What pesticide is most effective for killing stink bugs? Treatment methods after being bitten
The stink bug, also known as the stink bug (true bug), is a common insect in gardens and landscapes. Every year from May to August it lays eggs in large numbers, damaging crops. So what pesticide is most effective for killing stink bugs? What should you do if bitten?
1. Introduction to the stink bug:
1. What is the stink bug afraid of?
The stink bug is afraid of many animals such as weaver ants, Anastatus wasps, mantises, and spiders, and it particularly dislikes the smell of oleander and the smell of concentrated laundry detergent solution. So friends who want to keep stink bugs away from their homes can plant an oleander in front of or behind the house, or spray concentrated laundry detergent solution on their doors and windows to prevent stink bugs from entering the house.
2. Is the stink bug a beneficial insect or a pest?
Most stink bugs are pests. In the cotton region of the Yellow River basin, 3-5 generations occur each year, overwintering as eggs in dead branches and stubble of alfalfa, broad bean, pomegranate, and apple, as well as in dead cotton branches and boll shells. They hatch in early to mid-April and emerge as adults in late April. Mid-June to mid-July is the peak damage period. Adults are phototactic, lay more eggs in densely growing cotton fields, and prefer high temperatures and rainy conditions. A temperature of 25°C-30°C and a relative humidity above 80% are suitable for egg hatching and reproduction, and damage is most severe in cotton fields near alfalfa fields, green manure fields, or fields with many weeds.
2. What pesticide is most effective for killing stink bugs?
If the insect population is too large and cannot be controlled entirely by manual methods, you can spray a 1000-fold dilution of 80% dichlorvos emulsion or an 800-1000-fold dilution of 90% trichlorfon crystals. If some pine-alkali mixture is added to the trichlorfon solution, the control effect can be improved, and control during the first and second instar nymph stages gives even better results.
In addition, various natural enemies such as weaver ants, parasitic wasps, mantises, and spiders can also be used for control, and they can also be caught and killed in the morning or evening when they are inactive and the dew has not yet dried. Eggs are mostly laid on the leaf surface in egg masses and are very easy to spot, so during the adult egg-laying period from May to August, inspect the orange orchard thoroughly and remove egg masses promptly. However, if a black ring is found under the egg cap, it means the egg has been parasitized by a parasitic wasp and should be left in the field and protected so it can reproduce naturally and increase the number of parasitic wasps in the orange orchard.
3. What should you do if bitten by a stink bug?
If after being bitten by a stink bug there is local redness, swelling, and itching, it is recommended to wash the bitten area promptly, then disinfect it with iodophor, and then apply Likang liquid for disinfection. In addition, regarding diet, it is recommended to avoid spicy and irritating foods and to refrain from scratching.
