Herbicides applied alone have failed to reduce weed populations in agricultural ecosystems. The use of this management strategy has followed other problems such as damage to ecosystems and organisms that live in it. Herbicide resistance in weeds has also occurred more quickly based on the application of herbicides. Today, most scientists are looking for new integrated weed management programs in agricultural ecosystems. Biological control is one of the most effective ways of weed management. In this way, living organisms are used to reduce and control weed species in arable lands. Weed seed predators, including predispersal and postdispersal predators as biological control agents, can be primary factors of weed seed mortality in agricultural ecosystems. This review has discussed factors influencing seed predator populations, activity, and granivory. Knowledge of the interrelations between factors and seed predators can contribute to designing future strategies that augment weed seed predator activity and enhance weed seed consumption as a component of an integrated weed management system.

“…A reduced dosage of field applications of insecticides and herbicides can help to maintain carabid activity (Navntoft et al 2006). Some insecticides such as synthetic pyrethroids, which are considered less toxic to nontarget organisms, have been reported to cause sublethal toxicity among carabid species (Tooming et al 2014).…”

“…Moreover, permethrin was more toxic if it was applied topically, compared to the situation where larvae were exposed to pyrethroid film on filter paper. The extent of the Fastac 50 EC (active ingredient: alpha-cypermethrin) insecticide knockdown effect on the predatory carabid beetle showed positive concentration dependence, being most effective at the highest alpha-cypermethrin concentration (Tooming et al 2014).…”

“…No comparative study is available about the most decisive factors, which determine the hyperactivity length of the insects. Concentration proved to be a significant feature when carabids, Platynus assimilis (Tooming et al 2014(Tooming et al , 2017 and Scarites quadriceps (Prasifka et al 2008) were tested. Frequency shows the number of times each class-interval occurs.…”

Behavioural traits, including locomotor activity, have become relevant parameters in contemporary ecotoxicology. However, insecticide effects on soil animal behaviour has remained a neglected field until now. The Trebon 30 EC is an expansively used pyrethroid insecticide in many countries, which has a broad spectrum of activity. It is recommended against pests of different vegetables, cereals, fruits, and flowers. The effect of this insecticide on the behaviour of collembola Folsomia candida has never been tested. Nevertheless, an effect is likely, because of the neurotoxic nature of the Trebon 30 EC insecticide. This study aimed to determine, (i) whether the Trebon 30 EC insecticide (active ingredient: etofenprox) prevails on the collembola F. candida locomotor activity pattern immediately after insecticide application and (ii) if there is any temporal change in the locomotor activity pattern within one hour of insecticide application. Prompt hyperactivity followed by strongly reduced locomotor activity of F. candida due to Trebon 30 EC application has been demonstrated in this study. Collembola started to run faster even when a tenfold concentration of the recommended field rate was applied. Moreover, this insecticide causes locomotor irregularity in F. candida. Chronic insecticide exposure has a negative impact on all studied locomotor traits of this collembola, resulting in a knockdown effect.

“…EthoVision (Noldus et al, 2001) is a sophisticated software package with an activity detection feature (Noldus Information Technology, 2015a), which has been used to assess the locomotor effects of insecticide on carabid beetles (Tooming, Merivee, Must, Sibul, & Williams, 2014), and the effect of anti-viral drugs on the locomotor activity of ferrets (Oh, Barr, & Hurt, 2015). Though successful, the EthoVision software is expensive, and its source code is not available for inspection and modification.…”

SwarmSight: Measuring the temporal progression of animal group activity levels from natural-scene and laboratory videos

et al. 2016

View full text Add to dashboard Cite

We describe SwarmSight (available at: https://github.com/justasb/SwarmSight), a novel, open-source, Microsoft Windows software tool for quantitative assessment of the temporal progression of animal group activity levels from recorded videos. The tool utilizes a background subtraction machine vision algorithm and provides an activity metric that can be used to quantitatively assess and compare animal group behavior. Here we demonstrate the tool utility by analyzing defensive bee behavior as modulated by alarm pheromones, wild bird feeding onset and interruption, and cockroach nest finding activity. While more sophisticated, commercial software packages are available, SwarmSight provides a low-cost, open-source, and easy-to-use alternative that is suitable for a wide range of users, including minimally trained research technicians and behavioral science undergraduate students in classroom laboratory settings.
