and prevention and control practices of mealybugs.
