Tracking malathion resistance in Spanish Ceratitis capitata populations: prevalence of resistance alleles/haplotypes before and after the withdrawal of malathion

open access: yesPest Management Science, EarlyView.
The mutation G328A (R allele) and a novel heterogeneous duplication of the acetylcholinesterase gene (RS haplotype, one of the copies bearing the mutation G328A and the other copy non‐mutated), both accounting for malathion resistance, were widely distributed in Spanish Ceratitis capitata populations when malathion was used (2003–2008). Their frequency

Local outbreaks of Operophtera brumata and Operophtera fagata cannot be explained by low vulnerability to pupal predation [PDF]

open access: yes, 2013
One of the unresolved questions in studies on population dynamics of forest Lepidoptera is why some populations at times reach outbreak densities, whereas others never do.

Rearing and Description of the Early Stages of the Nearctic Species of Peridea, with Special Reference to P. Basitriens (Lepidoptera: Notodontidae) [PDF]

open access: yes, 2017
Excerpt: The genus Peridea Stephens, according to Forbes (1948), is composed of two subgenera: Lophodonta Packard and Peridea. To the former belong the two species, angulosa (J.E. Smith, 1797) and ferruginea Packard, 1864; to the latter only one species,

Virulence and biocontrol potential of entomopathogenic nematodes against soil‐dwelling stages of the small hive beetle under laboratory and semi‐field conditions

open access: yesPest Management Science, EarlyView.
Entomopathogenic nematodes (EPNs) are virulent against multiple life stages of Aethina tumida in the laboratory. EPNs significantly reduce adult emergence in natural and autoclaved sterile soil under semi‐field glasshouse conditions. Abstract BACKGROUND The small hive beetle (SHB; Aethina tumida) is a significant pest affecting honey bees and the ...

Division of labour and risk taking in the dinosaur ant, Dinoponera quadriceps [PDF]

open access: yes, 2013
The success of social insects can be largely attributed to division of labour. In contrast to most social insects, many species with simple societies contain workers which are capable of sexual reproduction.

The immature stages of Paramallocera hirta kirby, 1818 (Coleoptera: Cerambycidae: Elaphidionini)

open access: yesBrazilian Journal of Biology
Last instar larva and pupa of Paramallocera hirta Kirby, 1818 are described and illustrated based on specimens reared in the laboratory from neonate larvae on Eucalyptus globulus ssp. globulus logs and on an artificial diet.

Complementarity between Orius predators improves control of foliar and flower pests

open access: yesPest Management Science, EarlyView.
Orius predators are commonly used against thrips in many crops. Certain species are suggested to be more effective against flower pests, while others may control effectively foliar pests. Here, we show that Orius species combinations may complement each other and effectively control both flower and foliar pests on gerbera.

Development of Eye Colors in Drosophila: Extraction of the Diffusible Substances Concerned [PDF]

open access: yes, 1937
The development of eye color in Drosophila is known to involve special diffusible substances [1,2]. A genetically vermilion (v) eye will develop wild-type eye color if it is supplied with v+ substance by transplantation or by injection of body fluid of ...

Estimating the efficacy and plume reach of semiochemical‐baited traps on the capture of Trogoderma granarium everts

open access: yesPest Management Science, EarlyView.
"Simulated warehouse": In this study, we take the step of testing existing and modified trap designs for Trogoderma after the release of T. granarium exclusively. This work will serve to evaluate trap efficacy, while providing a template for further attractant–kill research. The most effective trap was dome trap.
