“…The varieties having high TSS were prone to be more susceptible when compared to less TSS. The results are in agreement with the findings of Sreedhar et al (2020) and they reported that higher per cent of sugars in groundnut varieties are preferred by bruchids. According to Deepika et al (2020), the infestation in stored chickpea varieties is more with increase in the total soluble sugars and vice versa.…”

“…Swamy et al (2020a) reported that the chickpea varieties showed a positive correlation with total soluble sugars against oviposition preference (r = 0.562), development of bruchid (r = 0.543) and grain damage (r = 0.534). Similarly, Pod sugars content of the groundnut varieties showed positive and significant relationship with number of eggs laid (r = 0.91), adult emergence (r = 0.90), per cent survival (r = 0.77), index of susceptibility (r = 0.86), while pod sugars content showed negative and nonsignificant relation with mean developmental period (r = 0.43) by Sreedhar et al (2020). Present results were also in agreement with Singh and Singh (2020) and Deepika et al (2020).…”

Background: Pulses constitute a cornerstone of the Indian diet, renowned for their rich protein content and nutritional benefits, frequently dubbed as the vegetarian’s protein powerhouse. Black gram not only provides nutritional benefits but also improves soil properties and fixes atmospheric nitrogen. If left unattended in storage, damage inflicted by three species of callosobruchus viz., C. chinensis, C. maculatus and C. analis on black gram seeds could result in substantial losses, both in quantity and quality. In the context of insect resistance, a host genotype’s ability to resist insect pests is demonstrated through non-preference, antibiosis, or tolerance, and is closely linked to the morphological, physiological and biochemical traits of the germplasm. The present study aims to pin point the specific biochemical properties of black gram seeds that contribute to their resistance against the pulse beetle. Methods: The experiment was conducted at the Department of Entomology and Agriculture Zoology, Institute of Agricultural Sciences, BHU, Varanasi during 2020-21. Bioassay investigations were undertaken on twelve varieties of black gram, evaluating various parameters including oviposition, adult emergence, mean development period, growth index, susceptibility index, and the biochemical constituents that could potentially impact the proliferation of the pulse beetle population. Result: The results revealed that tannins and phenols played a significant role in providing resistance. In contrast varieties with high sugars and proteins are susceptible to pulse beetle. However, an increase in the level of phenols and tannins in seeds may interfere with consumer acceptance and these aspects can be used in the breeding programme so as to develop host plant resistance against C. maculatus.

“…Thus, our second hypothesis, which projected that the spatial distribution of A. schrankie and its parasitoids would be negatively associated with phenol content, was supported, although positive associations between the densities of these insects and water and nitrogen content were not found. Only a few studies have demonstrated the negative effects of phenolic compounds (mostly tannins, a class of polyphenolic biomolecules) on the performance of seed-feeding insects, most of which are associated with bruchines, which are known pests (Oigiangbe and Onigbinde 1996; Regnault-Roger et al 2004; Tripathi et al 2013; Kaur et al 2016; Sreedhar et al 2020; Hamzavi et al 2022). Fewer studies have been conducted considering the third trophic level.…”

Many of the spatial patterns observed in nature are governed by interactions between species and between species and their environment, providing valuable information about which processes are determinants in shaping ecological communities. In a system composed of Mimosa bimucronata, the bruchine Acanthoscelides schrankie and its parasitoids, we examined the spatial distribution patterns of these insects and fruit quality. We tested the hypothesis that an aggregate pattern of parasitism is predominant, characterizing a direct density-dependent pattern. Because nitrogen, water, and phenols are crucial fruit traits that can affect the fitness of many insects, we also tested the hypothesis that the spatial distribution of A. schrankie and its parasitoids is positively associated with water and nitrogen content in the fruits and negatively associated (i.e., dissociation) with phenols. The distribution of bruchine and its parasitoids varied over time, from random to aggregated. The spatial patterns of parasitism varied between direct density dependence, inverse density dependence, and density independence. Dissociations were found between the abundance of A. schrankiae and the phenolic content, and similar results were found for the parasitoids. Our results suggest that a combination of bottom-up and top-down effects may drive spatiotemporal dynamics between A. schrankiae and its parasitoids. RÉSUMÉPlusieurs des patrons spatiaux observés dans la nature sont régis par des interactions entre les espéces et entre les espéces et l'environnement, ce qui fournit de l'information utile sur les processus importants dans la structuration des communautés écologiques. Dans un systéme composé de Mimosa bimucronata, de la bruche Acanthoscelides schrankie et de ses parasitoïdes, nous avons étudié les patrons de répartition spatiale des insectes et de la qualité des fruits. Nous avons testé l'hypothése de prédominance d'un patron agrégé de parasitisme indiquant une dépendance directe à la densité. Puisque l'azote, l'eau et les phénols sont d'importants traits des fruits qui peuvent influencer l'aptitude de plusieurs insectes, nous avons aussi testé l'hypothése selon laquelle la répartition de A. schrankie et de ses parasitoïdes est positivement associée au contenu en eau et en azote des fruits, et négativement associée (dissociation) au contenu en phénols. La répartition de la bruche et de ses parasitoïdes variait dans le temps, d'aléatoire à agrégée. Le patron spatial de parasitisme variait entre la dépendance directe à la densité, la dépendance inverse à la densité, et la non-dépendance à la densité. La dissociation a été observée entre l'abondance de A. schrankiae et de ses parasitoïdes et le contenu en phénols. Nos résultats suggérent qu'une combinaison d'effets ascendants et descendants pourrait expliquer la dynamique spatiale de A. schrankiae et de ses parasitoïdes.
