AB  - Stem weevils (Ceutorhynchus pallidactylus and Ceutorhynchus napi) are significant pests of oilseed rape that farmers regularly suppress by insecticide treatments intended against Brassicogethes aeneus. Recent studies have shown that in some regions of northern Serbia C. napi is dominant, while C. pallidactylus prevails in others. Increased damage from stem weevils has elicited an exploration of the situation and a study of their phenology and effects of insecticides in three differently managed fields: conventional, organic and integrated. New findings regarding the phenology of stem weevils show that both species were sporadically present in our experimental oilseed rape fields as early as during autumn (from the end of October 2010, BBCH 17-18). The main period of stem weevil settlement is the end of winter and early spring. Maximum flight of both weevil species was recorded on March 23 at the beginning of oilseed rape (OSR) stem elongation (BBCH 22-25), and one week later in the organic field. There were no significant differences in the number of settled weevils among the three differently managed fields. The insecticide treatment against C. napi was applied two weeks earlier than the usual treatment against B. aeneus and C. pallidactylus. Thus, it is clear that insecticide treatment directed against B. aeneus and C. pallidactylus is not effective against C. napi. In this way, such a practice can contribute to an increase in OSR damage, and density of the next generation of C. napi. A new generation of C. pallidactylus emerged from OSR fields in June 2011, while the majority of C. napi emerged in March of the following year.
AB  - Ceutorhynchus pallidactylus i Ceutorhynchus napi su značajne štetočine uljane repice koje farmeri redovnu suzbijaju insekticidnim tretmanom protiv Brassicogethes aeneus. Nedavne studije su pokazale da u nekim regionima na severu Srbije dominira C. napi, a u drugim regionima C. pallidactylus. Povećane štete od stablovih rilaša ukazale su na potrebu praćenja njihove fenologije, efekata insekticida i uticaj agrotehnike. Utvrđeno je po prvi put da je pojava ovih insekata (C. napi i C. pallidactylus) na poljima uljane repice već tokom jeseni, od kraja oktobra 2010 (BBCH 17-18). Glavni period kada oni naseljavaju uljanu repicu je tokom kraja zime i na početku proleća. Maksimalni let je zabeležen 23. marta, u vreme izduživanja stabla uljane repice (BBCH 22-25). U odnosu na primenjenu agrotehniku nije bilo značajnih razlika u broju insekata koji su doletali. Registrovan broj doletelih imaga C. napi bio je 2,7 puta veći nego C. pallidactylus. U skladu sa tim, insekticidni tretman je bio 25. marta 2011. Posledica dominacije C. napi je potreba za primenom insekticida oko 2 nedelje ranije u odnosu na termin kada se suzbijaju B. aeneus i C. pallidactilus. Stoga je jasno da konvencionalna jednokratna primena insekticida za suzbijanje B. aeneus nije efikasna protiv C. napi i da takva praksa doprinosi tako velikim razlikama u brojnosti ova dva rilaša. Nova generacija C. pallidactylus izleće već tokom juna meseca iz zemljišta sa uljanom repicom (BCH 76-88) dok glavnina imaga C. napi izleće naredne godine u martu mesecu.

AB  - Polydrusus (Polydrusus) picus ssp. picus (Fabricius, 1792) which belongs to the family of weevils (Coleoptera: Curculionidae) has been recorded in a high number during the spring 2017 in Belgrade area, Serbia. The adults were detected on aronia plants firstly, and than on strawberry plants and Celltis occidentalis L. leaves. The most of them were found feeding on the youngest leaves. On aronia and C. occidentalis plants, adults fed on young leaves along the periphery of the leaf blade and between the veins. On strawberry plants, adults fed on the same way on young leaves, but also damaged the leaf petioles, sepals, floral and fructal peduncles. High number of adults were found on aronia plants, but the most significant damages were detected on strawberry plants.
AB  - Tokom proleća 2017. godine, na više lokacija na području Beograda (Srbija), utvrđeno je prisustvo brojnih imaga rilaša Polydrusus (Polydrusus) picus ssp. picus (Fabricius, 1792). Prva imaga nađena su na sadnicama aronije u prodaji, a potom su u većem broju registrovana na aroniji i jagodi u okućnicama i na američkom kopriviću (Celtis occidentalis L.). Odrasle jedinke su se hranile grizući mlade listove po obodu, ostavljajući karakteristična oštećenja.

AB  - Our research of the genus Ceutorhynchus associated with oilseed rape was conducted in northern parts of Serbia (Stari Žednik, Subotica). A specific assemblage of eight weevil species was found. The most numerous were stem weevils Ceutorhynchus napi with 81% of all trapped specimens, followed by C. pallidactylus with 18%. The remaining six weevil specimens were C. obstrictus, C.erysimi, C. minutus, C. picitarsis, C. sulcicollis and C. typhae, comprising 1% of all trapped insects. Stem weevils C. napi and C. pallidactylus began to immigrate into the oilseed rape fields in autumn, as early as November 10 (BBCH 17-18). The maximum flight was recorded at the beginning of oilseed rape stem elongation (BBCH 22-25) on March 23. A new generation of C. pallidactylus emerged from oilseed rape fields in June (BBCH 76-88), while individual specimens occurred during the autumn. The majority of C. napi emerged in March next year, sporadically until May 7. As a consequence of C. napi dominance insecticide treatment should be performed earlier than usual, i.e. when C. pallidactilus is the primary target.
