Herbivore induction of the glucosinolate-myrosinase defense system: major trends, biochemical bases and ecological significance [PDF]
, 2009 Like many other plant defense compounds, glucosinolates are present constitutively in plant tissues, but are also induced to higher levels by herbivore attack.

Selection, counterselection, and conditional gene expression for genetic biocontrol of insects
Insect Science, EarlyView.Selection, counterselection, and conditional expression can be used for sex separation. Selection (S) and counterselection (CS) genes are linked to the sex chromosomes (e.g., the X and Y chromosomes) to confer sex‐specific selection or counterselection based on the presence or absence of the S or CS genes.

In vitro culture of the fastidious bacteria Candidatus Liberibacter asiaticus in association with insect feeder cells [PDF]
, 2011 Ca. Liberibacter asiaticus (LAS) is vectored by psyllids and is able to proliferate inside the insect. We therefore hypothesize that insect cells could act like feeder cells, providing nutrients in a continuous way and a favorable environment to the ...

Neoclassical development of genetic sexing strains for insect pest and disease vector control
Insect Science, EarlyView.The sterile insect technique has been effectively used for decades, and an important component is the availability of sex separation systems, in particular genetic sexing strains. Classical approaches, such as irradiation‐induced chromosomal translocations, have yielded stable strains for species like the Mediterranean fruit fly.

Reduced fertilization regimes could boost biocontrol service without reducing crop yield
Insect Science, EarlyView.Fertilization level influences pest control effectiveness in tomato crops. High fertilization increases plant growth and aphid density but reduces the performance of the parasitoid Aphidius ervi. In contrast, the predator Adalia bipunctata maintains consistent aphid suppression regardless of fertilization regime.

Insect Feeding Assays with Spodoptera exigua on Arabidopsis thaliana
Bio-Protocol, 2020 Plant-insect interaction is an important field for studying plant immunity. The beet armyworm, Spodoptera exigua, is one of the best-known agricultural pest insects and is usually used to study plant interactions with chewing insects. Here, we describe a
