This article reports the first finding of the Southern Swallowtail, Papilio alexanor Esper, 1800 (Lepidoptera: Papilionidae) in Serbia. The butterfly fauna of Serbia now comprises 202 species. A single male specimen was collected on May 9th, 2025, on a warm, dry serpentinite slope in southwestern Serbia, in the Zlatibor Nature Park, Čajetina munici...

The evaluation of diatomaceous earths (DEs) against a wide range of major stored-product insect pests highlights their possible importance in integrated pest management protocols, as an environmentally friendly alternative to conventional insecticides. This study was conducted to evaluate the insecticidal efficacy of two DEs from Serbia (DE S-1 and...

The seed beetle (Acanthoscelides obtectus) is a pest of common beans and other legumes that causes considerable losses of stored products. Its populations are universally regulated with insecticides, but novel, safer and more efficient methods of control are needed. One such method is the Trojan Female Technique (TFT) which is based on the existenc...

The insect silk protects the larvae that produce it. This implies that it may contain biologically active substances that can be used in medicine. In this paper, the cytotoxic and proapoptotic potential of Indian meal moth (Plodia interpunctella) silk extract was examined after 72 h of exposure to the SW-480 human colorectal adenocarcinoma cell lin...

Application of alternative methods of protection, as well as Rhyzopertha dominica infestation affects the rheological quality of wheat and triticale. Two varieties of wheat Planeta and Kruna and two varieties of triticale KG-Bingo and KG-20 were tested. To test the effects of diatomaceous earth, two diatomaceous earth dusts (DE) marked as S-1 and S...

Diatomaceous earth products (DEs) are a promising alternative to conventional, synthetic insecticides for controlling many different insect pests (Korunić, 1998; Kavallieratos et al., 2005), among which is the P. interpunctella (Kljajić et al., 2009). We conducted a laboratory testing of the insecticidal efficacy of two Serbian diatomaceous earth p...

This work aimed to assess the potential of thermal treatments for controlling P. interpunctella on sunflower seeds, based on its tolerance to high/elevated temperatures and effect on seed vitality. The tests involved mature larvae (L5) and pupae, exposed to 35, 40, 42, 44, 45, 50, 55 and 60 °C, for 15 and 30 min, and 1, 2, 6, 24, 48 h. Larval morta...

This paper reports the first findings of the allochthonous weevil species Alcidodes karelinii (Boheman, 1844) in Serbia. It is distributed throughout the Eurasian steppe belt, and recently it has been spreading westwardly. The specimens from Serbia were found thanks to citizen science in two localities in Vojvodina Province (North Serbia): Ada Muni...

Different agro-ecological conditions have a great influence on the phenotypical expression of yield components and grain yield. Besides this, their relationships are changed, too. In extreme wet conditions of the year, with large amounts of precipitations during the most important development stages, phenotypic differences and the relationship betw...

Poljoprivredni gubici uzrokovani različitim bolestima i aktivnošću štetočina u razvijenim zemljama dostižu 30–40%, a u zemljama u razvoju čak 60–80%. Sintetički insekticidi su decenijama dominantan vid suzbijanja insekata u poljoprivrednoj proizvodnji i zaštiti prehrambenih proizvoda. Međutim, njihova učestala i prekomerna korišćenja imaju negativn...

Tip ishrane, a pre svega sadržaj i količina nutrijenata u hrani značajno utiču na morfološke karakteristike herbivorih insekata. Bakrenasti plamenac, Plodia interpunctella (Hübner, 1813), izrazito je polifaga i ekonomski veoma značajna vrsta plamenaca, koja nanosi ogromne štete uskladištenim prehrambenim proizvodima. U ovom istraživanju praćen je u...

This study aimed to evaluate insecticidal activity of Spinosad applied at doses of 0.25, 0.5, and 1.0 mg kg-1 (ppm) on Rhyzopertha dominica in wheat, barley, rye, oats and triticale grains. Mortality was assessed after 7 and 14 days, while impact on progeny production was assessed after 8 weeks. In the lowest dosage after 7 days of exposure, Spinos...

Many mushrooms, such as Cantharellus and Lepista spp., are almost resistant to insect attacks. However, only a few studies about the possibilities of using mushrooms in the protection of stored cereals from storage insect pests have been performed. Lactifluus piperatus is a non-toxic, edible mushroom, but rarely consumable due to its very strong, s...

Legumes represent a valuable source of proteins in human and animal nutrition, as well as of different nutrients. Also, they enable diversification of agroecosystems and can be considered climate smart crops. Therefore, they are gaining importance in both developed and developing countries. The most important, and often limiting factor in legume pr...

The aim of this study was to assess the susceptibility of nine dried fruit species (apple chips, prunes, sour cherries, raspberries, blackberries, strawberries, chokeberries, goji berries and figs) to be infested by Plodia interpunctella in laboratory conditions. Six dried fruit species (prune, sour cherry, raspberry, blackberry, strawberry, and ch...

Higher plants represent a rich source of bioactive compounds and can be used to develop environmentally safe means for insect control. Ajuga species are well known by their antimicrobial activity, while only a few reports indicate repellent and insecticidal activity towards stored product pests. This work aimed to assess the potential of A. pyramid...

One of the most promising biorational pest management practices for seed protection is the application of high temperatures (heat treatments). It is a hundred-year-old technology, effective for disinfesting stored commodities from insects, primarily in bins and grain-processing facilities. The aim of this work was to determine the heat tolerance of...

During project activities conducted in the territory of the Landscape of Outstanding Features “Dolina Pčinje” in 2021, T. balkanicus was registered for the first time in Serbia.

The Balkan Peninsula has a Eurasian position and represents the link and intersection of roads between Europe and Asia, since ancient times. As well, it is recognized as European biodiversity hotspot. Invasive alien species present one of the major treats to biodiversity, closely related to massive species extinctions in last century. To prevent IA...

Laboratory bioassays (temperature 26 ± 1 C and 60 ± 5% r. h.) were performed to evaluate the insecticidal effect of three different diatomaceous earths (DE) against Rhyzopertha dominica (F.) in wheat, triticale and rye. In order to achieve this, the amount of damaged kernels, amount of debris, wet gluten content, gluten index and rheological proper...

Rice weevil, Sitophilus oryzae is one of the most devastating primary pests of stored grains. Adults feed mainly on endosperm, while larvae feed on germ, resulting in reduced germination and nutritional value of kernels. The influence of a commodity condition on the food preferences of S. oryzae has been well documented, but the influence of previo...
