Assessing pest control treatments from phenology models and field data

Pest Management Science, Volume 81, Issue 4, Page 1851-1859, April 2025.
Theoretical effect of two larvicide sprays, two delayed larvicide sprays that follow an oil treatment, mating disruption, and mating disruption plus four virus sprays on codling moth larva (brown for treated versus pink for untreated) and adult (dark green for treated versus light green for untreated) phenology.

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

نامه 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 ...

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

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

Insects
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 ...

New species of Homidia (Collembola, Entomobryidae) from eastern China with description of the first instar larvae

ZooKeys, 2011
Morphology of the first instar larvae of Collembola has considerably taxonomical and phylogenetic significance. We describe the first instar larvae for the first time in Homidia.

A UAV‐based deep learning pipeline for intertidal macrobenthos monitoring: Behavioral and age classification in Tachypleus tridentatus

Remote Sensing in Ecology and Conservation, EarlyView.
The endangered tri‐spine horseshoe crab (Tachypleus tridentatus), a “living fossil” crucial to coastal ecology and biomedical research, is experiencing severe population declines. Effective conservation requires efficient monitoring, which traditional methods cannot deliver at scale. We develop an integrated UAV deep learning framework tailored to this

Study of some biological aspects of the blowfly Chrysomya albiceps (Wiedemann 1819) (Diptera: Calliphoridae) in Jeddah, Saudi Arabia

Egyptian Journal of Forensic Sciences, 2016
We reared Chrysomya albiceps (Wiedemann 1819) unadult stages (first larval instar, second larval instar, third larval instar and pupal stage) under four constant temperatures. Results proved that increasing temperature from 20 to 25, 30 and 35 °C reduced

RELATIVE SUSCEPTIBILITY TO ARSENIC IN SUCCESSIVE INSTARS OF THE SILKWORM [PDF]

Journal of General Physiology, 1926
The susceptibility of the silkworm to arsenic decreases during its larval development. Relative susceptibility may be expressed numerically as a ratio of areas under dosage-effect curves.
