Armyworms have to be without 30 days

From north to south in China, 2 8 generations can occur in a year. Adults have migratory characteristics Migrate from the south of the Yangtze River to the north to the Huanghuai region to breed in the month Infest wheat crops in the month Pupae and become pests and then move to the northeast, northwest and southwest to breed in the month Infest wheat, corn, rice and pasture in the month, pupate and feather adults migrate south to Shandong, Hebei, Henan, northern Jiangsu and northern Anhui to breed, causing damage to corn and rice. The larvae and pupae can overwinter smoothly or continue to be harmful south of 33°N latitude (0 isotherm in l), but cannot overwinter in areas north of this line.

Adults have strong tropism to sweet and sour liquid and black light, and larvae are nocturnal and infestive, and have the habit of feigning death and group migration. Armyworms prefer humidity and are afraid of high temperature and drought, with a relative humidity of more than 75% and a temperature of 23-30 degrees that is conducive to the laying of eggs and the survival of larvae. However, excessive rainfall, especially after storms, has led to a significant drop in armyworm populations.

At the maize seedling stage, the eggs are mostly laid at the tip of the leaves, and at the adult stage, the eggs are mostly produced in the bracts of the ears or the filaments of the ears. While giving birth, it secretes gum, and the egg grains are adhered to the leaves in rows or overlapping arrangements to form egg masses.

So it depends on the environment you're in, as described above.

As the weather changes, it can only become less and less--- and it will not be in winter.

First, these insects are generally diurnal and nocturnal. Insects with such habits like shade rather than light.

Second, look at whether there are gaps in your doors, walls, beds, etc., which are usually waiting for natural light to darken in.

There used to be armyworms in my house, especially in the early hours of the morning, they were afraid of light, and as for where they went, they hid in a particularly cold and damp place, like a corner, which was difficult for us to find.

As the name suggests, the armyworm is the kind of bug that sticky crawls with water traces, and generally hides in a damp and cold corner during the day, after all, this kind of bug should not be exposed to the sun.

Hide in the dark and spray the spray.

There are many types of natural enemies of armyworms, such as birds, frogs, bats, spiders, nematodes, worms, predatory insects, parasitic insects, parasitic fungi and microorganisms. Among them, the beetle can prey on a large number of armyworm larvae; The parasitism rate of armyworm parasitic flies on the first generation of armyworms was high; Sparrows and bats can prey on a large number of armyworm adults; Ladybugs, aphid-eating flies, and lacewings can prey on young larvae. Protecting the living environment of natural enemies and increasing the number of natural enemies can effectively control armyworms.

Afraid of salt, as soon as you sprinkle salt, you die.

It is afraid of water, salt, and light.

It's almost impossible to get all the bugs dead. It's good to be able to die more than 95%.

If the weather is good, it will take a few hours.

The good weather is pretty much it for today.

If the pesticide used is appropriate and the dosage is in place, it will be effective after two hours.

Clean the corners frequently to prevent the accumulation of garbage, and disinfect them frequently.

That's about 10 to 20 days, and it depends on the temperature, the humidity, and the food.

There is an interest-free period for credit card consumption, but the interest-free period for credit cards varies from bank to bank.

Hello, if you hold a China Merchants Bank credit card for consumption, the bank will not charge you a handling fee, and the general merchant will not charge you a handling fee.

The interest-free period refers to the period between the date of bank billing and the due date of repayment for the consumption transactions that are eligible for interest-free treatment when the credit card holder repays the full amount due before the due date (inclusive). The interest-free repayment period shall be 50 days at most, unless otherwise agreed between the card issuer and the applicant unit, provided that the maximum interest-free repayment period shall not exceed the maximum interest-free repayment period required by relevant laws and regulations (except for cash advances).

After the credit card is issued, there is a specified bill date and repayment date, you can call the credit card to manually confirm the statement date and repayment date of your credit card.

There is also a cycle of credit card repayment, and the "statement date" refers to the date on which the card issuer summarizes the cardholder's accumulated outstanding consumption transaction principal, cash withdrawal transaction principal, fees, etc., settles interest, and calculates the repayment amount due by the cardholder every month. "Payment Due Date" means the last date by which the Cardholder should repay the full amount due or the minimum payment as specified by the Issuer (the amount of the purchase amount can be repaid by the due date and at the latest by 24 o'clock on the date of payment). For example:

If the 5th of each month is the bill date and the 23rd of each month is the repayment date, the consumption from the 5th of the previous month to the 4th of the current month will be repaid on the 23rd of the current month.

There is no interest on repaying before the repayment date.
