Feeding {BSagri}

Pupation and Hatching rate in a feeding experiment with four varieties

Description

Larvae of a non-target organism were fed with plant material derived from a novel variety(Novum), material from three standard varieties (NStandard: the standard variety most similar to Novum, and two additional standard varieties S1 and S2). Objective was to assess the impact of Novum on the pupation and hatching rate of an animal that potentially feeds on plant material compared to accepted standard varieties.

Usage

data(Feeding)

Format

A data frame with 32 observations on the following 5 variables.

Rep

a factor with 32 levels indexing the 32 replications

Variety

a factor with 4 levels: S1 and S2 are two standard varieties, Novum is a novel variety, and NStandard is the standard variety most similar to Novum

Total

the total number of animals in each experimental unit

Pupating

number of individuals pupating in each unit, the others died

Hatching

number of individuals hatching from the pupae

Examples

# Larval mortality:

Feeding$Lmort <- Feeding$Total - Feeding$Pupating

fit1<-glm(cbind(Pupating,Lmort)~Variety,data=Feeding, family=quasibinomial)
