“…P. flammans adults are active during the photophase that lasts from 6:00 to 16:00 h and mate from 9:00 to 19:00 h [32,43]. Although different management strategies have been explored to control P. flammans [46,47], chemical control is still one of the main management techniques. However, the overuse of insecticides could result in insect resistance to the most commonly used products as well as environmental contamination [48].…”

Sex pheromone-binding proteins (PBPs) play an important role in sex pheromone recognition in Lepidoptera. However, the mechanisms of chemical communication mediating the response to sex pheromones remain unclear in the diurnal moths of the superfamily Zygaenoidea. In this study, Phauda flammans (Walker) (Lepidoptera: Zygaenoidea: Phaudidae) was used as a model insect to explore the molecular mechanism of sex pheromone perception in the superfamily Zygaenoidea. Two novel pheromone-binding proteins (PflaPBP1 and PflaPBP2) from P. flammans were identified. The two pheromone-binding proteins were predominantly expressed in the antennae of P. flammans male and female moths, in which PflaPBP1 had stronger binding affinity to the female sex pheromones Z-9-hexadecenal and (Z, Z, Z)-9, 12, 15-octadecatrienal, PflaPBP2 had stronger binding affinity only for (Z, Z, Z)-9, 12, 15-octadecatrienal, and no apparent binding affinity to Z-9-hexadecenal. The molecular docking results indicated that Ile 170 and Leu 169 are predicted to be important in the binding of the sex pheromone to PflaPBP1 and PflaPBP2. We concluded that PflaPBP1 and PflaPBP2 may be responsible for the recognition of two sex pheromone components and may function differently in female and male P. flammans. These results provide a foundation for the development of pest control by exploring sex pheromone blocking agents and the application of sex pheromones and their analogs for insect pests in the superfamily Zygaenoidea.

“…The pupae were kept in separate plastic containers (16 cm × 10 cm) closed with perforated plastic lids until adult emergence for species identification. In case of parasitism, the emerged parasitoids were conserved in 70% ethanol in glass vials (2.5 cm in diameter and 7.5 cm high) for species morphological identification [35][36][37] in collaboration with the Biosystematics Unit of International Centre of Insect Physiology and Ecology (icipe).…”

The interactions among insect communities influence the composition of pest complexes that attack crops and, in parallel, their natural enemies, which regulate their abundance. The lepidopteran stemborers have been the major maize pests in Kenya. Their population has been regulated by natural enemies, mostly parasitoids, some of which have been used for biological control. It is not known how a new exotic invasive species, such as the fall armyworm (FAW), Spodoptera frugiperda (Lepidoptera, Noctuidae), may affect the abundance and parasitism of the resident stemborers. For this reason, pest and parasitism surveys have been conducted, before and after the FAW invaded Kenya, in maize fields in 40 localities across 6 agroecological zones (AEZs) during the maize-growing season, as well as at 3 different plant growth stages (pre-tasseling, reproductive, and senescence stages) in 2 elevations at mid-altitude, where all maize stemborer species used to occur together. Results indicated that the introduction of the FAW significantly correlated with the reduction of the abundance of the resident communities of maize stemborers and parasitoids in maize fields; moreover, the decrease of stemborer density after the arrival of FAW occurred mostly at both reproductive and senescent maize stages. It also suggests a possible displacement of stemborers by FAW elsewhere; for example, to other cereals. However, since this study was conducted only three years after the introduction of the FAW, further studies will need to be conducted to confirm such displacements.

BACKGROUND: Phauda flammans Walker is a notorious defoliating pest of Ficus spp. in Southeast Asian. Sex pheromones have been identified as an effective method of biological control. However, little is known about the sex pheromone communication of P. flammans due to a lack of knowledge regarding the diel rhythms of sexual behavior and a lack of field tests using sex pheromone attractants. :00 h. The attraction of virgin males to P. flammans females suggested the utilization of sex pheromones. We identified Z-9-hexadecenal and (Z,Z,Z)-9,12,15-octadecatrienal as the primary components and found that they elicited the largest electroantennographic detection responses from the antennae of males. Field tests confirmed that P. flammans males can be captured by the two synthetic pheromone components at a ratio of 1:1. The capture of only males in field tests using the synthetic compounds confirmed the activity of the identified sex pheromone candidates. CONCLUSION:The results provide useful information for the design of standardized sex pheromone traps for the monitoring as well as trapping of P. flammans in the field.
