Bioecology, Harm And Efficiency Of Certain Preparations Against The Apple Fruit Sawer (Hoplocampa Testudinea Klug.)

Аннотация

This article provides data on the harmfulness, distribution and lifestyle of the apple sawdust widely noted in recent years in the intensive orchards of the republic. In order to determine the effectiveness of insecticides against olm arrakashi, observations were first carried out based on the sex pheromone. On this basis, in three variants, the drugs Dalate Plus 10% ae, Entovant 15% ae, Protect 5% em.k were tested, a higher efficiency was observed in the variant where the drug Dalate Plus 10% ae was used, - 0,2 l / ha, where the biological efficiency was 86.7% in comparison with the control. KEYWORDS Bioecology, harm, control, efficiency of certain preparations, harmfulness, distribution, lifestyle. INTRODUCTION from pests and diseases. More than 100 pests and diseases known to damage orchards are One of the main factors in increasing the productivity of orchards is their protection The US A Journals Volume 03 Issue 05-2021 36 The American Journal of Agriculture and Boimedical Engineering IMPACT FACTOR (ISSN – 2689-1018) 2021: 5. 554 Published: May 31, 2021| Pages: 36-38 Doi: https://doi.org/10.37547/tajabe/Volume03Issue05-07 OCLC - 1121105746 known. In the process of global climate The adult larva eats all the seeds and change, the prevalence of pests and diseases completely destroys the seed chamber. varies as a result of inconsistent weather each Depending on the size of the fruit, each larva year. With a good knowledge of the can damage 3 to 6 fruits. Fruits that are not bioecological characteristics of pests, it is very damaged by the seed chambers usually do not important to carry out control measures in fall. In June, the larvae complete their their most vulnerable period. development, leaving the fruit, fall to the ground and form cocoons in dense soil. In the Hoplocampa testudinea Klug. The length of absence of moisture, they go into a state of the adult insect is 6-7 mm, the upper part of diapause and remain in the soil for up to two the body is brown, the lower part is yellow. It years. The damage done to the apple fruit by has two pairs of transparent wings with a the arrakash is similar to the damage caused network of black double veins. The larva has a by the apple moth. white, brown head and 10 pairs of legs. The length of the adult larva reaches 12 mm. The The difference is that the moth eats some of dome is thick oval, densely cocoon-shaped. the seeds, while the arrakash completely The larvae overwinter at a depth of 5-10 sm in destroys all the seeds. Holes in fruits damaged the soil, sometimes they can be found at a by moths are usually covered with debris. The depth of 20 sm.In spring, the larvae grow holes made by the apple larvae remain open when the soil at a depth of 10 sm heats up to and a rusty red liquid comes out of them. Pest 10°C. Adult insects occur and appear on the larvae emit an unpleasant odor reminiscent of buds of apple trees before flowering. the smell of rust. Apple fruit sawer (Hoplocampa testudinea Klug.). In order to test and determine the biological effectiveness of some pesticides, observations and experiments were conducted in a 3-hectare orchard in Kibray district, Tashkent region.
