F I G U R E 2 in Female-female aggression in Bactrocera tryoni (Diptera: Tephritidae) and the influence of fruit quality on combat intensity
F I G U R E 2 Mean (±SE) time (in seconds) taken for a female Bactrocera tryoni to perform the first antagonistic behavioural event against a conspecific female when on one of three host fruit types. N = 15 female pairs per fruit type. Columns surmounted by different letters are significantly different at p = 0.05.
F I G U R E 3 in Oviposition by the oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), on five citrus types in a laboratory
F I G U R E 3 Mean (±1 SE) proportion of time female Bactrocera dorsalis spent on aggression, grooming, oviposition, probing, being inactive, and walking and tasting on (a) damaged and (b) undamaged citrus types and a positive control (Golden Delicious apple). Citrus types investigated were Golden Delicious apple, Delta Valencia orange, Eureka lemon, Glen Ora navel orange, Nadorcott mandarin and Star Ruby grapefruit. Each female was observed for 20 min.
F I G U R E 2 in Oviposition by the oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), on five citrus types in a laboratory
F I G U R E 2 First-order Markovian analyses showing the probability of transition from one behaviour to another by gravid female Bactrocera dorsalis on (a) damaged and (b) undamaged citrus (all types pooled). Transitions with p ≥ 0.10 are indicated by solid lines, and those with 0.09 ≥ p ≥ 0.03 are indicated by dashed lines. Values in parentheses indicate frequencies of each behaviour observed.
F I G U R E 1 in Female-female aggression in Bactrocera tryoni (Diptera: Tephritidae) and the influence of fruit quality on combat intensity
F I G U R E 1 Ethogram of antagonistic behaviours of female Bactrocera tryoni competing for a single host fruit. The size of the behavioural boxes and number within represent the frequency in which the individual behaviours occurred that led to a transitional flow to another behaviour. The number associated with the arrow represents the proportion of transition frequencies made by the females to other behaviours from a given behaviour and will sum to 1. For example, from a total number of observed behavioural events recorded for crabbing, a proportion of 0.381 of all transitions led to further crabbing (after the first crabbing had finished), 0.237 led to supination, 0.130 led to pushing, 0.091 led to tiptoe, 0.083 led to probing, 0.033 led to butting, 0.032 led to retreat and 0.014 led to chasing. The ethogram is based on 45 replicate recordings, each 1 h long of two sexually mature females competing for access to a single fruit resource for oviposition. The ethogram thus represents the combined behaviours of 90 individuals.
F I G U R E 4 in Female-female aggression in Bactrocera tryoni (Diptera: Tephritidae) and the influence of fruit quality on combat intensity
F I G U R E 4 Mean (±1 SE) number of occurrences of aggressive behaviours exhibited by Bactrocera tryoni females on three fruit types: cherry tomato, apple and mango. N = 15 replicate female–female pairs per fruit type. Columns surmounted by different letters are significantly different at p = 0.05.
