Host exploitation behavior in two hyperparasitoids, Lysibia nana and Gelis agilis, was compared in single cocoon clusters of their primary parasitoid host, Cotesia glomerata. L. nana reproduces sexually, is fully winged, does not host-feed ...
The Old Ladies of the Seed Harvester ant Pogonomyrmex Rugosus: Foraging Performed by Two Groups of Workers [0.03%]
种子收获蚁 pogonomyrmex rugosus 的“老女工”:两种工蚁执行采集任务

We examined temporal polyethism in Pogonomyrmex rugosus, predicting a pattern of decreasing age from foragers to nest maintenance workers to individuals that were recruited to harvest a temporary food source. Nest maintenance workers were y...
Parasite Lost: Chemical and Visual Cues Used by Pseudacteon in Search of Azteca instabilis [0.03%]
伪失寄生:Pseudacteon 寻找Azteca instabilis 时使用的化学和视觉线索

Kaitlyn A Mathis
An undescribed species of phorid fly (genus: Pseudacteon) parasitizes the ant Azteca instabilis F Smith, by first locating these ants through the use of both chemical and visual cues. Experiments were performed in Chiapas, Mexico to examine...
Modeling the Adaptive Role of Negative Signaling in Honey Bee Intraspecific Competition [0.03%]
蜂类种内竞争中负信号适应性作用的建模分析
Brian R Johnson,James C Nieh
Brian R Johnson
Collective decision making in the social insects often proceeds via feedback cycles based on positive signaling. Negative signals have, however, been found in a few contexts in which costs exist for paying attention to no longer useful info...
Does Imprecision in The Waggle Dance Fit Patterns Predicted by The Tuned-Error Hypothesis? [0.03%]
蜜蜂摇摆舞的不精确性符合调整误差假设预测的模式吗?
David A Tanner,P Kirk Visscher
David A Tanner
The waggle dance of the honey bee is used to recruit nest mates to a resource, though direction indicated for a resource may vary greatly within a single dance. Some authors suggest that this variation exits as an adaptation to distribute r...
Large Numbers of Matings Give Female Field Crickets a Direct Benefit but not a Genetic Benefit [0.03%]
交配次数对雌性蟋蟀的直接影响但没有基因层面的影响

Female crickets can potentially gain both direct and indirect benefits from mating multiple times with different males. Most studies have only examined the effects of small numbers of matings, although female crickets are capable of mating ...
Local Competition Between Foraging Relatives: Growth and Survival of Bruchid Beetle Larvae [0.03%]
觅食亲属之间的局部竞争:谷蠹幼虫的生长和存活

Kin selection theory states that when resources are limited and all else is equal, individuals will direct competition away from kin. However, when competition between relatives is completely local, as is the case in granivorous insects who...
Gender Specific Brood Cells in the Solitary Bee Colletes halophilus (Hymenoptera; Colletidae) [0.03%]
雄蜂和雌蜂特异性巢室——以 Halophilia 土蜂为例

Eveline F Rooijakkers
We studied the reproductive behaviour of the solitary bee Colletes halophilus based on the variation in cell size, larval food amount and larval sex in relation to the sexual size dimorphism in this bee. Brood cells with female larvae are l...
Effects of Brood Pheromone Modulated Brood Rearing Behaviors on Honey Bee (Apis mellifera L.) Colony Growth [0.03%]
蜂王浆调节蜂巢繁殖行为对意大利蜜蜂(Apis mellifera L.)种群增长的影响

A hallmark of eusociality is cooperative brood care. In most social insect systems brood rearing labor is divided between individuals working in the nest tending the queen and larvae, and foragers collecting food outside the nest. To place ...
Surplus Killing by Predatory Larvae of Corethrella appendiculata: Prepupal Timing and Site-Specific Attack on Mosquito Prey [0.03%]
Corethrella appendiculata 的捕食性幼虫的剩余杀戮作用:蚊子猎物的化蛹时间和定点攻击行为

L P Lounibos et al.
Surplus or 'wasteful' killing of uneaten prey has been documented in the fourth larval instar of various species of the mosquito genus Toxorhynchites that occur in treeholes and other phytotelmata. Here we document surplus killing by the pr...
