EXTERNAL MORPHOLOGY OF ANTENNAL SENSILLA IN RELATION TO ELECTROANTENNOGRAM RESPONSES OF Apanteles angaleti MUESEBACK PARASITOIDS (HYMENOPTERA: BRACONIDAE) FOR HOST SEARCHING BEHAVIOUR
The results indicated strongly the potential of semiochemical use as long and short range cues for modulating the host searching behavior of parasitoids in the tritrophic context and therefore aid in the formulation of insect pest management strategies for cotton ecosystems.

The Weevil Rostrum (Coleoptera: Curculionoidea): Internal Structure and Evolutionary Trends
- BiologyBulletin of the American Museum of Natural History
A comparative study was conducted of rostra throughout Curculionoidea to develop a more robust morphological character system for cladistic analysis of the higher lineages and to gain a comprehensive understanding of the structure of a hallmark feature of weevils.
Stiff upper lip: Labrum deformity and functionality in bees (Hymenoptera, Apoidea)
The labrum’s function in bees is discussed, as well as the implications of deformities to this and associated characteristics.
The ontogenetic saga of a social brain
The proposed molecular underpinnings of this phenomenon are variations in hormonal environments, which may mediate higher cell death rates in the queen’s brain than in the workers’, and an evolutionary by-product of the reproductive division of labour in species with female size diphenism.
Changes in follicular cells architecture during vitellogenin transport in the ovary of social Hymenoptera
Actin distribution in follicular cells during vitellogenin transport to the oocyte in social Hymenoptera represented by bees Apis mellifera and Melipona quadrifasciata, the wasp Mischocyttarus cassununga and the ant Pachycondyla curvinodis is described.
Description of antennal structures of the parasitoid Mallophora ruficauda (Diptera: Asilidae) and its relationship with resources searching behaviour
Considering the morphological characteristics of the antennae, and based on the olfaction biomechanics, the structure and distribution of these cuticular structures of the parasitoid antennae would contribute to the odour detection mechanism in adults of M. ruficauda.
Formation of the insect head involves lateral contribution of the intercalary segment, which depends on Tc-labial function.

Reinterpretations of clypeus and maxilla in Psocoptera, and their significance in phylogeny of Paraneoptera (Insecta: Neoptera)
Morphology of the head and mouthparts in Psocoptera was investigated, and revised interpretations for clypeus and maxilla were proposed, and brief discussions on the evolution of piercing and sucking mouthparts and on the phylogeny of Paraneoptera were provided.
