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  - During a study on soft scales (Hemiptera:
Coccomorpha: Coccidae) and their natural enemies in
Serbia, the parasitoid Coccophagus shillongensis Hayat
and Singh 1989 (Hymenoptera: Chalcidoidea:
Aphelinidae), a new species for Serbia, was recorded.
Originates from India, from where it was incidentally
introduced to Europe and first recorded for in Greece in
2017. Since then, there are no other data on this parasitoid.
During our research in 2016–2018, the species was
registered in the area of Belgrade at eight localities. It
was eclosed from six species of soft scales, five ofwhich
were new hosts. In addition to adult females, it also
parasitizes instar nymphs, which was not known until
now. The finding of males of this species in Serbia
represents the first record outside India.

AB  - Parthenolecanium persicae (Fabricius) (Hemiptera: Coccidae) is a paleartic species found on over 70 host plants, with the highest damage being recorded on grapevine and plums. In Serbia, this one is more abundant on extensive orchards or physiologically weakened plants. Bionomy of P. persicae was studied from 2015 to 2019 in three localities: Aleksandrovac, Belgrade and Neštin. Sampling of plant material was performed throughout the year, in interval of 7 to 10 days during vegetation, or, once in month during plant dormancy. From each infested plant, five one- or two- years old twigs 20 cm long were taken. Sampled plant material with scale insect colonies was brought to the laboratory, where it was examined for scale insects presence and then deposited in glass cylinders for the rearing of scales insects and natural enemies. The determination of the eclosed parasitoids was performed by eng. Aleksandar Stojanović. P. persicae developed one generation per year and overwintered as second instar larva on grapevine shoot and trunk. Females emerged during April and early May, and oviposition was recorded in mid-May. Each female layed on average 2001 ± 3,4 white eggs. First instar larvae appeared during June. In the summer, they feed mainly on young shoots, leaves and leaf petioles. In late August and early September, second instar larvae were formed, which continue to feed until October when they migrated to shoots or hidden places on the trunks where they overwintered. Numerous colonies of P. persicae was recorded in the Belgrade locality, which resulting in discoloration, drying and premature leaf fall. In the vineyards of Aleksandrovac and Neštin, scale insects was present on individual plants, with no visible symptoms of damage. During our research, on the P. persicae we found 7 species of natural enemies. Of the parasitoids (Hymenoptera: Chalcidoidea), 6 species were eclosed: Coccophagus lycimnia (Walker), Eunotus obscurus Masi, Marietta picta (Andre) (Aphelinidae), Metaphycus dispar (Mercet), Metaphycus insidiosus (Mercet), Metaphycus maculipennis (Timberlake), (Encyrtidae), and from predators, the species Exochomus quadripustulatus L. (Coleoptera: Coccinellidae).
