Abstract:

Delingha is located in the east of the Qaidam Basin, which is a place with little precipitation, plenty sunshine, dry climate, high altitude and large temperature difference. These features provided appropriate prerequisites for developing of green agriculture. By 2021, Delingha has a total crop planting area of 279,000 mu, with major crops including licium, wheat, leafy vegetables, legumes, and potatoes, etc.. The climate of this place is particularly suitable for the growth licium. In Delingha, pest control still depends onmainly chemical control greatly. Limited biological control with natural enemies has been carried out. The predacious natural enemies play important roles in producing green agricultural products and protecting ecological balance. From 2018 to 2021, we surveyed species and population dynamics of predacious natural enemies in licium plantations. At the same time, a malaise trap was used to collect insect information complementarily. Therefore, a dataset of predacious natural enemies in the special habitat in Delingha was developed. This dataset includes species, numbers, and picture information of the collected local arthropod predators in Coccinellidae, Syrphidae, Neuroptera and Araneae. Environmental and meteorological information of the survey sites are also included. This dataset provides basis for appropriate application of natural enemies and chemical control in the future.
