Transcriptome analysis and systemic RNAi response in the African sweetpotato weevil (Cylas puncticollis, Coleoptera, Brentidae [PDF]

, 2015
The African sweetpotato weevil (SPW) Cylas puncticollis Boheman is one of the most important constraints of sweetpotato production in Sub-Saharan Africa and yet is largely an uncharacterized insect pest.

Sanitary Logging in the Monarch Butterfly Biosphere Reserve: One Problem, One Legislation but Different Criteria and Different Treatments

Land Degradation &Development, EarlyView.
ABSTRACT Bark beetles are small insects that inhabit the bark of trees. When their population increases excessively, they can weaken the trees and cause their death. In México, federal regulations obligate forest landowners to carry out sanitary logging to control bark beetle outbreaks in adherence to official procedures.

DISTRIBUCIÓN ALTITUDINAL Y ESTACIONAL DE Dendroctonus adjunctus Blandford y Dendroctonus brevicomis Leconte EN COAHUILA, MÉXICO

Revista Fitotecnia Mexicana, 2018
Los bosques de pino (Pinus spp.) de todo el mundo están declinando debido al mal manejo, al cambio climático, incendios y ataques de insectos descortezadores (Dendroctonus spp.). El objetivo de este estudio fue evaluar la abundancia altitudinal y temporal de D. adjunctus y D. brevicomis y su relación con la temperatura y características del rodal.

Meteorological versus spatial drivers of the spatial synchrony of forest insect pest outbreaks in North America

Oikos, EarlyView.
Spatial synchrony of population fluctuations has major consequences for the impacts of forest insect pest outbreaks at regional scales. We tested the predictions that the strength and drivers of this synchrony would differ among species according to their dispersal abilities and feeding guilds.

The Southern Pine Beetle Dendroctonus frontalis (Coleoptera: Curculionidae: Scolytinae)

EDIS, 2022
The southern pine beetle (SPB), Dendroctonus frontalis Zimmermann, has been the most economically important forest insect in the pine timber industry in the southern United States. From 1960 through 1990, the bark beetle caused economic losses estimated

Host tree preference and performance of the Eurasian spruce bark beetle (Ips typographus) on Scots pine

Pest Management Science, EarlyView.
Ips typographus showed lower reproductive output in an occasional host (Pinus sylvestris) under laboratory conditions, and did not prefer its main host (Picea abies) over P. sylvestris in two‐choice bioassays. Abstract BACKGROUND The Eurasian spruce bark beetle, Ips typographus, is one of the most serious pests of Norway spruce (NS, Picea abies), with ...

Silencing of juvenile hormone‐related genes through RNA interference leads to molt failure and high mortality in the spongy moth

Insect Science, EarlyView.
The feasibility of using RNA interference to control the globally important quarantine pest, the spongy moth. Targeting genes related to JHs play an important role in the growth and development of insects. First, the open reading frames (ORFs) of Ldjhamt and Ldjheh were identified and characterized, and the target genes were cloned and double‐stranded ...

A Plant‐Based Platform for the Production of Bark Beetle Pheromones

Plant Biotechnology Journal, EarlyView.
ABSTRACT Bark beetle species of the genera Ips and Dendroctonus represent a threat to forests in both North America and Europe. Under normal circumstances, these beetles recycle dying trees into nutrients, but under certain conditions, growing populations can overcome healthy tree defenses and cause severe economic loss in forestry.
