gnatocerus: Weapon size and insulin-like signalling in the broad-horned flour beetle

Description

Data from an experiment testing how weapon size in insects is controlled by insulin-like peptides. The weapon in question is the enlarged mandibles of the broad-horned flour beetle Gnatocerus cornutus. Larvae were treated with RNAi to knock out a number of candidate ILPs and adult size (elytron width) and weapon size were measured once they had eclosed.

Usage

data("gnatocerus")

Format

A data frame with 144 observations on the following 3 variables.

treatment

The RNAi knockout treatment used. GFP = control, 1-5 ILP are the 5 insulin-like peptides targetted

EW

Eytron width in micrometres

ML

Mandible length in micrometres
