When is the control time for rice stem borers?
Rice stem borers bore into the rice stems as larvae to feed, posing a huge threat to rice. When is the control time for rice stem borers? 1. Control time for rice stem borers The control time for rice stem borers must be determined according to the pest situation and the seedling condition. Chemical control should be carried out from the peak of egg hatching to before the occurrence of first-instar larvae. The specific time should be based on the information from the local plant protection station.

What are the control methods for rice stem borers?
Netizen Yeshan Judicial Office sent an email on July 4: I am a staff member of the town agricultural technology station. Right now we have too many rice stem borers here, and they are hard to control! I had farmers use Dakuangsha and dimethoate, but the feedback was that the control effect on stem borers was poor. May I ask what methods should be used to control them

What are the control methods for citrus flat-headed borer?
The citrus flat-headed borer (Agrilus auriventris) has one generation per year in the Chenggu area, overwintering as larvae of various instars inside the branches and trunks of citrus trees. In late March, the larvae bore into the xylem and begin to pupate; mid-to-late April is the peak pupation period, with the pupal stage lasting about 25 days. Early May is the peak emergence period for adults, and mid-May

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.
