Camouflage in predators [PDF]

open access: yesBiological Reviews, 2020
ABSTRACTCamouflage – adaptations that prevent detection and/or recognition – is a key example of evolution by natural selection, making it a primary focus in evolutionary ecology and animal behaviour. Most work has focused on camouflage as an anti‐predator adaptation. However, predators also display specific colours, patterns and behaviours that reduce

Population dynamics of aphid and coexisting predators in tomato agroecosystem

open access: yesJournal of Agrometeorology, 2021
Aphids generally attack vegetative plant parts, preferably leaves, and devitalize the plant by sucking the cell sap. Thorough knowledge of pest-predator ecology and their interaction is requisite to initiate timely pest management strategies ...

Modelling encounter rates and distribution of mobile predators and prey [PDF]

open access: yes, 2009
Marine ecosystem models often contain modules for two phytoplankton compartments (flagellates and diatoms) and two zooplankton groups (micro- and mesozooplankton).

Estimating the distribution of demand for Antarctic krill (Euphauisa superba) from land-based predators at South Georgia [PDF]

open access: yes, 2007
South Georgia is renowned for the abundance of Antarctic krill (Euphausia superba) and a range of krill predators. Variability in krill availability at a range of scales, and the consequences of this for predator-prey interactions, mean that quantifying ...

Banana flower thrips (Thysanoptera) and their natural enemies in Magdalena, Colombia

open access: yesTemas Agrarios, 2015
Banana crops are one of the most important economic activities in the department of Magdalena with more than 12.000 ha of crops. Due to the quality standards required by international markets, phytosanitary problems need identification ...

THE POTENTIAL OF THREE LARVAL PREDATORS AGAINST FALL ARMYWORM SPODOPTERA FRUGIPERDA (LEPIDPTERA: NOCTUIDAE) UNDER THE LABORATORY CONDITION [PDF]

open access: yesActa Scientifica Malaysia, 2021
Most cereal crops are often damaged by lepidopterous insects. Of recent, fall armyworm, S. frugiperda (J.E. Smith) has resulted into yield and economic loss in many African and Asian countries.

Species Diversity and Community Structure of Arthropod Pests and Predators in Flax, Linum Usitatissimum L. from Darjeeling (India)

open access: yesBrazilian Archives of Biology and Technology, 2018
The species richness and relative abundances of different aboveground plant-dwelling pest and predator species were assessed in flax (Linum usitatissimum L.) ecosystem under mid-hill conditions of eastern Himalayas. The experiment was conducted in winter

Pest species diversity enhances control of spider mites and whiteflies by a generalist phytoseiid predator [PDF]

open access: yes, 2009
To test the hypothesis that pest species diversity enhances biological pest control with generalist predators, we studied the dynamics of three major pest species on greenhouse cucumber: Western flower thrips, Frankliniella occidentalis (Pergande ...

Landscape and farm management influence generalist predators [PDF]

open access: yes, 2002
Chemical pest control is currently the dominant form of pest management against insect pests in agroecosystems, but has negative side effects. Biological control by specialist predators has been successful in greenhouses, but has not been successfully ...
