Comprehensive Control Methods for the Peach Borer Moth in Peach Cultivation
The peach borer moth larvae bore into and feed on peach fruit, causing gumming; the fruit discolors and drops, or the interior becomes filled with insect frass, making it unfit to eat, and this has a great impact on both yield and quality. I. Occurrence pattern. In Shandong, this pest occurs in 2-3 generations per year, mainly overwintering as mature larvae in cocoons inside damaged mummified peaches, bark crevices, gaps among loose stones in embankments, chestnut burs, sunflower heads, castor seeds, and corn and sorghum stalks, with a small portion overwintering as pupae. In Shandong, the first moth emergence of the overwintering generation occurs in mid-May, with the peak in early to mid-June; most eggs of the 1st generation are laid on early-maturing peach varieties, with the most eggs laid on the ventral (belly) side; the newly hatched larvae appear in mid-to-late June and mainly damage early-maturing peach fruit, boring into the fruit to feed; mature larvae spin cocoons and pupate at the stem cavity of damaged fruit and in bark crevices. The 1st-generation adults begin emerging in early July, with the peak from late July to early August; adults are highly selective in egg-laying, basically laying eggs on late-maturing peach varieties and pomegranates; newly hatched 2nd-generation larvae are found in mid-to-late July, with the peak in early to mid-August; by late July, larvae are already found maturing and pupating. The pupation peak is in mid-to-late August. As late-maturing peaches begin to be harvested, adults then move to other crops to lay eggs and continue causing damage.

Identification and Control Methods for the Carambola Fruit Borer Moth
The carambola fruit borer moth is commonly known as the red-line worm. Its larvae occur in large numbers during the flowering period and invade the small flowers to feed on the stamens. The peak occurrence period is usually from late June to early August, and the damage is most severe in extremely hot weather. All the damaged small flowers drop off, often causing crop failure. During the summer full-bloom period, trichlorfon 1000x solution can be sprayed continuously every 5 to 7 days to kill the pests.

Control Methods and Medication Tips for Powdery Mildew, Brown Spot and Stem Borer Moth on Dahlia pinnata
Pest and disease control methods for Dahlia pinnata: powdery mildew breaks out heavily from September to October, control it with antifungalmycin 120; brown spot occurs from June to August, spray Bordeaux mixture or chlorothalonil; for viral diseases, prevent aphids and leafhoppers from transmitting the virus; for stem borer moth larvae, spray fenitrothion, so that Dahlia pinnata blooms more brilliantly.
