Synthetic polymer nanocarrier enhances dsRNA stability but not RNAi efficacy in Brassicogethes aeneus

Pest Management Science, EarlyView.
Experimental setup for dsRNA feeding in Brassicogethes aeneus to evaluate the effect of a synthetic polymer nanocarrier on RNAi efficiency. The experiment assessed whether the nanocarrier enhances RNAi after oral dsRNA delivery. (a) Stability of dsRNA–nanocarrier complexes was tested in simulated gut conditions. (b) Gene expression of αCOP and dre4 was

Evaluation and possible mechanism of beet armyworm (Spodoptera exigua Hubner) resistance to chlorpyrifos and their sensitivity to neem oil insecticides

Open Agriculture, 2020
The uncontrolled and excessive use of insecticides on Spodoptera exigua can cause resistance. The aim of this study is to test resistance of S. exigua to chlorpyrifos and determine the possible mechanism of resistance to S. exigua.

Galleria mellonella (L.) (Pyralidae) und Spodoptera exigua (Hübner) (Noctuidae): Wirkungsunterschiede zwischen XenTari® (Bacillus thuringiensis aizawai), NeemAzal T/S® und ihren Kombinationen [PDF]

, 2008
Both, G. mellonella and S. exigua, are most important pests in tropical countries. G. mellonella has five to six generations per year (Abid et al. 1997; Ali 1996), there, and feeding in bee combs they find, besides wax, residues of honey, insect skin and

Imperfection works: Survival, transmission and persistence in the system of Heliothis virescens ascovirus 3h (HvAV-3h), Microplitis similis and Spodoptera exigua [PDF]

, 2016
Ascoviruses are insect-specific large DNA viruses that mainly infect noctuid larvae, and are transmitted by parasitoids in the fields. Heliothis virescens ascovirus 3h (HvAV-3h) has been recently isolated from Spodoptera exigua, without parasitoid vector

Control failure risk, resistance and enzymatic activity of neurotoxic insecticides in Brazilian populations of Leucoptera coffeella (Lepidoptera: Lyonetiidae)

Pest Management Science, EarlyView.
Bioassays of 36 Leucoptera coffeella populations revealed resistance to neurotoxic insecticides, control failures of ≤62.9% and enzyme activity variation, with particularly high GST and low AChE levels. Abstract Background Leucoptera coffeella is a key pest of coffee crops in Brazil, causing significant damage by mining coffee leaves.

Increased RNAi efficacy in Spodoptera exigua via the formulation of dsRNA with guanylated polymers [PDF]

, 2018
Lepidoptera comprise some of the most devastating herbivorous pest insects worldwide. One of the most promising novel pest control strategies is exploiting the RNA interference (RNAi) mechanism to target essential genes for knockdown and incite toxic ...

Treatment of cotton with plant growth‐promoting rhizobacteria consortium alters host location and oviposition of Spodoptera exigua

Pest Management Science, EarlyView.
Two plant‐growth promoting rhizobacteria (PGPR) consortia (AU8 and TX1) induced a deterrence of host plant location and oviposition behavior of Spodoptera exigua females in both susceptible and resistant cotton plants. Most of the volatile organic compounds (VOCs) increased in PGPR‐treated plants compared to untreated plants. # indicates treatments not
