Physopelta schlanbuschii, a phytosuccivorous bug fed mainly on Trivea nudiflora bark and seeds and provided fat, carbohydrate and some amount of protein to the bug. Besides this, bug population feeds on other host plants to meet the demand of water, minerals and amino acids. Food preference studies revealed that among a good number of food plants, it had preferential feeding on T. nudiflora. Different instars and adult oriented towards food source differently. During orientation towards food…

Ovipositional and Orientational Behaviour of Helicoverpa armigera (Hüb) on Selected Tomato Accessions
TLDR
The result on preference for oviposition under free choice test indicated that the resistant accession LE 228 had recorded the lowest number of eggs on upper leaf surface, lower leaf surface and on stem while susceptibleAccession LE 4 which was the most preferred one supported comparatively more numbers of eggs.
Morphological Disparity of the Mouthparts in Polyphagous Species of Largidae (Heteroptera: Pentatomomorpha: Pyrrhocoroidea) Reveals Feeding Specialization
TLDR
Based on structural differences, it is inferred that the mandibles and maxillae are more adapted for seed-sucking in Physopelta species than in M. grandis, which has the ends of themaxillae more narrowed, a trait more adapted to sucking sap from phloem or parenchymal cells.
Comparative phylogenetic analysis of bacterial associates in Pyrrhocoroidea and evidence for ancient and persistent environmental symbiont reacquisition in Largidae (Hemiptera: Heteroptera)
TLDR
Understanding of the evolution of symbiotic complexes in Hemiptera is contributed by characterizing bacterial associates of Pyrrhocoroidea focusing on the family Largidae and by constructing a phylogeny to establish evolutionary relationships of and within this group.
Phylogenetic Evidence for Ancient and Persistent Environmental Symbiont Reacquisition in Largidae (Hemiptera: Heteroptera)
TLDR
Evidence suggests that species of Largidae reacquire specific symbiotic bacteria from the environment every generation, which is a rare strategy for insects, with potentially volatile evolutionary ramifications, but one that must have persisted in Larg families and related lineages since their origin in the Cretaceous Period.
