1. Route reassessment by transporter ants improves speed and directional accuracy of cooperative transport in Formica japonica

Author:
Hisamoto, Shumpei; Hosaka, Natsumi; Matsunami, Yuka; Iwasaki, Hideo

Subject:
insect behavior,   etc   ; Formica; worker ants;     Show all 3 Subjects
Abstract:
... Encircling cooperative transport in ants is categorized into coordinated and uncoordinated types. Coordinated cooperative transport is considered to be advantageous for ants because it transports food quickly without creating a deadlock. Contrarily, uncoordinated transport is slow and frequently becomes deadlocked. This study assessed the characteristics of uncoordinated cooperative transport, whi ...

Abstract:
... Continuous jumping behavior, a kind of endurance locomotion, plays important roles in insect ecological adaption and survival. However, the methods used for the efficient evaluation of insect jumping behavior remain largely lacking. Here, we developed a locomotion detection system named JumpDetector with automatic trajectory tracking and data analysis to evaluate the jumping of insects. This autom ...

Abstract:
... Microbial symbiosis is widespread among insects. This article reviews our understanding of insect behaviors relevant to commensalistic and mutualistic microbial symbiosis, which has received relatively less attention compared to insect behaviors in parasitic symbiosis. First, we review our knowledge of symbiont transmission behaviors by which the host insects maintain associations with beneficial ...

insect behavior,   etc   ; Drosophila; descriptive studies; grooming (animal behavior); legs;     Show all 5 Subjects
Abstract:
... Insect grooming prevents disease and preserves sensory functioning. Grooming movements have not been examined in flies, so this descriptive study was undertaken, using frame by frame analysis of videographs. Drosophila was chosen because of recent interest in neural systems that control grooming. Head grooming occurs in discrete bouts during which the well-bristled forelegs serve as brushes that s ...

Abstract:
... In 1948, British geneticist A. J. Bateman published in the journal Heredity the results of his experiments on the fruit fly Drosophila melanogaster. Bateman hoped he was bringing evidence for the ‘greater dependence of males for their fertility on frequency of insemination’ (Bateman, 1948, Heredity, 2(3), p. 364), thus purportedly explaining ‘an undiscriminating eagerness in the males and a discri ...

Abstract:
... Research on the connections between gut microbes and the neurophysiology and behavior of their animal hosts has grown exponentially in just a few years. Most studies have focused on mammalian models as their relevance to human health is widely established. However, evidence is accumulating that insect behavior may be governed by molecular mechanisms that are partly homologous to those of mammals, ...

Abstract:
... Wind is an important yet understudied environmental influence on foraging behaviour. We investigated the direct and indirect effects of wind on foraging worker honey bees, Apis mellifera. Bees were trained to an array of artificial flowers providing nectar rewards in a location sheltered from natural wind. To examine the direct effect, fans produced four different wind speeds between 0 and 3m/s at ...

Abstract:
... A better knowledge of the behaviors that reduce traffic congestions is essential to understand the success of the trail system despite of costs. Leaf-cutting ants use a trunk-trail system to transport leaf fragments into their nests. Some ants carry extra-large leaf fragments and walk slower than the rest of laden workers, thus slowing the ant column behind them. Here we experimentally address whe ...

Abstract:
... Feeding is fundamental to any heterotroph organism; in its role to quell hunger it overrides most other motivational states. But feeding also literally opens the door to harmful risks, especially for a saprophagous animal like Drosophila; ingestion of poisonous substrate can lead to irreversible damage. Thus feeding incorporates a series of steps with several checkpoints to guarantee that the inge ...

Abstract:
... When ants encounter a previously unexplored area, a variety of search patterns are possible. Previous studies have found that subsequent individuals tend to follow those that have gone before. This suggests that ants leave signature marks as they walk, independent of having encountered food, and that others recognize these and follow. This experiment tested if Argentine ants (Linepithema humile) a ...

Abstract:
... The dynamic terminal investment threshold model posits that the propensity of an individual to terminally invest in response to an immediate survival threat, such as an infection, depends on other factors that alter an individual's residual reproductive value. Here, we explore the potential for dynamic terminal investment in burying beetles, insects that inter small vertebrate carcasses as the sol ...

Abstract:
... Although the Neotropical territorially dominant arboreal ant Azteca chartifex Forel is very aggressive towards any intruder, its populous colonies tolerate the close presence of the fierce polistine wasp Polybia rejecta (F.). In French Guiana, 83.33% of the 48 P. rejecta nests recorded were found side by side with those of A. chartifex. This nesting association results in mutual protection from pr ...

In addition, this new tool was used to evaluate a novel formulation of metofluthrin for use as ...

Abstract:
... Cockroaches can defend themselves from threats by escape behavior. Although wind-evoked turning in Periplaneta americana is robust, little is known about the turning and translational components of the escape response to looming and localized heat stimuli, especially in other cockroach species. In particular, it has been suggested that the Madagascar hissing cockroach (Gromphadorhina portentosa) l ...

Abstract:
... The ability of animals to explore landmarks in their environment is essential to their fitness. Landmarks are widely recognized to play a key role in navigation by providing information in multiple sensory modalities. However, what is a landmark? We propose that animals use a hierarchy of information based upon its utility and salience when an animal is in a given motivational state. Focusing on h ...

Abstract:
... Aggression toward competitors is a useful measure of resource ownership and defense in animals, but aggressive behavior is costly. Therefore, it is predicted that animals will display aggression only when the expected benefit to individual fitness exceeds the expected cost. In ants, when conspecific individuals belonging to different colonies encounter each other, fighting occurs, seemingly facult ...

The moment-to-moment tasks performed by an individual can change in response to a shift of internal, e.g. body size or age, and external conditions, e.g. the number of workers currently engaged in another task. For this reason, the term “task allocation” is replacing the earlier concept of “division of labor” for describing an invariable association between worker body size and task. In the presen ...
