Acaricide Evaluation, 1994 [PDF]

open access: yesArthropod Management Tests, 1995
Abstract This experiment was conducted in a 2.1 acre block of 9-yr-old trees on M 7A rootstock. The trees measured 11.5 ft in height and 10 ft in width and were planted at a spacing of 12 × 18 ft. The experimental design consisted of a single 0.35 acre plot (8 rows × 9 trees/row) for each treatment.

Evolving resistance patterns in Tetranychus urticae and Bemisia tabaci in Greece

open access: yesPest Management Science, Volume 82, Issue 4, Page 3544-3551, April 2026.
Greek populations of T. urticae and B. tabaci exhibit evolving multi‐resistance, confirmed by bioassays and molecular markers, highlighting the urgent need for evidence‐based resistance monitoring in IPM. Abstract BACKGROUND Pesticide resistance in agricultural pests remains a major barrier to effective and sustainable crop protection.

An RNA interference biopesticide reduces reproduction of the honey bee parasite Varroa destructor by down‐regulating embryo development pathways

open access: yesPest Management Science, Volume 82, Issue 3, Page 2694-2707, March 2026.
Varroa destructor mites exposed to dsRNA specific in sequence to a V. destructor calmodulin gene significantly effected gene expression of adult female mites sampled 5 days after entering a honey bee brood cell to reproduce. Significantly down‐regulated genes included Calmodulin and were associated with calcium ion binding and embryo developmental ...
