In this paper, we present the results of field investigations on the suitability of three types of trunk traps (‘Commercial 1’, ‘Commercial 2’, and ‘Prototype’) for capturing spongy moth (Lymantria dispar) larvae in two areas with different climates and forest ecosystems. In areas of NE Slovenia, which were characterized by Pannonian climate and re...

Diatomaceous earth (DE) consists of fossilized remnants of diatoms, which are marine or freshwater unicellular algae. Most DEs originate from fossilized sedimentary layers of diatoms deposited in water bodies during the Eocene and Miocene periods, much more than 20 million years ago. Processed DE, a soft, chalky powder, is widely used as an insecti...

With over 1000 species of pests causing losses in both the quantity and quality of stored food, insect contamination poses significant challenges. The present study assesses the efficacy of the combination of λ-cyhalothrin and chlorantraniliprole against four key storage pests—Trogoderma granarium, Sitophilus oryzae, Rhyzopertha dominica, and Tribo...

It is about 40 years since Prostephanus truncatus, a devastating pest of stored maize and dried cassava, was accidentally introduced into Africa from meso-America. Losses of stored maize at least doubled because of the destructive nature of the pest. Prostephanus truncatus management measures generated and recommended then worked at that time. Howe...

Tetranychus urticae (Acari: Tetranychidae) is a pervasive and damaging mite pest of tomato crops, leading to important economic losses globally.

Rhynchophorus ferrugineus (Olivier) (Coleoptera: Curculionidae), the red palm weevil (RPW), is a concealed voracious pest of different ornamental and economically important palm species, particularly the date palm. It can cause huge losses in ornamental and commercial palm plantations. RPW has spread rapidly from its original distribution in Southe...

The spongy moth, Lymantria dispar L. (Lepidoptera: Eribidae), is a serious pest of deciduous forests and causes widespread defoliation. Despite this, few studies have evaluated the wide-ranging surveillance of adult male L. dispar using different types of pheromone-baited traps. We evaluated the effect of trap type on captures of adult male L. disp...

The European spongy moth, Lymantria dispar dispar (L.) (Lepidoptera: Erebidae), originating from Eurasia, is found in Europe, Africa, and North America. Its polyphagous larvae infest deciduous and coniferous trees, causing severe damage during mass outbreak years. Thus, it is listed as one of the top 100 invasive alien species worldwide. The manage...

Simple Summary This study investigated the behavioral asymmetries and mating success of Alphitobius diaperinus (Panzer) (Coleoptera: Tenebrionidae) under sublethal exposures to α-cypermethrin. Control males exhibited a right-side bias, which increased the likelihood of successful copulation, especially when head butts preceded mounting. A similar p...

Tetranychus urticae (Acari: Tetranychidae) is a widespread and serious mite pest that infests tomato plants and causes economic losses worldwide.

The resistance of insect populations to the existing insecticides grows fast due to their continuous use. Thus, the need for new and effective formulations is increasing. Isolated compounds of botanical origin may represent a promising solution for green pest management strategies. In this study, isofuranodiene derived from Smyrnium olusatrum L. (A...

The botanical substances constitute valuable alternatives to synthetic insecticides. In the last decades, numerous substances of natural origin have been tested against stored-product insects, mostly as fumigants or for contact toxicity, while there is limited knowledge on the efficacy of plant secondary metabolites if used as grain protectants. In...

Apiaceae is a family encompassing medicinal and aromatic plants. They produce essential oils (EOs) inside oil canals, known as ducts and vittae, which occur in their vegetative and reproductive organs.
