Numerical Reduction of Instars in the Metamorphosis of Euphausids [PDF]

open access: yesNature, 1926
THE development of an animal from the zygote up to the adult condition is usually accompanied by a more or less regular and continuous increase in size. In the case of the Arthropoda, however, the enclosure of the body in a hard inextensible layer of chitin renders this impossible, and in accordance with this the chitinous exoskeleton is shed from time

Evaluating antibiosis resistance to cabbage aphid (Brevicoryne brassicae L., 1758) in vegetable brassicas (Brassica oleracea L.) and related C‐genome brassica species

open access: yesPest Management Science, EarlyView.
Nineteen Brassica accessions were screened for antibiosis resistance to Brevicoryne brassicae. Significant variation in resistance was identified. Detailed bioassays suggest that varietal effects upon aphid pre‐reproductive period conferred observed resistance.

Injection but not ingestion of a mixed virus suspension in Queensland fruit fly (Bactrocera tryoni) shifts persistent covert infection to acute pathology

open access: yesPest Management Science, EarlyView.
Covert and persistent infections with multiple insect‐specific viruses are common in pest fruit flies and may affect pest management strategies. Our study investigated the host effects and viral loads of cripavirus and iflavirus as persistent infections in Queensland fruit fly, and after injection and ingestion of a mixed virus suspension containing ...

Effect of three insect-resistant maizes expressing Cry1Ie, Cry1Ab/Cry2Aj and Cry1Ab on the growth and development of armyworm Mythimna separata (Walker)

open access: yesJournal of Integrative Agriculture, 2020
Three transgenic maize events (IE09S034, Shuangkang 12–5 and C0030.3.5) produced Cry1le, Cry1Ab/Cry2Aj and G10-EPSPS, Cry1Ab and EPSPS, respectively, all of which target the Asian corn borer.

RNAi‐mediated gene silencing of a 26S proteasome subunit increases mortality of the Japanese beetle Popillia japonica

open access: yesPest Management Science, EarlyView.
We propose the regulatory particle non‐ATPase subunit 6 of the 26S proteasome as a first good promising RNA interference target candidate to control the Japanese beetle Popillia japonica. This will help to optimize a double‐stranded RNA insecticide against this priority pest with low off‐target effects on pollinators on a gene sequence‐based prediction.

Evidence of Cuticle Chemicals of Heortia vitessoides (Lepidoptera: Crambidae) Larvae Influencing the Aggregation Behavior of Conspecific Larvae

open access: yesInsects
Heortia vitessoides (Lepidoptera: Crambidae) is a severe pest of Aquilaria plants, which produce high-priced agarwood. The larval stage of this pest is gregarious, usually forming large aggregates during young instars and becoming solitary during the ...

Prey preference of Eupeodes corollae (Dip.: Syrphidae) on different nymphal instars of Brevicoryne brassicae (Hem.: Aphididae) [PDF]

open access: yesنامه انجمن حشره‌شناسی ایران, 2012
The prey stage preferences of the second and third instar larvae of syrphid fly species Eupeodes corollae (Fabricius) on different nymphal instars of Brevicoryne brassicae (L.) were studied in no-choice and choice conditions (25 ± 2°C, 65 ± 5% R.H ...
