Appetitive and aversive learning in Spodoptera littoralis larvae.
Adult Lepidoptera are capable of associative learning. This helps them to forage flowers or to find suitable oviposition sites. Larval learning has never been seriously considered because they have limited foraging capabilities and usually depend on adults as concerns their food choices. We tested if Spodoptera littoralis larvae can learn to associate an odor with a tastant using a new classica...
متن کاملAppetitive and Aversive Learning in Spodoptera littoralis Larvae
Page 725 Adult butterflies are capable of associative learning that serves foraging flowers or finding oviposition sites. In experimental paradigms, they learn to extend their proboscis in response to floral orders associated with a sugar reward or to avoid them if paired with bitter substances. Such settings have been used to elucidate the neuronal circuitry and mechanisms underlying the afore...
متن کاملField Persistence of Some Novel Insecticides Residues on Cotton Plants and Their Latent Effects against Spodoptera littoralis (Boisduval)
New insecticides that exhibited high compatibility with environment components are very promising substitutes for control of the economic insects. Simi-field experiments were conducted on profenofos and four novel insecticides viz., spinosad, emamectin-benzoate, pyridalyl and indoxacarb to investigate their efficiency and the field persistence of their residues against 4 instar larvae of the co...
متن کاملPossible bases of pseudoparasitism in Spodoptera littoralis larvae stung by Microplitis rufiventris.
The effects of host age and parasitoid female age on the occurrence of 'Pseudoparasitism', using the Spodoptera littoralis-Microplitis rufiventris host-parasitoid system were investigated. The first four larval instars of the host are not equally suitable for parasitoid development. The proportion of pseudoparasitized hosts significantly increases when: (1) the age of the female parasitoid incr...
متن کاملShort communication. The antifeedant activity of natural plant products towards the larvae of Spodoptera littoralis
Worms are becoming difficult pests to control since many insecticides are now forbidden and the present alternatives are insufficiently effective. Antifeedants of plant origin may have potential against such pests. In this work, several diterpenoids, flavones and coumarins extracted from plants were assayed as antifeedant agents against Spodoptera littoralis larvae. Among these compounds, four ...
