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

open access: yesPest 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

A brief review of the larval rearing techniques of penaeid prawns [PDF]

open access: yes, 1985
As early as half a century ago, Hudinaga successfully spawned and attempted to rear the larvae of Penaeus japonicus. Publications in the 1960 s, 70's and 80's on breakthroughs in larval rearing of one penaeid species after another indicated that ...

Frequency distribution of early-instar larval head widths.

open access: yes, 2012
Three peaks were identified in the distribution of larval head widths to indicate the groupings we used to delineate early instars (roman numerals indicate instars I-III).

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape

open access: yesPest Management Science, EarlyView.
Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

Decrease of fluctuating asymmetry among larval instars in an aquatic, holometabolous insect

open access: yesComptes Rendus. Biologies, 2005
The use of fluctuating asymmetry (FA) to reveal environmental stress in natural populations has been investigated extensively over the past decade. In aquatic ecosystems, many investigations involve amphibiotic insects with larval development stages in freshwater.

Seasonal variation in horizontal and vertical structure of larval fish assemblages off south-western Australia, with implications for larval transport [PDF]

open access: yes, 2007
The coastal ocean off south-western Australia is characterised by the southward-flowing Leeuwin Current, which suppresses the upwelling typically associated with other eastern boundary currents in the southern hemisphere.

Seedling resistance and chemical defenses against Psylliodes chrysocephala: the roles of seed age and sinapinic acid in Sinapis alba and Brassica napus

open access: yesPest Management Science, EarlyView.
The cabbage stem flea beetle (Psylliodes chrysocephala) is a major pest of winter oilseed rape (Brassica napus). We tested B. napus and Sinapis alba seedlings for feeding resistance and underlying chemical defenses. S. alba was least damaged, while metabolite profiles revealed resistance‐linked compounds, highlighting breeding potential for insect ...

Larval instar determination of the pea and bean weevil Sitona lineatus L. (Coleoptera: Curculionidae)

open access: yes, 1984
Head-capsule measurements on larvae of Sitona lineatus (L.) collected on beans (Vicia faba) in southern England in 1980 showed that there were 5 larval instars.

Larval antibiosis to cabbage stem flea beetle (Psylliodes chrysocephala) is absent within oilseed rape (Brassica napus)

open access: yesPest Management Science, EarlyView.
We screened a panel of 98 Brassicaceae genotypes (97 Brassica napus and 1 Sinapis alba) for cabbage stem flea beetle (Psylliodes chrysocephala) larval antibiosis. We found limited evidence for antibiosis across B. napus but consistent antibiosis in S. alba. Brassicaceae relatives may therefore better inform resistance traits for breeding.
