Mechanism of action of "Zhukoed, SK"
In terms of action, “Beetle Eater” is an insecticide, in terms of penetration method it is a contact-intestinal pesticide, and in terms of the nature of action it is a systemic pesticide.
Neonicotinoids have high biological activity, are well accumulated by receptors found in insects, block the transmission of nerve impulses, as a result of which they die from nervous overexcitation. Pyrethroids penetrate the integument of insects, causing rapid destruction, and affect the nervous system of insects, causing paralysis and death.
a) Alpha-cypermethrin provides a contact effect, acts instantly (pests stop feeding within 1 hour after treatment and die)
b) Imidacloprid provides a systemic effect, is quickly absorbed by the leaves and redistributed throughout the vascular system throughout the plant. In addition, imidacloprid provides anti-stress resistance (drought and other unfavorable conditions)
c) Clothianidin provides distribution and long-lasting protection.
The duration of the protective effect is 15–20 days.
The speed of the initial impact is that the pest’s feeding activity ceases within an hour after treatment, and death occurs within 24 hours.
General features of the pest
The Colorado potato beetle, or as it is also called the potato leaf beetle, consumes the leaves of plants such as potatoes, tomatoes, and sweet peppers as food. On average, the length of an adult is from 8 to 12 millimeters, they are characterized by an orange body color with black spots or stripes. Insects have wings, which give them the opportunity to spread over long distances from the breeding site.
The length of the larvae is within 1516 millimeters - they have a black head, black dots on the side of a bright yellow body. They are often confused with ladybugs, which benefit vegetation. Wintering is carried out underground at a depth of 20 to 50 centimeters. In the spring, they begin laying eggs of a light orange hue along the perimeter of the surface of the leaves. They can lay from 5 to 80 eggs per day, and over the entire summer - about 700. The larva is born after 517 days.
It is worth noting that their life expectancy can reach three years - this is possible due to the ability to hibernate for many years, which makes the process of fighting such insects several times more difficult.
The beetle beetle is a complex drug that affects flying and crawling pests, including not only adult representatives of the colony, but also larvae. To get rid of Colorado potato beetles, one treatment of the plantings at the beginning of the growing season is sufficient. The composition of the product includes components that make it possible to restore plants, as well as form root crops.

Biological insecticides to combat the Colorado potato beetle
Insecticides of biological origin are harmless to humans and do not accumulate in different parts of the plant. After the Colorado potato beetle larva eats a leaf treated with the product, it will experience digestive upset. Having lost her appetite, she will soon die, but the fruits and vegetables will remain clean and can be eaten after 5-7 days (if the treatment took place before harvesting).
Biological insecticides do not affect egg laying, so treatment should be carried out weekly and at least 3 times per season.
Rain and watering reduce the effectiveness of the drugs, so treat plants on a clear and dry day
For ease of study, we have placed some drugs in this group in the table.
| Drug name | Release form | Impact on the Colorado potato beetle | Effects on beneficial insects, fish and birds | Duration of protection |
| Akarin | Emulsion concentrate | Kills pests on the 2-3rd day | Highly toxic to bees, slightly toxic to fish and birds | Up to 6 weeks |
| Bitoxibacillin | Powder | Weakens the beetle's appetite, which leads to its death; reduces the number of viable eggs | Slightly toxic to bees and fish, toxic to silkworms | Few hours |
| Fitoverm | Liquid | Kills the beetle within 2-3 days; maximum effect – on 5-7 days | Moderately hazardous to bees and fish | 7-20 days |
| Anthonem-F | Emulsion | Contains cultures of nematodes that parasitize beetles and their larvae, thereby causing disease and killing the host | Low risk | 2 years or more |
Potato varieties resistant to the Colorado potato beetle - myth or reality? Is there a variety of potato in nature whose bushes the Colorado potato beetle “bypasses”? It turns out there is! We found several such varieties and are ready to talk about them.
Restrictions and security
a) Hazard class for bees – class 1 (highly toxic). The use of an insecticide requires compliance with the basic provisions of the “Instructions for the prevention of bee poisoning by pesticides, Moscow, State Aviation Administration of the USSR, 1989.” Notifications about upcoming treatments and
b) Hazard class for humans and warm-blooded animals - class 3 (moderately dangerous compound). When working with the drug, you should follow the measures according to SanPiN 1.2.2584-10. When carrying out treatments, use personal protective equipment, isolate children and pets, and other measures. Store the drug separately from medications and food products, out of the reach of children. The release time after treatment is 3 days.
c) Hazard class for persistence in soil – class 2. If the drug spills, sprinkle the contaminated area with sand or other non-flammable material until completely absorbed. Collect contaminated sorbents in containers for subsequent neutralization. The area of the spill indoors should be washed with water and soap or soda (200 grams of soda per 10 liters of water), and the area of the earth should be dug up.
