Effect of a Marking Pheromone and Population Density on Ladybird Larval Development and Adult Body Mass [PDF]
Females of predaceous ladybirds use sensing chemicals in larval tracks as an oviposition-deterring pheromone to avoid cannibalism of eggs. We hypothesized that larvae would also respond to the presence of conspecific tracks by slowing their developmental

Larval habitat preferences of Anopheles dirus and Anopheles maculatus in North Sumatra, Indonesia [PDF]
Background While human malaria transmission in Indonesia has declined, reported cases of zoonotic Plasmodium knowlesi are increasing. This study examined the larval habitats of malaria vectors in North Sumatra to assess the potential of larval source ...

Response of chrysopids (Neuroptera) to larval tracks of aphidophagous coccinellids (Coleoptera)
Choice tests showed that tracks left by coccinellid larvae have generally little effect on oviposition site selection by chrysopid females. Fresh tracks of first instar larvae of the coccinellid species Coccinella septempunctata, Cycloneda limbifer, Leis

We investigated the ability of females of the aphidophagous chrysopids Chrysopa oculata and Chrysopa perla to distinguish clean substrates from substrates with tracks of chrysopid first instars after ablation of various sensory organs potentially ...
