Are populations of European earwigs, Forficula auricularia, density dependent?
TLDR
A 2‐year phenological study in several apple and pear orchards in Belgium showed a significant displacement of third instars during the second brood in relation to the presence of adults, and observed a yearly population crash at the time of moulting into adults. Expand
Interspecific Trail Following and Commensalism Between the Ponerine Ant Gnamptogenys menadensis and the Formicine Ant Polyrhachis rufipes
TLDR
The first report of commensalism between a ponerine and a formicine ant is reported, and the workers of Polyrhachis rufipes show a typical aggressive antennal boxing to which Gnamptogenys reacts with a submissive behavior. Expand
Performance of the predatory mite Amblydromalus limonicus on factitious foods
TLDR
Diet significantly influenced the size of A. limonicus females as measured by the distance between specific setae on the dorsal shield of the idiosoma, and the application of the investigated food sources to sustain a colony of predatory mites upon their release in a greenhouse crop is discussed. Expand
The energetic cost of reproductive conflicts in the ant Pachycondyla obscuricornis.
TLDR
This paper estimated the energetic costs associated with the regulation of worker reproduction in the ponerine ant Pachycondyla obscuricornis using the total CO2 emission of a colony as a measure, and presented the first quantification of energetic costs of aggressive behavior regulating reproduction in ants. Expand
Diet-dependent cannibalism in the omnivorous phytoseiid mite Amblydromalus limonicus
TLDR
The rate of cannibalism was dependent on the food source offered, but always resulted in reduced population growth rates and cannibalistic behavior should be taken into account when selecting food sources for mass rearing of A. limonicus or supporting its populations in the field. Expand
Alternating temperatures affect life table parameters of Phytoseiulus persimilis, Neoseiulus californicus (Acari: Phytoseiidae) and their prey Tetranychus urticae (Acari: Tetranychidae)
TLDR
The results indicate that thermal responses of the studied phytoseiid predators to alternating temperature regimes used in energy saving strategies in glasshouse crops may have consequences for their efficacy in biological control programs. Expand
Comparative Survey of Abdominal Gland Secretions of the Ant Subfamily Ponerinae
TLDR
All of the 27 known analyses of Dufour glands, 21 analyses of venom glands, and 4 of pygidial glands of workers of ponerine ant species have been brought together in order to seek some pattern in the type of glandular contents. Expand
Queens and major workers of Acanthomyrmex ferox redistribute nutrients with trophic eggs
TLDR
The large proportion of trophic egg production by the queen and soldiers is quite remarkable, since ant queens are expected to focus entirely on reproduction and majors, which have a defensive function in many species, to be sterile. Expand
Policing behaviour towards virgin egg layers in a polygynous ponerine ant
TLDR
The results show that sterile workers discriminate against new egg layers, given that their ovaries are not as developed as those of gamergates, and Olfactory detection of different levels of ovarian activity thus appears possible. Expand
Characterization and taxonomic reassessment of the box blight pathogen Calonectria pseudonaviculata, introducing Calonectria henricotiae sp. nov.
TLDR
This study determined the genetic diversity in a collection of 234 Calonectria isolates from diseased Buxus plants, originating from 15 countries and four continents and identified a second phylogenetic species causing box blight. Expand
