Variable descriptions:

Plot: ID number for the individual cage.

Block: plots were separated into three blocks per round. Blocks were planted and counted within the same week, but on separate days.

Treatment: Plant treatment:
      M82 Mono: Commercial genotype monoculture.
      10_3 Mono: Altered terpenes monoculture.
      1_3 Mono: Altered acyl sugars monoculture.
      M82 + 10_3: Commercial and altered terpenes biculture.
      M82 + 1_3: Commercial and altered acyl sugars biculture.
      1_3+10_3: Altered terpenes and altered acyl sugars biculture.
Poly = polyculture. One plant of each genotype (commercial, altered terpenes, altered acyl sugars).

Date: date data was recorded.

alive_1, alive_2, alive_3: number of T. ni found alive on plants 1, 2, and 3, respectively.

dead_1, dead_2, dead_3: number of T. ni found dead on plants 1, 2, and 3, respectively.

Podi_1, Podi_2, Podi_3: number of P. maculiventris found on plants 1, 2, and 3, respectively.

notes_1, notes_2, notes_3: any additional information to record for plants 1, 2, and 3, respectively.

Total_cat: the total number of living T. ni caterpillars found in a cage.

Round: round 1 or 2 of the experiment; June-July (Round 1) or Aug-Sept (Round 2)

Census: 2 censuses were performed for each round as well as one final harvest.

Gen_1, Gen_2, Gen_3: genotype of plants 1, 2, and 3, respectively.

num_leaves_1, num_leaves_2, num_leaves_3: total number of compound leaves per plant
dmg_leaves_1, dmg_leaves_2, dmg_leaves_3: total number of compound leaves per plant with herbivory damage

dmg_sev_1, dmg_sev_2, dmg_sev_3: damage severity rating; a qualitative measurement on a scale from 0-10, with 1 = 1-10% plant area damaged, 2 = 11-20% plant area damaged, etc.

insects_1, insects_2, insects_3: insects found on plants 1, 2, and 3.

Pred?: Predators present in cage (P) or not present (NP).
