Malaria mosquito antimicrobial defence requires immunity and detoxification gene regulation by Lola. [PDF]

Insect Mol Biol
Malaria mosquito antimicrobial defence requires upregulation of lola. Attenuation of lola in the midgut of Anopheles albimanus mosquitoes inhibits the upregulation of immunity genes induced by challenge. Putative target genes of the Lola transcription factor were revealed by lola attenuation, including Cecropin‐C, Draper, PPAF2, Clip‐domain serine ...

Invasion of midgut epithelial cells by a persistently transmitted virus is mediated by sugar transporter 6 in its insect vector

PLoS Pathogens, 2018
Insect transmission is obligatory for persistently transmitted viruses because the vector insect is the only means of virus spread in nature. The insect midgut is the first major barrier limiting virus acquisition, but the mechanisms by which viruses are

Characterization of Cry2Ab2 resistance in Crocidosema sp. (Lepidoptera: Tortricidae): resistance selection, inheritance, cross‐resistance patterns, and fitness costs

Pest Management Science, EarlyView.
This article reports the first characterization of Cry2Ab2 resistance in Crocidosema sp. Resistance appears to be autosomal and incompletely recessive, with a major‐gene contribution and potential involvement of additional genetic factors, and did not confer cross‐resistance to Cry1Ac or Cry1A.105. Abstract BACKGROUND The soybean bud borer, Crocidosema

Diverse laboratory colonies of Aedes aegypti harbor the same adult midgut bacterial microbiome

Parasites & Vectors, 2017
Host-associated microbes, collectively known as the microbiota, play an important role in the biology of multicellular organisms. In mosquito vectors of human pathogens, the gut bacterial microbiota influences vectorial capacity and has become the ...

Inheritance and fitness costs of field‐evolved resistance to Gpp34/Tpp35Ab1 corn by western corn rootworm, Diabrotica virgifera virgifera (Coleoptera: Chrysomelidae)

Pest Management Science, EarlyView.
Field‐evolved resistance to Gpp34/Tpp35Ab1 corn in two western corn rootworm strains was inherited in a non‐recessive manner and was associated with fitness costs. Abstract BACKGROUND The western corn rootworm, Diabrotica virgifera virgifera LeConte, is among the most serious pests of corn in the United States, and an invasive pest in parts of Europe ...

A cyclic GMP signalling module that regulates gliding motility in a malaria parasite [PDF]

, 2009
The ookinete is a motile stage in the malaria life cycle which forms in the mosquito blood meal from the zygote. Ookinetes use an acto-myosin motor to glide towards and penetrate the midgut wall to establish infection in the vector.

Long-term live imaging of the Drosophila adult midgut reveals real-time dynamics of division, differentiation and loss

eLife, 2018
Organ renewal is governed by the dynamics of cell division, differentiation and loss. To study these dynamics in real time, we present a platform for extended live imaging of the adult Drosophila midgut, a premier genetic model for stem-cell-based organs.

Oral RNAi reduces survival and grain loss in Rhyzopertha dominica, including phosphine‐resistant populations

Pest Management Science, EarlyView.
Oral delivery of dsRNA targeting essential genes reduces adult survival and grain damage in Rhyzopertha dominica, including highly phosphine‐resistant populations. These findings support RNAi as a complementary mode‐of‐action for resistance management and postharvest protection in stored‐grain systems. Abstract BACKGROUND Phosphine fumigation remains a

An insight into the sialome, mialome and virome of the horn fly, Haematobia irritans

BMC Genomics, 2019
Background The horn fly (Haematobia irritans) is an obligate blood feeder that causes considerable economic losses in livestock industries worldwide. The control of this cattle pest is mainly based on insecticides; unfortunately, in many regions, horn ...

Commercial Product Based on Metarhizium Anisopliae Affects Survival, Midgut Morphology, and Behavior in the Stingless Bee Scaptotrigona depilis (Hymenoptera: Apidae)

Environmental Toxicology, EarlyView.
ABSTRACT Brazilian social stingless bees are important pollinators and producers of honey, wax, royal jelly, propolis, and other products. These species are experiencing a population decline, attributed to different factors, such as the excessive use of pesticides.
