OCCURRENCE OF SPIDER MITES (Prostigmata: Tetrnaychidae) AND PHYTOSEIID MITES (Mesostigmata: Phytoseiidae) AS THEIR POTENTIAL ENEMIES, ON NORWAY SPRUCE (Picea abies (L.)) AND ITS CULTIVARS GROWN IN ORNAMENTAL PLANT NURSERIES IN POLAND

open access: yesActa Scientiarum Polonorum: Hortorum Cultus, 2014
Despite intensive chemical plant protection conducted in ornamental nurseries in Poland, spider mites are still one of problematic pests. In view of increasing resistance of spider mites on acaricides, searching for alternative methods of nursery plants

Mother-Offspring Relations: Prey Quality and Maternal Size Affect Egg Size of an Acariphagous Lady Beetle in Culture

open access: yesPsyche: A Journal of Entomology, 2012
We investigated mother-offspring relations in a lady beetle Stethorus punctillum Weise that utilizes spider mites as prey. Our objectives were to determine if (1) prey quality affects egg size, (2) maternal size correlates with egg size, and (3) egg size

A horizontally transferred bacterial gene for pantothenic acid biosynthesis regulates diapause and reproduction in the spider mite Amphitetranychus viennensis

open access: yesInsect Science, EarlyView.
A bacterial‐derived AvPBL gene encoding a pantothenate‐β‐alanine ligase was identified in Amphitetranychus viennensis. RNAi silencing of AvPBL reduced pantothenic acid production, impairing reproduction and diapause induction, while pantothenic acid supplementation rescued these phenotypes.

Extreme Silk Toughness in Caerostris Spiders Is Limited to Adult Females

open access: yesIntegrative Zoology, EarlyView.
We ask whether species with exceptionally tough silk, like Caerostris bark spiders, show different developmental patterns in silk toughness between ontogenetic stages and sexes. We found that only large females produce exceptionally tough silk with higher initial stiffness, while juvenile females as well as adult and juvenile males produce inferior ...

A new place for stories in conservation

open access: yesConservation Biology, EarlyView.
Abstract Michael Soule writes in his foundational article “What is Conservation Biology?” that “in crisis disciplines, one must act before knowing all the facts; crisis disciplines are thus a mixture of science and art, and their pursuit requires intuition as well as information.” Since this article was published three decades ago, conservation biology

Island invertebrate responses to single‐ and multi‐species invasive rodent eradications

open access: yesConservation Science and Practice, EarlyView.
Eradications of rodents on islands are a powerful tool for conservation, but rarely are the responses of invertebrates quantified post‐eradication, despite being the preferred prey of mice. Here we analyzed pre‐ and post‐eradication invertebrate survey results for two sub‐Antarctic islands where mice had recently been eradicated; Antipodes Island where
