What are the control measures for the box tree pyralid (Diaphania perspectalis)?
Boxwood is a major evergreen ornamental plant in gardens. In recent years, careless introduction of plants has allowed the box tree pyralid (Diaphania perspectalis) to damage two small-leaved boxwood species, Buxus sinica and Buxus bodinieri, from south to north. From the larvae feeding on the leaf mesophyll to spinning silk to make nests and binding leaves together, it severely affects boxwood growth and can even kill the affected plants entirely. Morphological characteristics and occurrence pattern: The adult has a white-brown body and white, semi-transparent wings; the front edge of the forewings is brown, the medial cell has a fine white spot and a curved crescent-shaped white spot, and the outer margin of the hindwings has a brown band.

Control Methods and Key Technical Points for the Peach Fruit Borer in Plum Trees
Symptoms: The hatched larvae bore into the fruit from the base of the fruit stalk, tunnel along the pit into the fruit to feed, and the gum flowing from the bore hole together with the brown frass excreted by the larvae sticks to the fruit surface, causing the tunnel to overflow with frass and making the fruit unfit to eat. Control method: During the peak egg-laying periods of the first and second generations of adults in April to May, when most of the eggs on the fruit turn red, promptly spray 2.5% deltamethrin at 2500 times dilution, 50% phoxim emulsifiable concentrate at 1000 times dilution, or 40% omethoate at 1000 times dilution.

Detailed Explanation of the Rapid Cultivation Method for Standard (Tree-Form) Honeysuckle
Honeysuckle, as a raw material for pharmaceuticals, beverages, and beauty and cosmetic products, has long been in short supply on both domestic and international markets. Most regions of our country are suitable for its cultivation. At present, ground-covering shrub-type cultivation is mostly adopted in various places. In order to develop toward three-dimensional cultivation, make full use of space, increase light exposure, and improve its yield and quality; and also to provide a new tree species for roadside ornamental greening, the cultivation and development of standard (tree-form) honeysuckle has become an urgent task. For this reason, we carried out a series of studies on the cultivation techniques of standard (tree-form) honeysuckle in Pingyi County, the hometown of honeysuckle. Now

Control Recommendations for the Overwintering Generation of the Box Tree Pyralid Moth
The box tree pyralid moth (Glyphodes perspectalis) is one of the important leaf-eating pests of forestry plants in this district, mainly damaging Chinese box (Buxus sinica var. parvifolia) and Japanese box (Buxus bodinieri). Since early spring this year, the whole district has carried out 2-3 rounds of comprehensive control against this pest, effectively bringing the damage under control; however, since the damage period of this pest is long and can last until the end of October, continued follow-up monitoring of this pest is still needed. According to monitoring at two sites, the Anting Ginkgo Garden and the Fangtai Flowers and Plants Horticultural Farm, a moth peak appeared under the forecasting lamp in early to mid-September, with the highest moth numbers on September 7-9, averaging 22.3 moths per lamp per day
