Freezing for control of stored-product psocids

Journal of Stored Products Research, 2017
Abstract A series of studies was conducted by exposing young and old eggs, nymphs, and adults of the psocids Liposcelis bostrychophila (Badonnel), L. paeta (Pearman), L. decolor (Pearman), and L. entomophila (Enderlein) to −18 °C for various time intervals.

Biology and Management of Psocids Infesting Stored Products

Annual Review of Entomology, 2014
Previously regarded as minor nuisance pests, psocids belonging to the genus Liposcelis now pose a major problem for the effective protection of stored products worldwide. Here we examine the apparent biological and operational reasons behind this phenomenon and why conventional pest management seems to be failing. We investigate what is known about the

Susceptibility of stored-product psocids to aerosol insecticides. [PDF]

J Insect Sci, 2012
The efficacies of commercial methoprene and esfenvalerate aerosols for control of stored-product psocid pests were evaluated in simulated field studies. The efficacies of methoprene, esfenvalerate EC, the carrier Isopar-M™, and a combination of methoprene and esfenvalerate aerosols for control of Liposcelis decolor (Pearman) (Psocoptera: Liposcelididae)

Involvement of Methoprene-tolerant and Krüppel homolog 1 in juvenile hormone-mediated vitellogenesis of female Liposcelis entomophila (End.) (Psocoptera: Liposcelididae). [PDF]

Arch Insect Biochem Physiol, 2023
A graphical summary of this study and a model of the role of juvenile hormone (JH) signaling in the reproduction of Liposcelis entomophila. JH signaling induces reproduction by enhancing the expression of Vg through Met and Kr‐h1. Blocking JH signaling by knockdown with Met and Kr‐h1, which inhibits Vg expression and affects reproduction, can provide ...

Novel Foraging Behaviors of an Urban Bird, the Light-Vented Bulbul (<i>Pycnonotus sinensis</i>). [PDF]

Ecol Evol
Light‐vented Bulbul (Pycnonotus sinensis) were observed foraging on tree trunks in a woodpecker‐like manner. Light‐vented Bulbuls foraged on insect aggregations under artificial street light. Our findings provide new insights into possible behavioral adaptation strategies of Light‐vented Bulbuls to urban environments. ABSTRACT Urban environments expose

Phylogenomics of the family Lachesillidae (Insecta: Psocodea: Psocomorpha)

Systematic Entomology, Volume 48, Issue 2, Page 316-327, April 2023., 2023
Monophyly of bark lice family Lachesillidae never was recovered. Monophyly of the tribe Graphocaeciliini and the genus Lachesilla never were recovered. Systematic position of Eolachesilla chilensis was unstable across different analyses and data sets.

Study on Detection of Psocids Annual Occurrence in Wheat Flour Warehouse in Guangzhou

Liang you shipin ke-ji, 2020
Psocids occurrence was detected in flour warehouse from March-2017 to February-2018 by a corrugated board trap. The location of psocids and its relationship with temperature and humidity were analyzed by geostatistics contour mapping technology.

Limited sex differences in plastic responses suggest evolutionary conservatism of thermal reaction norms: A meta‐analysis in insects

Evolution Letters, Volume 6, Issue 6, Page 394-411, December 2022., 2022
Abstract Temperature has a profound effect on the growth and development of ectothermic animals. However, the extent to which ecologically driven selection pressures can adjust thermal plastic responses in growth schedules is not well understood. Comparing temperature‐induced plastic responses between sexes provides a promising but underexploited ...

Dietary diversity of multiple shorebird species in an Asian subtropical wetland unveiled by DNA metabarcoding

Environmental DNA, Volume 4, Issue 6, Page 1381-1396, November 2022., 2022
Despite previous studies that analyzed the foraging niches of shorebirds worldwide, the dietary niche dynamics of shorebirds coexisting in Asia are very poorly known. This study is therefore the early few that aim to unveil the trophic organization of shorebirds in a subtropical wetland within the EAAF.

Effects of Dehumidification on the Survivorship of Four Psocid Species [PDF]

Journal of Economic Entomology, 2021
AbstractPsocids are damaging stored-product pests. In this study, eggs and early-instar nymphs, adults, and all life stages of Liposcelis entomophila, L. decolor, L. bostrychophila, and L. paeta were subjected to 43, 50, or 75% (Control) relative humidity (RH) for 2, 4, 6, 8, 10, 12, 14, or 16 d at 30.0°C. All adults of these species died within 8 d at
