Abstract:

Wind soil erosion is one of the most important causes of soil degradation that impede the process of sustainable agricultural development. The first step to mitigating wind erosion hazards is to find an effective and accurate way to assess its severity. Therefore, the main objective of this research was to raise and evaluate the efficiency of the new four traps to measure eroded soil, Fixed Distance trap (FD), Fixed Point trap (FP), Rotary Distance trap (RD) and Rotary Point trap (RP). The study traps RP and FP compared with the Big Spring Number Eight trap (BSNE) (traditional trap) and the tr

Abstract:

Abstract Traps constructed by an animal reduce the amount of energy required to seek prey. The main risk of trap-building predators is the greater uncertainty of encountering prey, owing to their immobility. Sometimes environmental characteristics do not allow them to build efficient traps, resulting in lower capture success. We observed prey escape, capture success, and behavior of two antlion species, Cueta lineosa, a habitat specialist, and Myrmeleon hyalinus, a generalist, building geometrically different traps. The traps of C. lineosa are elaborate and deep, consisting of two inverted con

A crucial aspect of conservation management for endangered newt species is the establishment of a monitoring methodology and the evaluation of trap efficacy to ensure the accuracy of data collection. In this study, we assessed three funnel trap types (prism shape, umbrella shape, and Ortmann's trap) to capture great crested newts (Triturus cristatus). We also tested three baits (chicken liver, chemical lights in glow sticks, and control traps without bait) and determined the optimal trap control time within a 12 h period.

The current study focuses on different types of beetle’s traps in rubber plantations in the localities of Bongo and Toupah, in the south of Côte d’Ivoire. The objective of this work is to determine the most efficient trap for capturing beetles in these agrosystems. Four trapping methods, namely yellow trap on the ground, yellow trap at height, screen trap and pitfall trap were used in plantations of different ages. The investigation resulted in more captures of beetles from the screen traps with means of 236.5 and 365.5 beetles in Toupah and Bongo, respectively. Pitfall traps captured fewer in

Without using the fans and baited with pheromone only, these new trap designs capture beetles three to five times as efficient

Abstract Native bees provide important economic and ecological functions that include pollination of agricultural crops and natural plant communities, thus conservation of their declining populations is important. The use of pan traps for collecting and monitoring bee populations has become widespread because the method samples widely different habitats with equal effort. However, to the best of our knowledge no efforts have attempted to quantify their efficiency. We measured the efficiency of pan traps at collecting bees by using video cameras to record individuals coming to the traps. Videoe

Baited pitfall traps represent a widely utilized method for dung beetle sampling. The effectiveness of this approach can be influenced by various factors, such as the type of bait used, trap size, and modifications to trap components. An important challenge during trapping is the inadvertent capture of non-target animals (such as: frogs, lizards, snakes, small rodents, and spiders), a concern that becomes more pronounced if endangered species are involved. To address these issues, incorporating a mesh panel into pitfall traps can help prevent unwanted intrusions. In this study, we assess the e

Larvae of the antlion Callistoleon manselli New build pitfall traps that have attached radiating furrows. In order to evaluate this unique trap-building behaviour from an evolutionary viewpoint, we analysed the shape of,traps in the field, then examined the process of trap construction and the efficiency of the pitfalls in prey capture. Larvae of C manselli construct the radiating furrows after building the central pit. Larvae provided with food ad libitum tend not to construct furrows at all. Capture efficiency for the pits with furrows was greater than for pits without furrows. The pitfall t

Abstract Assessments of novel capture techniques are important to wildlife research. We used Comstock traps, a new live-capture technique, to capture North American river otters Lontra canadensis. We measured Comstock trap functionality in terms of river otter capture efficiency, furbearer capture efficiency, nonfurbearer capture efficiency, and malfunction rate. During 2014–2016, we captured 36 river otters (19 male, 17 female) in Comstock traps during 2,533 trap nights (1 capture/63 trap nights) at Crab Orchard National Wildlife Refuge in southern Illinois, USA.

Abstract:

Arbovirus diseases, such as dengue, chikungunya, and Zika, are important public health problems. Controlling the major vector, Aedes aegypti, is the only approach to suppressing these diseases. The surveillance of this mosquito species needs effective collecting methods. In this study, a simple MosHouse sticky trap was evaluated in a semi-field condition. Our results demonstrated the efficiency of this trap in collecting Ae. aegypti males, and no significant difference (p > 0.05) in the numbers of males was detected when compared with the widely used BG- Sentinel trap.

Tsetse flies are the vector of protozoan parasite of the genus Trypanosoma, the causative agent of human African sleeping sickness and animal trypanosomiasis.

However, there is no evidence regarding their comparative efficiency in catching flies using olfactory cues. Therefore, the present study aimed to evaluate the efficiency of different types of traps in catching tsetse flies at Nech Sar and Maze National Parks, Southwestern Ethiopia.

The wing trap, although economical and commercially available, has never been seriously considered as a standard for monitoring populations of the corn earworm (CEW)/cotton bollworm, Heliothis zea (Boddie), mainly because it is considered inefficient relative to other available traps. Attempts were made to enhance the performance of the Pherocon 1C (P-1C) wing trap by modifying its structure and by varying the placement of the pheromone within the trap. P-1C traps receiving 40–50 g of supplemental adhesive captured 5.1-fold more CEW males than did the P-1C standard. The introduction of horizon

Improving the efficiency of these traps would improve the ability to respond to green crab invasions.
