AB  - Tokom 2017.godine na području Beograda u štitovima male smrčine štitaste vaši, Physokermes hemicryphus
(Hemiptera: Coccidae), koja se razvija na biljkama iz rodova Picea i Abies, prvi put je registrovano istovremeno
prisustvo larve predatora Anthribus nebulosus (Coleoptera: Anthribidae) i larvi parazitoida Pseudorhopus testaceus
(Hymenoptera: Encyrtidae).
A. nebulosus je predator većeg broja vrsta iz familije Coccidae i smatra se najefikasnijom vrstom entomofaga u
smanjenju brojnosti populacija Ph. hemicryphus. Celokupno razviće predatora odvija se ispod štita vaši, gde se larve
hrane jajima vaši. P. testaceus je poliembrionijski parazitoid čiji je ciklus razvića sinhronizovan sa Ph. hemicryphus.
Ženke parazitoida polažu jaja u larve prvog stupnja domaćina, ne ometajući njihov dalji rast i metamorfozu, pa imaga
osica eklodiraju iz ženki štitastih vaši.
Obe vrste entomofaga su u stranoj i domaćoj literature registrovane kao značajni prirodni neprijatelji male smrčine
štitaste vaši, pri čemu je ovom prilikom utvrñeno da se larva A. nebulosus, osim jajima štitastih vaši, hrani i larvama i
lutkama poliembrionijskog parazitoida P. testaceus. Imajući u vidu različit način ishrane larvi, cilj istraživanja bio je da
se utvrdi uticaj hrane na variranje morfoloških karakteristika i mase tela imaga A. nebulosus.
U cilju gajenja A. nebulosus štitovi vaši sa jajima i štitovi vaši sa larvama i lutkama parazitoidne osice, u kojima se
razvijala larva predatora, su odvojeni u pojedinačne staklene flakone, nakon čega je praćena eklozija imaga. Analiza
morfoloških karaktera (dužina pokrioca, širina pokrioca, dužina buta) kao i merenja mase tela obavljena su na po 16
jedinki predatora pomoću softverskog paketa IM1000 (Leica, Germany) u laboratoriji Katedre za entomologiju i
poljoprivrednu zoologiju Poljoprivrednog fakulteta u Beogradu.
Utvrñeno je da način ishrane larvi A. nebulosus utiče na morfološke karakteristike imaga i da postoje statistički
značajne razlike izmeñu svih ispitivanih karaktera. Tako su dužina pokrioca (2355,02±58,69 vm), širina pokrioca
(1917,02±36,61 vm), dužina buta (824,27±29,44 vm) i masa tela(0,0052±0,0003 g), jedinki koje su se hranile
larvama i lutkama P. testaceus bili statistički značajno veći od dužine pokrioca (2001,95±58,73 vm), širine pokrioca
(1645,53±50,33 vm), dužine buta (719,29±20,00 vm) i mase tela (0,0032±0,0003 g), jedinki koje su se hranile
jajima Ph. hemicryphus.

AB  - Scale insects from the family Coccidae are considered as very important pests in agriculture, forestry and horticulture, so they require regular monitoring and application of control measures, which are still largely based on the use of synthetic insecticides. However, one of the potentially use- 
ful ways to control these insects is to use natural enemies, among which predators play an important 
role, which has initiated the study of their diversity and the role in regulating scales insects number.
During 2015-2018 year, predatory larvae were collected from field together with infested plant material, and then reared in the laboratory until the imago eclosion, individually in petri dishes or jars, in order to prevent the cannibalism. After the edosion, the imagoes have been prepared and determined. The species determination was carried out based on appropriate keys or with the assis¬tance of experts - taxonomists,
During the research, 16 species of scale insects from Coccidae family, 17 species of predators from 7 families and 5 insects orders were collected and reared.
The largest number of species (10) belongs to the order of Coleoptera: Anthribus fasciattis For¬ster and Anthribus nebulosus Forster (Anthribidae), Chilocorus bipustulatus (L.), Chili:wows renipustu¬lotus (Scriba), Coccinefia septempunctata L,, Exochomus quadripustulatus 1, Harmonia axyridis Ilippodamia variegata (Goeze), Propylea quatuerciecimpunctata (L.) and Scymnus abietis Paykull (Coccinel I idae).
Three species are from the Hemiptera order: Oxycarenus lavaterae (Fabricius) (Lygaeidae), Atrac¬rotomus mail (Meyer-Dur) and Deraeocoris ruber (L.) (Miridae).
From the order of Dermaptera, two species were reared, Anehnura bipunctata (Fabricius) and I orticula auricularia L. (Forficulidae),
One species was reared from the order of Diptera, Leucopornyia siiesiaca (Egger) (Chamaemyii¬dae), and one from order Neuroptera, Chrysoperla cameo (Stephens) (Chrysopidae).
Seven species of predators were found on scale insects from the Coccidae family for the first time in Serbia: Harmonic axyridis, Hippodamia varieguta, Propylea quatuordecimpunctata, Anechura lifpunctata, Forncula auricularia, Oxycarenus Iavaterae and Deraeocoris rube!. The spedes Anechura litpunctata and Oxycarenus /avaterae were determined for the first time as Coccidae predators, not only in Serbia, but also in the world.
The most effective predator of soft scale insects in Serbia is A. nebuiosus, reared from the colo-nies of Euieranium tiliae (L.), Parthenoiecanium comi (13DucMi), Parthenolecanium rufulurn (Cockerell), Physokerrnes hemicryphus (Dalman) and Physokermes piceae (Schrank). The highest efficacy was ibserved at Ph. piceae (53.24-58.03%), and the lowest at P. rufulum (10.65.12,78%).

AB  - European fruit lecaniurn, Parthenoleconium corni (Bouche, 1844) (Hem iptera: Coccidae) is a cm mopolitan, polyphagous species, It represents significant pests of woody plants, especially Worm and fruit trees from the Prunus genus. Occasionally it appears on the plums in numerous colonial when it causes significant damage.
In our country, the mass propagation of this species was registered in the 1930s and 195(1.. when more than 16 million and 4.5 million plum trees were cut down. Due to great damage,13k)Ifill ical protection measures were studied during this period and it was determined that many natural enemies play a significant role in reducing the populations of this pest. Since then, there has been no more detailed research of distribution and natural enemies of this species at the Serbia territory
The research was carried out in the period from 2015 to 2017 at 27 locations in Serbia. SampliLii plant material with scale insect colonies was brought to the laboratory, where it was examined kir scale insects presence and then deposited in glass cylinders for the cultivation of natural enemies.
Scale insects were registered in all examined locations in Serbia, on 30 species of plants from I 0 botanical families, including different types of fruit trees, forest and decorative plants.
During our research, on the P. corni we found 19 types of natural enemies, including 12 spetli.s of parasitoids and 7 species of predators.
Of the parastoids (Hymenoptera: Chalcidoidea), three species of the Aphelinidae family were reared: Cocrophagus lycininia (Walker), Coccophagus scuteliaris (Dalman), Coccophagus shiliongentit (Hayat and Singh) and nine species from the Encyrtidae family: Anagyrus schoenherri (Westwood), Blastothrix Iongipennis Howard, Cheiloneurus daviger Thomson, Metaphycus dispar (Mercet), Mr t aphycus insidiosus (Mercet), Metaphyrus maculipennis (Timberlake), Metaphycus melanostomatut (Timberlake), Metaphycus punctipes (Dalman) and Metaphycus zebratus (Mercet), The species shi/longensis, was determined for the first time in Serbia. These species of parasitoids reduced tlw number of scale insects populations by 8-56%.
Following predators, were reared: Anthribus nebuiosus Forster, Anthribus fasciatus Fur t.it (Coleoptera: Anthribidae), Chilocorus bipustulatus (L), Chilocorus renipuswiatus (Scriba). Excidlonni% quadripustulatus L, Harrnonia axyridis Pallas (Coleoptera: Coccinelliclae) and Chtysoperia carnea phens) (Neuroptera: Chrysopidae). The most effective predatory species is A. nebulosus which hos reduced the number of scale insects population by 21-24%,
