Subtractive Hybridization Strategy Using Paramagnetic Oligo(dT) Beads and PCR

open access: yesBioTechniques, 1996
Subtractive hybridization has been widely used for the identification of differentially expressed genes. Here we describe a simple, sensitive strategy of subtractive hybridization that involves binding the driver poly(A)+ RNA pool to paramagnetic ...

Defecation in preparation for ecdysis drives microplastic clearance in cricket nymphs

open access: yesPhysiological Entomology, EarlyView.
In preparation for ecdysis, cricket nymphs cease feeding and gradually clear their gut contents via frass production, which removes most ingested MPs from their digestive tract. Following exoskeletal moulting, the foregut lining, including any remaining MPs, is shed and excreted alongside frass approximately 6 h later.

The Potential for Pest Management Using Plant‐Derived Signaling Compounds

open access: yesEcological Research, Volume 41, Issue 5, September 2026.
Plant‐derived signaling compounds mediate ecological interactions among plants, herbivores, their natural enemies, and neighboring plants. This graphical summary highlights three approaches to leveraging such ecological interactions for environmentally benign pest management: (1) Recruitment of natural enemies: Using herbivory‐induced plant volatiles ...

Effects of Coloration on Parasitism, Predation, and Field Survivorship of the Tobacco Hornworm, Manduca sexta (L.)

open access: yes, 1993
Studies were conducted to determine the effect of pigmentation on the field survivorship of larvae of the tobacco hornworm, Manduca sexta (L.). Larvae of the white-mutant tobacco hornworm were found to have a lower mean survival rate as compared with ...

Wheat fertilization affects oviposition preference of wheat midge, Sitodiplosis mosellana (Géhin) (Diptera: Cecidomyiidae)

open access: yesPest Management Science, Volume 82, Issue 7, Page 6740-6748, July 2026.
Wheat fertilization increased plant growth, nitrogen and protein levels, influencing the wheat volatile profile and affecting female wheat midge choice to lay eggs. This could partly result from the observed changes in the VOC profile. Abstract BACKGROUND In Canada, the orange wheat blossom midge (hereafter called wheat midge), Sitodiplosis mosellana ...

Starvation-Induced Changes to the Midgut Proteome and Neuropeptides in Manduca sexta

open access: yesInsects
Starvation is a complex physiological state that induces changes in protein expression to ensure survival. The insect midgut is sensitive to changes in dietary content as it is at the forefront of communicating information about incoming nutrients to the
