“…No-choice oviposition preference study revealed that T. tomentosa most preferred host for A. mylitta for oviposition. The leaves of T. tomentosa are physiological (leaf moisture content and net photosynthesis rate) and biochemical (Chlorophyll, protein, carbohydrate and crude fibre contents) superior over the other host plants in terms of nutritional status for growth and Redox active metals (iron and copper) and selenium were also high in S. robusta compared T. tomentosa and T. arjuna and deteriorate the nutritional quality of food plants by oxidization (Sahu et al, 2018).…”

“…Similarly, T. tomentosa also posessed highest percentage of moisture, chlorophyll and proteins than T. arjuna, whereas relatively higher percentage of sugar and phenol in the leaves of T. arjuna (Mukherjee et al, 2016;Deshmukh et al, 2019). Total flavonoid and tannin contents were much higher in the leaves of T. tomentosa and S. robusta, respectively (Sahu et al, 2018). Rath et al (2008) reported that the performance of A. mylitta on T. tomentosa superior than T. arjuna and Z. jujuba, in terms of fecundity and commercial characters.…”

Aim: Seed production is the backbone of sericulture in India. In order to cater for the increased demand for seed (egg), the already prevailing seed production techniques need to replace with new and robust techniques. Therefore, the present study was designed to understand the oviposition preference of Antheraea mylitta and selected suitable host plants for future improvement of seed production. Methodology: Choice (nylon net cage) and no-choice (earthen cup) experiments were conducted to study the oviposition preference of A. mylitta on Shorea robusta, Terminalia tomentosa, T. arjuna, Ziziphus mauritiana, Careya arborea, Syzygium cumini and Buchanania lanzan. Mated female moths were released freely into the nylon cage to observe their oviposition preference in the choice test. Whereas, half of both fore wings and hind wings of mated female moths were excised and individually placed in an earthen cup for oviposition. The total number of eggs laid on the host plants in both experiments was recorded and analysed. Results: Mated females released freely within the cage have laid the majority of their eggs on the floor and net instead of their host plants. Among the host plants, the highest number of oviposition was recorded on the S. robusta, T. tomentosa and T. arjuna compared to other host plants. The highest number of eggs per moth was observed on T. tomentosa and followed by S. robusta, T. arjuna and Z. mauritiana, and exceeded the numbers of eggs in the control in the no-choice experiment. Interpretation: The study revealed that both S. robusta and T. tomentosa were highly preferred host plants of A. mylitta for oviposition. Therefore, the volatiles or feeding supplements of S. robusta and T. tomentosa may be identified and applied to A. mylitta during rearing and grainage to enhance seed production. Key words: Host plants, Oviposition preference, Sericulture, Tasar silkworm, Terminalia tomentosa

Plant–soil interactions have bottom–up and top–down effects within a plant community. Heavy metal pollution can change plant–soil interactions, directly influence bottom–up effects and indirectly affect herbivores within the community. In turn, herbivores can affect plant–soil interactions through top–down effects. However, the combined effects of heavy metals and herbivores on soil enzymes, plants and herbivores have rarely been reported. Therefore, the effects of lead (Pb), Spodoptera litura and their combined effects on soil enzyme activities, pakchoi nutrition, defence compounds and S. litura fitness were examined here. Results showed that Pb, S. litura and their combined effects significantly affected soil enzymes, pakchoi and S. litura. Specifically, exposure to double stress (Pb and S. litura) decreased soil urease, phosphatase and sucrase activities compared with controls. Furthermore, the soluble protein and sugar contents of pakchoi decreased, and the trypsin inhibitor content and antioxidant enzyme activity increased. Finally, the S. litura development period was extended, and survival, emergence rates and body weight decreased after exposure to double stress. The combined stress of Pb and S. litura significantly decreased soil enzyme activities. Heavy metal accumulation in plants may create a superposition or synergistic effect with heavy metal-mediated plant chemical defence, further suppressing herbivore development. Pb, S. litura and their combined effects inhibited soil enzyme activities, improved pakchoi resistance and reduced S. litura development. The results reveal details of soil–plant–herbivore interactions and provide a reference for crop pest control management in the presence of heavy metal pollution.
