Abstract:

Stygofauna sampling predominantly comprises active sampling methods, such as net hauling or hand netting, which although highly effective at collecting specimens, can cause significant specimen damage and is unlikely to collect vagrant species. Studies assessing the efficacy of using stygofauna traps (both baited and unbaited) have been conducted with varying levels of success. Thus, the development of a robust and effective stygofauna trap design may be advantageous. Between 2021 and 2022, in conjunction with Rio Tinto, Biologic began developing and trialling a stygofauna trap designed to sam

Abstract:

Survey and detection of the spotted lanternfly, Lycorma delicatula (White), rely either on traps that exploit the insect’s behavior as it navigates its environment, or on visual surveys of either its mobile life stages or egg masses. A recently described egg mass trap, coined the “lampshade” trap, can assist with early detection in newly infested areas, provide egg masses for researchers, and potentially facilitate spotted lanternfly population reduction by removal of egg masses from the environment. Here, we describe a modified lampshade trap, the sconce trap, that uses less material, can be

AbstractIn biological monitoring, deploying an effective standardised quantitative sampling method, optimised by trap design and sampling effort, is an essential consideration.

Abstract:

A new emergence trap was fabricated for collecting saproxylic insects from precise areas of dead and fallen trees. The trap works on the principle of all emergence traps, i.e., organisms emerging from a substrate get attracted towards light, where they encounter a transparent surface and get collected in a collecting tube with preservative fluid. It is one of the most objective methods for sampling saproxylic insects as they emerge from wood substrata. Using many replicates of this trap, the entire heterogeneity of a substratum like dead wood can be easily covered. The trap can provide a highe

Abstract:

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

There was a significant relationship between the number of viable pupae per trap and the number of healthy western hemlock looper eggs subsequently laid on lichen in the trees.

AbstractThe lesser date moth (LDM) Batrachedra amydraula is a significant pest of date palm fruits. Previously, detection and monitoring of the pest was inaccurate due to high costs of sampling with lifting machines. We report a practical system for detection and monitoring of LDM based on pheromone traps and relevant models. Dose–response experiments with LDM pheromone traps indicated a 1 mg lure is optimal for monitoring. Delta traps with adhesive covering their entire inner surface gave the highest captures while trap colour was unimportant. Sampling pheromone traps throughout the night ind

Abstract:

Ants constitute an important part of arboreal arthropod biomass in rainforests. Nevertheless, there are only a few methods which permit a rapid assessment of these insects in the canopy layer. This study aims at evaluating the efficiency of a new variant type of pitfall trap i.e. “the funnel trap”, to sample arboreal ants in a secondary and gallery forest in Lamto reserve (Côte d’Ivoire). This method was compared to standard arboreal pitfall trap and beating. In total, the 3 methods yielded 7072 ant workers belonging to 43 species, 14 genera and 5 subfamilies.

Abstract:

Traps for capturing mosquitoes and other blood-feeding arthropods are often baited with carbon dioxide (CO2) as an attractant. Dry ice is popularly used as a CO2 source due to its high efficiency and ease of use. However, dry ice can be difficult to obtain in many rural and remote areas. The objective of this study was to develop a simple and inexpensive method that could continuously generate CO2 overnight (about 10 h) while being used with CDC light traps for sampling adult mosquitoes. In principle, CO2 was produced from the reaction between hydrochloric acid (HCl) (12% w/w) and limestone po

However, the consistency of detected responses using different sampling methods, and thus the generality of findings, has seldom been assessed in tropical ecosystems. Hence, we studied the response consistency and indicator functioning of beetle assemblages in altitudinal gradients from two mountains in Malaysia, using Malaise, light, and pitfall traps.

In general, 1.4 ± 0.5 times higher pollen amounts were measured by the trap located at ground level, but this effect was less than expected considering the height difference between the traps.

The genus Corethrella Coquillet, 1902 are known as a group of nocturnal frog-biting-midges (Diptera: Corethrellidae) which locate their frog-hosts through the sound emitted by their conspicuous calls. The classical method to capture these midges consists in using modified Center Disease Control (CDC) traps in which speakers emitting frog calls replace the light bulb. However, the high cost, volume and weight of CDC traps hampers several studies in remote areas and in countries with low research investments. Therefore, the main objective of this study was to compare the capture rate of the clas

Sub-periodic W. bancrofti is transmitted by various Aedes mosquito species, with Aedes polynesiensis and Aedes samoanus being the primary vectors in Samoa. The Aedes scutellaris and Aedes kochi groups are also important vectors in the South Pacific Islands. Anopheles species are important vectors of filariasis in

Background Surveillance of malaria vectors is crucial for assessing the transmission risk and impact of control measures. Human landing catches (HLC) directly estimate the biting rates but raise ethical concerns due to the exposure of volunteers to mosquito-borne pathogens. A common alternative is the CDC-light trap, which is effective for catching host-seeking mosquitoes indoors but not outdoors. New, exposure-free methods are needed for sampling mosquitoes indoors and outdoors in ways that reflect their natural risk profiles.

Sampling fish by trapping can lead to biased conclusions about a population. We used catch data to assess differences between two types of traps for adult sea lamprey (Petromyzon marinus), submerged-funnel traps and studded-tile traps, which are angled ramps with trickle flow leading out of the water. The studded-tile trap at one river caught about 50% more females than the funnel trap. It caught males that had a smaller body size and females with a lower gonado-somatic index (GSI). The likelihood of catching lamprey in the studded-tile trap increased after they had been caught once. This was
