Arthropods That Stress Waterhyacinth

Abstract: More than 70 species of arthropods were found to feed on waterhyacinth, Eichhornia crassipes (Mart.) Solms, in South America, the United States, and India. Those that were destructive were divided into categories based on the type of damage produced, that is, (1) defoliators and external leaf feeders, represented by Cornops spp. (Orthoptera: Acrididae), and adult Neochetina spp. (Coleoptera: Curculionidae); (2) petiole borers, represented by Acigona infusella (Walker) and Epipagis albiguttalis (Warren) (Lepidoptera: Pyralidae), Arzama densa Walker (Lepidoptera: Noctuidae), and larval Neochetina spp.; (3) leaf tunnel producers, represented by Orthogalumna terebrantis Wallwork (Acarina: Galumnidae); and (4) scavenger species such as Dyscinetus spp. (Coleoptera: Scarabaeidae), which enhance the effect of attack by other insects. This damage is also often amplified by pathogens and other less abundant arthropods.

X-tox: An atypical defensin derived family of immune-related proteins specific to Lepidoptera

Abstract: We report here the isolation in Spodoptera frugiperda (Lepidoptera) of an immune-related protein (hereafter named Spod-11-tox), characterized by imperfectly conserved tandem repeats of 11 cysteine-stabilized alpha beta motifs (CS-αβ), the structural scaffold characteristic of invertebrate defensins and scorpion toxins Spod-11-tox orthologs were only found in Lepidopteran species, suggesting that this new protein family (named X-tox) is specific to this insect order Moreover, phylogenetic analysis suggests that X-tox proteins represent a new class of proteins restricted to Lepidoptera and likely derived from Lepidopteran defensins In S frugiperda, analysis of gene expression revealed that spod-11-tox is rapidly induced by infection However, and conversely to what is known for most insect antimicrobial peptides (AMP), spod-11-tox is mainly expressed in blood cells Moreover, recombinant Spod-11-tox produced in the Sf9 cell line does not show any antimicrobial activity Altogether, these results suggest that although X-tox proteins are derived from defensins, they may play a different and still unknown role in Lepidoptera immune response

Studies on dipterous parasites of the spruce budworm, choristoneura fumiferana (clem.) (lepidoptera: tortricidae): vii. agria affinis (fall.) (diptera : sarcophagidae)

Abstract: Agria affinis (Fall.), a holarctic parasite of Lepidoptera, Orthoptera, and Hymenoptera and one of the more common of the native sarcophagid parasites of Choristoneura fumiferana (Clem.) in British...
