“…The H. armigera colony was established and kept at the Laboratório de Resistência de Plantas a Insetos e Plantas Inseticidas (LARESPI) of the Department of Plant Protection for eight generations (Silva et al ., 2018). The larvae and adults used in the experiments were from the mass rearing fed on artificial diet maintained, to avoid larval preconditioning (Petit et al ., 2018).

Helicoverpa armigera is a pest of several crops causing significant economic impact. We evaluated the insect development on different vegetative and reproductive structures of cotton, maize, and soybean compared to artificial diet. One hundred individuals were evaluated per structure (cotton leaves and bolls; maize leaves, grains, and silk; soybean leaves and pods) and artificial diet. Centesimal analyses were performed on quantifiable nutrient contents in diets. The viability of immatures (eggs, larvae, and pupae) ranged from 30% on maize leaf to 74% on cotton bolls, while on the artificial diet, it was 70%. Maize, cotton, and soybean leaves provided viability of 30, 37, and 42%, respectively, revealing these leaves tissues are less favorable to the development of H. armigera immatures compared to ‘reproductive tissues’. Centesimal composition of diets compared 14 common components in all diets, which correlated significantly with larval and pupal stages and/or pupal weight. Of the 12 dietary components that significantly affected larval development time, half were negatively correlated, indicating a decrease in developmental time from their increments. In general, when insects were confined separately to substrates, the artificial diet was the most suitable for H. armigera development compared to the evaluated natural diets. However, in natural conditions, the variability of available hosts must be considered. In addition, it is acceptable for moths to select more suitable hosts for oviposition, while their larvae move to other more suitable tissues of the same plant or even migrate to other plants.

“…3 For example, the induction of preference of the polyphagous Sesamia nonagrioides for a new olfactory cue, vanillin in third-instar larvae was determined by parents' and self-experiences. 1 Also, both naïve and experienced (fed on poplar) Lymantria dispar caterpillars adapt to the same volatiles, (Z)-3-hexenyl acetate, but especially (E)-4,8-dimethyl-1,3,7-nonatriene to experienced caterpillars. 15 Furthermore, the third-and fourth-instar larvae of the polyphagous Spodoptera litura which switched from castor to eggplants showed improved fitness and shortened generation time, indicating that the larvae possess the ability to know best, which may be one of the traits underlying the exceptional adaptability of the species.…”

“…Polyphagous species exhibit higher behavioral plasticity than oligo‐ and monophagous species, 1 which largely depend on the larval ability to identify the best host by memorizing plant olfactory cues associated with food resources 2,3 . The quality and quantity of plant volatiles change with the growth of larvae 4 .…”

“…15 Other lepidopteran stem borers can also acquire preferences for new olfactory cues from the larval to the adult stage. 1 Previous studies have showed that olfactory proteins, for example the odorant receptor (OR) , EcorOR25 in Eupeodes corollae, are involved in the detection of aromatic volatiles, such as eugenol and methyl eugenol, 16 and GmolOR12 in Grapholita molesta plays an important role in sensing host-plant volatile aldehydes. 17 Similarly, olfactory proteins in the polyphagous E. signifer may be involved in the sensing of host volatile organic compounds by the third-instar larvae, which is a typical example of native pest adaptation to introduced trees.…”

BACKGROUND Endoclita signifer is a polyphagous lepidopteran species of eucalyptus that selects its hosts in the third‐instar larval period. To understand how it adapts to its host during development, we studied the olfactory responses of late‐stage (fifth)‐instar larvae to the dynamic chemical environment they encounter. RESULTS Thirty‐two volatiles from eucalyptus trunk and soil were identified, among which 14 showed electroantennal activity and five were identified as new. Further behavioral bioassay showed that both β‐pinene and the imitation ratio of six key volatile in eucalyptus trunk were attractive to the fifth‐instar larvae, but both eliminated and increased β‐pinene in the mixture decreased the choice ratio and showed no attraction. Although E. signifer larvae shifted their attraction from o‐cymene at the third‐instar stage to β‐pinene at the fifth‐instar stage in a single volatile, the appropriate ratio of the main compounds in eucalyptus trunk volatile is the key to the behavior choice of fifth‐instar larvae. CONCLUSION The switch in olfactory attraction to different compounds between fifth‐ and third‐instar larvae indicated an olfactory plasticity between third‐ and fifth‐instar larvae. And the particular blend mediated the highly specialized communication interactions specificity between fifth‐instar larvae and eucalyptus trunk volatile indicated the specialized host adaptation to fifth‐instar larvae. This enhances understanding of how the primitive lepidopteran E. signifier, as a native pest, adapts to introduced eucalyptus. Moreover, this study provides knowledge for the screening and development of target volatiles for trapping and managing E. signifer larvae. © 2022 Society of Chemical Industry.

“…These plant attributes are used by foraging insects to assess the suitability of a plant and leads to the development of preferences for host plants by insect species [23,24]. Busseola fusca moths and larvae possess sensory structures able to detect plant compounds that influence host plant choice [25,26]. It is therefore possible that the presence of Bt-toxins in maize leaf tissue can be detected by foraging larvae and that this may affect their feeding and migration behaviour.…”

Busseola fusca (Fuller) (Lepidoptera: Noctuidae) is a destructive pest of maize throughout the African continent. Bt maize is an effective control measure for this pest, however, selection pressure for resistance evolution is high. This necessitates the implementation of insect resistance management (IRM) strategies such as the high-dose/refuge strategy. This IRM strategy relies on the validity of several assumptions about the behaviour of pests during insect-hostplant interactions. In this study, the migration behaviour of B. fusca larvae was evaluated in a semi-field (greenhouse) and field setting. The effect of factors such as different Cry proteins, plant growth stage at infestation, and plant density on the rate and distance of larval migration were investigated over four and five week periods. Migration of the larvae were recorded by using both a leaf feeding damage rating scale and destructive sampling at the end of the trials. Results indicated that B. fusca larval migration success was significantly affected by plant growth stage and plant density—while limited larval migration was recorded in plots inoculated with larvae at a late growth stage (V10), higher plant density facilitated increased interplant migration. The results also suggest that B. fusca larvae do not migrate extensively (rarely further than two plants from the natal plant) and that larval mortality is high. Implications for IRM strategies are discussed.
