“…Chemical cues are known to modulate various life-history processes and behavioural decisions, for instance, courtship (Arag on, 2009;Costanzo & Monteiro, 2007), mating (Billeter & Wolfner, 2018;Campos et al, 2017;Rodrigues et al, 2017), aggregations (Afrakhteh et al, 2020;Fouche et al, 2018), habitat selection (Buxton et al, 2020;Raitanen et al, 2014) and predation (Hermann & Thaler, 2014;Ninkovic et al, 2013) across taxa.…”

“…Survival from cannibalism under natural conditions is highly dependent on the organisms' abilities to detect and respond to various sources of information present in the environment, one of which is chemical cues (Crossland & Shine, 2011; Ferrer & Zimmer, 2007). Chemical cues are known to modulate various life‐history processes and behavioural decisions, for instance, courtship (Aragón, 2009; Costanzo & Monteiro, 2007), mating (Billeter & Wolfner, 2018; Campos et al, 2017; Rodrigues et al, 2017), aggregations (Afrakhteh et al, 2020; Fouche et al, 2018), habitat selection (Buxton et al, 2020; Raitanen et al, 2014) and predation (Hermann & Thaler, 2014; Ninkovic et al, 2013) across taxa.…”

1. Cannibalism and its role in population dynamics, along with various factors influencing the rate of cannibalism, have been widely studied across taxa.2. The effects of predatory cue concentrations and starvation on cannibalistic tendencies and other life-history traits in cannibalistic and non-cannibalistic adults of Menochilus sexmaculatus were investigated.3. Egg cannibalism increased with increasing predatory cue concentration and was maximum in high predatory cue treatment; increased with starvation irrespective of their diet history.4. Latency to cannibalise eggs was shorter for cannibalistic adults as compared to non-cannibalistic adults irrespective of their hunger status and concentration of conspecific cues. 5. Non-cannibalistic females have higher fecundity than cannibalistic females. 6. In conclusion, both cannibalistic and non-cannibalistic individuals respond differently to intrinsic (hunger) and extrinsic cues (predatory cue concentrations). Cannibalistic individuals cannibalise more than non-cannibalistic ones at low levels of starvation and predatory cues. 7. Our finding suggests that cannibalistic individuals are better at assessing the risk and removing future competitors, which might favour these individuals over noncannibalistic ones in adverse conditions and increased competition.

Crowding induces behavioral and lasting morphological and chromatic changes in insects. This study examined how larval rearing density of Propylea dissecta (Mulsant 1850) affected food choice and development duration, hypothesizing that larvae under stress will opt for lower quality food as larval density increases. Larvae were reared at various densities under three crowding treatments: direct physical, indirect physical, and chemical tracks. In each treatment, larvae experienced crowding at densities of 0, 2, 4, 6, 8, 10 and 12 individuals per arena. Fourth stage larvae were provided with food choice of aphids, heterospecific eggs and conspecific eggs. Significant effect of crowding on total development duration, first consumption time and first food consumption were observed. Decrease in development duration at densities of 4 and 6 and increase in development duration at low and high densities were observed in direct physical crowding. Indirect physical and chemical crowding yield the shortest development duration at densities of 8, 10, and 12, when compared to low and moderate crowding. First encounter time increased with increasing chemical tracks concentration, while first consumption time decreases with crowding across all groups. First consumed food was also significantly influenced by crowding, suggesting a negative impact on larval food choice. Our results indicate that crowding among larvae leads to a longer development duration and show less selectivity in their food choices.
