Female Sexual Signaling in a Capital Breeder, the European Glow-Worm Lampyris noctiluca J. Insect Behav. (IF 0.991) Pub Date : 2021-01-15 Gautier Baudry, Juhani Hopkins, Phillip C. Watts, Arja Kaitala
Theory predicts that because costs constrain female sexual signaling, females are expected to have a low signaling effort that is increased with passing time until mating is secured. This pattern of signaling is expected to result from females balancing the costs associated with a higher than optimal signaling effort and those costs associated with a low signaling effort that increase the likelihood

Sex Investment Ratio and Split Sex Ratio in the Fission-Performing Ant Cataglyphis tartessica J. Insect Behav. (IF 0.991) Pub Date : 2021-01-09 Fernando Amor, Xim Cerdá, Raphaël Boulay
Inclusive fitness theory predicts that the sex investment ratio should be female biased in social insects with haplodiploidy-generated relatedness asymmetry (between females and males and also among females). However, this ratio should become male biased if related females are competing with each other for resources, as it is predicted by local resource competition hypothesis. This specific situation

Does the Presence of Other Egg Rafts and Conspecific Larvae Encourage Oviposition by the Mosquito, Culex sitiens (Diptera: Culicidae)? J. Insect Behav. (IF 0.991) Pub Date : 2021-01-06 Derek Roberts
Mosquitoes include many major disease vectors and are often controlled in their aquatic larval stage, since they are living in defined habitats. However, non-chemical methods of control are influenced by the female oviposition behavior, and this is affected by many factors. Many mosquito species choose to oviposit on water containing egg raft pheromones (which have thus been used in control), showing

Behavior in Transition: Recovery of Behavior by an Obligate Parasitic Ant ( Formica subintegra) Following Host Removal J. Insect Behav. (IF 0.991) Pub Date : 2020-05-29 Amber N. Hunter; Alicia Mathis
Dulosis is a type of social parasitism in which a parasitic ant has become dependent on captured workers (hosts) of a closely related species. Dulosis can be either facultative or obligate depending on the degree of dependence on host workers. As parasites become more specialized over evolutionary time, their domestic abilities degenerate until they become unable to survive without the host. However

Social Cues of Future Sperm Competition Received during Development Affect Learning in Adult Male Fruit Flies, Drosophila melanogaster J. Insect Behav. (IF 0.991) Pub Date : 2019-05-15 Laurin S. McDowall; James Rouse; Steven M. Sait; Amanda Bretman
The social environment provides males with information about the likelihood of reproductive competition. However, social context can be highly variable, and males must track their environment in order to alter reproductive investment appropriately. In addition to using information gained as adults to adjust reproductive strategies, males can use cues in early life to anticipate future mating competition

Tasks Performed by Different Groups of Foragers and Regulation of Foraging Activity in the Mediterranean Harvest Ant Messor wasmanni (Hymenoptera, Formicidae) J. Insect Behav. (IF 0.991) Pub Date : 2019-04-28 D. D’Eustacchio; L. Solida; A. Profico; M. Centorame; D. A. Grasso; C. Castracani; A. Mori; A. Fanfani
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 present

Foliage Type and Deprivation Alters the Movement Behavior of Late Instar European Gypsy Moth Lymantria dispar (Lepidoptera: Erebidae) J. Insect Behav. (IF 0.991) Pub Date : 2019-04-22 Jacob T. Wittman; Brian H. Aukema
The movement behavior of insects characterizes their ability to disperse, establish, compete, forage, seek mates, and ultimately reproduce. Understanding the movement of invasive insects is particularly important for developing management policies. We conducted laboratory experiments in Minnesota, USA to determine how host type and food deprivation affected the movement of late instars of the European

Analysis of Anemotactic Flight Tendencies of the Spotted Lanternfly ( Lycorma delicatula ) during the 2017 Mass Dispersal Flights in Pennsylvania J. Insect Behav. (IF 0.991) Pub Date : 2019-03-05 Andrew J. Myrick; Thomas C. Baker
Video-recordings were made of adult spotted lanternflies, Lycorma delicatula, taking flight from apple trees in an orchard in northeast Pennsylvania in September, 2017 during a mass dispersal flight event involving thousands of adults. The trajectories of adults flying upwind in straight and level or gradually descending flight allowed them to traverse only up to ca. 40 m in a single flight-bout. Many

Divergence in Time Apportionments of Tongue Protraction and Retraction Phases for Feeding Honey Bee Drones and Workers J. Insect Behav. (IF 0.991) Pub Date : 2019-02-27 Jianing Wu; Huan Weng; Shaoze Yan
Honey bees have three castes, drones, workers, and queens, that accomplish different tasks. In this research, we revealed the divergence in feeding behavior of drones and workers by experimental and theoretical techniques from the perspective of tongue kinematics. We observed the feeding cycles from living drones and workers of Apis mellifera ligustica and introduced a fluid transport model for computing

Pre-Mating Reproductive Isolation in Tiger Beetles (Carabidae: Cicindelinae): an Examination of the Role of Visual and Morphological Feedback J. Insect Behav. (IF 0.991) Pub Date : 2018-12-21 Te K. Jones; William E. Conner
The biological species concept depends on mechanisms isolating reproduction to taxonomically define a species and to explain the disadvantages, and subsequent lack, of hybridization. In co-occurring tiger beetles (Carabidae: Cicindelinae), these between-species barriers are not readily apparent. To understand the characteristics potentially responsible for this isolation, we conducted behavioral and

Choice of Tethering Material Influences the Magnitude and Significance of Treatment Effects in Whitefly Electrical Penetration Graph Recordings J. Insect Behav. (IF 0.991) Pub Date : 2018-12-13 Quentin Chesnais; Kerry E. Mauck
The electrical penetration graphing or electropenetrography (EPG) technique is essential for understanding interactions of hemipteran insects with their host plants. Typically, 10–12.5 μm diameter gold wire is used as the tethering material in EPG studies. This wire was originally chosen based on suitability for aphids, but application of the EPG technique to other insects necessitates testing of alternative
