Assessment of patch quality by ladybirds: role of larval tracks

Oecologia, 1998
Gravid females of the two-spot ladybird, Adalia bipunctata (L.), were deterred from ovipositing when kept in petri dishes that had previously contained conspecific larvae but not conspecific adults, or the larvae of another two species of ladybird, Adalia decempunctata (L.) and Coccinella septempunctata L. The deterrent effect was density dependent and

Behavioral Response to Larval Tracks and the Influence of Tracks on Intraguild Scavenging by Coccinellid Larvae

Journal of Insect Behavior, 2009
A paired design was used to determine that Harmonia axyridis 4th instars were not influenced by the presence of conspecific larval tracks, but well-fed H. axyridis 4th instars spent less time on plants that contained tracks left by Coleomegilla maculata 4th instars.

Response of Coccinellid Larvae to Conspecific and Heterospecific Larval Tracks: A Mechanism That Reduces Cannibalism and Intraguild Predation

Environmental Entomology, 2011
Cannibalism, where one species feeds on individuals of its own species, and intraguild predation (IGP), where a predator feeds on other predatory species, can both pose significant threats to natural enemies and interfere with their biological control of pests.

Assessment of patch quality by ladybirds: relative response to conspecific and heterospecific larval tracks a consequence of habitat similarity?

Chemoecology, 2006
Aphid colonies can reach high levels of abundance but last for short periods of time. The larvae of aphidophagous ladybirds (Coleoptera: Coccinellidae) that feed on these colonies might therefore suffer from starvation, which favours the occurrence of cannibalism and intraguild predation. Thus, the assessment of patch quality becomes crucial and it has

Live tracking of extracellular vesicles in larval zebrafish

2020
Formerly considered as insignificant cell debris, extracellular vesicles (EVs) have emerged as potent mediators of cell-cell communication, both in proximity and at distance from the producing cell. EVs are transported in body fluids and can be internalized by specific distant cells to ultimately deliver a functional message.

Prey Tracking by Larval Zebrafish: Axial Kinematics and Visual Control

Brain, Behavior and Evolution, 2005
High-speed imaging was used to record the prey-tracking behavior of larval zebrafish as they fed upon paramecium. Prey tracking is comprised of a variable set of discrete locomotor movements that together align the larva with the paramecium and bring it into close proximity, usually within one body length.

Model sensitivity and robustness in the estimation of larval transport: A study of particle tracking parameters

Journal of Marine Systems, 2013
Abstract Many marine organisms spend their early lives as planktonic larvae dispersed by ocean currents. Predictions of larval transport are important for a wide range of applications including the interpretation of population genetics, fisheries management, and the planning of no-take marine protected areas.
