The first occurrence of an invasive pest species, the fall armyworm ( Lepidoptera: Noctuidae), in Bulgaria is reported. Different trapping methods (black light trap, traps baited with semiochemical lures, and food attractants) were used to study Noctuidae assemblages in Bulgaria in 2023. Two males of were caught with sex pheromone traps in maize fields in Knezha, northern Bulgaria, in early November 2023. Additionally, three moths were attracted by black light traps (early November 2023) and one moth by a food lure applied on a tree trunk at the end of October 2023 in the municipalities of Parvomay and Chirpan, southern Bulgaria, respectively. The identification of was confirmed using morphological and molecular methods.

Background: Silicon (Si) fertilization has been well-documented to enhance plant resistance against insect pests by increasing the abrasiveness and toughness of leaf tissues. Additionally, Si also interacts with the jasmonic acid pathway, which modulates antiherbivore induced defenses, including the emission of herbivore-induced plant volatiles (HIPVs) that attract natural enemies. In this study, we examined the influence of Si fertilization on the attractiveness of nocturnal HIPVs from maize plants infested with the fall armyworm (FAW), Spodoptera frugiperda (JE Smith), to the predatory earwig Doru luteipes (Scudder).

The ovary plays a crucial role in the female reproductive system of insects and is vital for the perpetuation of insect populations. The insulin/insulin-like growth factor signaling (IIS) and target of rapamycin (TOR) signaling network play a key role in controlling ovarian development and maturation during the adult stage. However, the pupal stage is a critical developmental phase in the reproductive system of holometabolous insects, and the regulatory role of the IIS/TOR network during this stage remains to be elucidated.

Mixed cropping systems typically provide better natural pest control compared with monocultures, although the success varies depending on the crop and cultivar combinations. Understanding trait interactions that confer associational resistance (AR) to companion plants is key to optimizing these benefits. The Mesoamerican milpa system, known for its pest resistance, provides a model for studying these interactions.

Rice (Oryza sativa L.), the staple food for half of the world's population, suffers heavy damage by insect herbivores, especially the emerging Fall Armyworm (FAW), Spodoptera frugiperda. HYR (HIGHER YIELD RICE), a master regulator of multiple biological pathways with an established gene regulatory network, has been found to improve rice yield to ~29% and tolerance to environmental stress.
