A Detailed Explanation of the Occurrence Patterns and Control Methods of the Jujube Leafroller
The jujube leafroller, also known as the jujube sickle-winged tortrix moth, commonly called the leaf-sticking worm, is one of the important pests of jujube trees. The larvae spin silk to roll leaves for feeding, rolling leaves longitudinally into a dumpling shape, or using silk to bind several leaves together. The larvae also bore into and feed on fruit attached to leaves, greatly affecting yield. 1. Occurrence patterns This pest has 3 generations per year, overwintering as pupae in rough bark crevices on branches and trunks. Adults hide by day and emerge at night, are strongly phototactic, and lay eggs 1 to 2 days after emergence; eggs are mostly scattered on smooth small branches and jujube spurs. The egg stage lasts 10 to 25 days, and the first-generation larvae occur

How to control the Euonymus leafroller moth at the right time?
The Euonymus leafroller moth, also known as the Euonymus moth, is one of the earlier leaf-eating pests to harm garden plants. After several years of observation, the author found that in the Xi'an area its larvae appear in late March, mainly harming plants such as Euonymus japonicus (evergreen euonymus), Euonymus bungeanus (winterberry euonymus), and Euonymus fortunei (climbing euonymus). In severe cases they eat all the leaves, affecting the ornamental effect. When low-instar larvae are found causing damage, spray evenly with 50% phoxim emulsifiable concentrate or 40% omethoate emulsifiable concentrate at 1000 times dilution, or with 2.5 deltamethrin emulsifiable concentrate at 2000 times dilution; the control effect is very good.

What are the control methods for the rice leaf roller?
Rice leaf rolling is caused by the rice skipper and the rice leaf roller. For controlling the rice leaf roller, 34% profenofos-fluorine emulsifiable concentrate is a new-generation insecticide. This product is a new compound ultra-long-acting insecticide with a broad insecticidal spectrum and stable efficacy. Field trials show that spraying 50 ml per mu diluted in 40 kg of water, with a treatment interval of 23 days, achieves a control effect of over 95%, requires 2 fewer applications than conventional pesticides, reduces pesticide cost by more than 50%, and can save 2/3 of labor, truly delivering labor savings, cost reductions, and improved quality and efficiency.
