Abstract:
The phytophagous insects of vegetable and melon crops in Central Fergana consists of 148
species and 7 subspecies belonging to 113 genera and 32 families of 7 orders. 19 species (12.3%)
are found in Central Fergana for the first time. Among these species, the representative of
Pentatomidae family Eurydema oleracea (Linnaeus, 1758) and the Aphididae family Aphis
frangulae beccabungae Koch, 1855, was not registered previously in fauna of Uzbekistan. In
addition, today, Uzbekistan is experiencing adventive and quarantine species of Phthorimaea
operculella (Zeller, 1873) (potato beetle), Tuta absoluta (Meyrick, 1917) (Tomato leaf miner)
and Myiopardalis pardalina Bigot, 1891 (melon flies) was registered for the first time in Central
Fergana. Among the vegetable species, the number of polyphage per vegetable and melon is 69,
of which 19 species (12.3%) are fully replicable insects in agrocenosis. Only typical for
vegetable crops are 78 (50.3%), which are not found in fields. As well as, only 6 varieties of field
pests in food range (3.9%) do not contain vegetables. Dominant species amount to 45 (29%) in
various agrocenosis of Central Fergana. The dominant genius in the fauna are 22 (19.5%), with
40 species (25.9%) insects in many agrocenosis. The analysis shows that Central Fergana's
vegetable and melon rops are different from the general fauna of Uzbekistan. The analysis shows
