Mechanisms, Applications, and Challenges of Insect RNA Interference.

open access: yesAnnual Review of Entomology, 2020
The RNA interference (RNAi) triggered by short/small interfering RNA (siRNA) was discovered in nematodes and found to function in most living organisms.

Herbivory increases diversification across insect clades. [PDF]

open access: yes, 2015
Insects contain more than half of all living species, but the causes of their remarkable diversity remain poorly understood. Many authors have suggested that herbivory has accelerated diversification in many insect clades. However, others have questioned

Integrating biocontrol agents with farmer’s practice: impact on diamondback moth, Plutella xylostella (Linnaeus) (Lepidoptera: Plutellidae) and cabbage yield

open access: yesEgyptian Journal of Biological Pest Control, 2019
A field trial was conducted in a farmer’s field by integrating biocontrol agents, a multiple insecticide tolerant strain (MITs), Trichogramma chilonis and formulation of Bacillus thuringiensis (NBAIR BtG4) with reduced insecticidal spray as a biocontrol ...

Fast and robust learning by reinforcement signals: explorations in the insect brain [PDF]

open access: yes, 2009
We propose a model for pattern recognition in the insect brain. Departing from a well-known body of knowledge about the insect brain, we investigate which of the potentially present features may be useful to learn input patterns rapidly and in a stable ...

Comparative transcriptome analysis of venom glands from Cotesia vestalis and Diadromus collaris, two endoparasitoids of the host Plutella xylostella

open access: yesScientific Reports, 2017
Venoms secreted by the venom gland (VG) of parasitoid wasp help ensure successful parasitism by host immune suppression and developmental regulation. Cotesia vestalis, a larval endoparasitoid, and Diadromus collaris, a pupal endoparasitoid, parasitize ...

Counting insects [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2018
When counting-like abilities were first described in the honeybee in the mid-1990s, many scholars were sceptical, but such capacities have since been confirmed in a number of paradigms and also in other insect species. Counter to the intuitive notion that counting is a cognitively advanced ability, neural network analyses indicate that it can be ...

Interpreting insect declines: seven challenges and a way forward

open access: yesInsect Conservation and Diversity, 2020
Many insect species are under threat from the anthropogenic drivers of global change. There have been numerous well‐documented examples of insect population declines and extinctions in the scientific literature, but recent weaker studies making extreme ...

Collecting \u3ci\u3eNeocurtilla Hexadactyla\u3c/i\u3e, the Northern Mole Cricket (Orthoptera: Gryllidae), in Iowa [PDF]

open access: yes, 2017
(excerpt) The northern mole cricket, Neocurtilla hexadactyla (Perty), is a common insect that is infrequently collected perhaps owing to its burrowing and nocturnal habits.

Highly focused transcriptional response of Anopheles coluzzii to O’nyong nyong arbovirus during the primary midgut infection

open access: yesBMC Genomics, 2018
Background Anopheles mosquitoes are efficient vectors of human malaria, but it is unknown why they do not transmit viruses as well as Aedes and Culex mosquitoes.
