Мақолада Наманган вилоятининг Чуст ва Поп туманларидаги олмазор боғларда олиб борилган тадқиқот натижаларига асосланиб, олма қизил қон шираси (Eriosoma lanigerium)нинг ҳудудга хос бўлган биологияси ва экологик хусусиятлари ҳақида маълумотлар келтирилган. Мазкур туманлар экотопик шарт-шароитлари ўзига хослиги ҳамда ифлосланиш даражасининг олма қизил қон шираси (Eriosoma lanigerium) ривожланишига таъсири ўрганилган.

В статье, на основе исследований, проведенных в яблочных садах Чусткого и Папского районов Наманганской области, представлены сведения о биологии и экологических свойствах кровяных тлей (Eriosoma lanigerium), характерных для данной территории. Исследованы влияние своеобразных экотопических условий и степени загрязнённости данного региона на развитие кровяной тли (Eriosoma lanigerium).
V.V.Yahontov’s work titled “Central Asian agricultural pests” suggests that an apple of red blood aphid is native to North America and this insect entered Europe with tree seedlings 200 years ago. This pest was brought to Uzbekistan in 1905 as a result of seedlings.
There are winged and wingless varieties of this pest. There is white feather on the surface of abdomen of winged aphid. The body of this aphid formed as cylindrical and its length is about 22 m.m. The rest of his body: head, chest and legs are seen black and the abdomen is dark brown.
The color of winged apple of red blood aphid differs from wingless aphid. The color of this aphid was found in the same dark red color in the village of Kayirma, Chust district of Namangan region and Uygur village of Pop district as well. It is possible to see that this wingless aphid’s body is covered with feather white dust like wax. This plant louse is called strange feather aphid as well.
If we pay close attention to the biology of this aphid, we can see unusual peculiarities that is this type of aphids can be found in different ages of tiny sizes and in an adult stages during winter periods. In both areas where research was conducted – apple of red blood aphid was found in the roots of apple trees, within its bark and nut’s branch fissures.
According to V.V.Yahontov’s information, this aphid winters as an egg stage in the fields of elms in Northern America which is the homeland for that aphid.
It is required +5 C temperature for hatching or period of being larva and wintering or awaking from winter sleep of apple of red blood aphid. The second area where we investigated aphid was Chust district of Namangan region – we observed that; awaking period of this aphid was in 2018, March 23; at the same time this aphid wasn’t found in the neighbouring district Pop. Initial aphid larras were defined in this area when it came on April 12.
We conducted our research on 18 apple sorts which we selected from both regions. It was defined that – the temperature in the village of Kayirma, Chust district differed for 1-2 degrees than that of Uygur in Pop district.
During our research we examined the size of their primitive colonies; they were 20 cm2 in the village of Kayirma on April 22 and as for the village of Uygur they formed 18 cm2 colony in 18 plantations totally.
As with other types of aphids, the increasing dynamics of this kind population occurs twice a year. Accordingly, the dynamics of initial population was analyzed; this phenomenon occurred on June 16 and they covered 1.44 cm2 area in 18 apple plantations. The same index was almost seen ation index on June 20 when Pop district was examined. At the same time, occupying of 15 apple seedlings by them was 1.58 cm2 square.
Hot temperatures, dry air in summer and the increase in the number of useful insects prevent the reproduction of Eriosoma langerium aphid and there is a sudden drop in the amount of aphids.
