Yucca moths are most well known for their obligate pollination mutualism with yuccas, where pollinator moths provide yuccas with pollen and, in exchange, the moth larvae feed on a subset of the developing yucca seeds. The pollinators, however, comprise only two of the three genera of yucca moths. Members of the third genus, Prodoxus, are the “bogus yucca moths” and are sister to the pollinator ...

Insect pest problems in forest nurseries of selected indigenous tree species viz., Calophyllum and Pterocarpus marsupium was studied at Peechi in Kerala State. The most serious pest incidence was noticed on G. arborea (by the caterpillars of Epiplema fulvilinea); A. odoratissima (by the Psyllid Psylla oblonga) and Pterocarpus marsupium [by the psyllids Spanioneura (quadrimaculata group) and Ary...

Herbivore species sharing a host plant often compete. In this study, we show that host plant-mediated interaction between two insect herbivores - a generalist and a specialist - results in a sex ratio shift of the specialist's offspring. We studied demographic parameters of the specialist Tupiocoris notatus (Hemiptera: Miridae) when co-infesting the host plant Nicotiana attenuata (Solanaceae) w...

Tea green leafhopper is one of the most damaging tea pests in main tea production regions of East Asia. For lack of recognized morphological characters, the dominant species of tea green leafhoppers in Mainland China, Taiwan and Japan have always been named as Empoasca vitis Göthe, Jacobiasca formosana Paoli and Empoasca onukii MATSUDA, respectively. Furthermore, nothing is known about the gene...

The microleafhopper genus Empoasca Walsh, 1862 from Bangladesh is revised herein. With the existing species E. vitis (Göthe, 1875), another three viz. kerri Singh-Pruthi, 1940, motti 1940 and onukii Matsuda, 1952 are described reported first time Bangladesh. Diagnostic descriptions, illustrations a key to provided. J. Zool. 51(1): 47-54, 2023

Background: Air pollution is a threat to the environment. Sources of air pollutants in urban environments can be form dust, heavy metals, and hydrocarbons. Plants help clean from atmosphere by absorption through stomata, accumulating them, or adsorption on leaf surface. The Pollution Tolerance Index (APTI) used as an evaluation benchmark for Physiological conditions plants exposed pollution. Th...

Since the early 2000s, reports on declining hornbeam trees (Carpinus betulus) are spreading in Europe. Two fungi involved decline phenomenon: One is Anthostoma decipiens, but other etiological agent has not been identified yet. We examined morphology, phylogenetic position, and pathogenicity of yellow fungal isolates obtained from Austria, Georgia Switzerland, compared data with disease norther...

Anisakiasis and Pseudoterranovosis are human diseases caused by the ingestion of live Anisakidae larvae in raw, undercooked or lightly marinated fish. Larvae were collected from one salted cod sold for human consumption in a Sao Paulo market in 2013. One section of one brownish larva was used for molecular analyses. The partial COX2 gene sequence from the larva had a nucleotide identity of 99.8...

One new diterpene ester with a tricyclic lathyrane-or myrsinol-type skeleton has been isolated fromEuphorbia decipiensBoiss. &Buhse. In addition to one new, the known constituents -amyrin, -amyrin acetate, methyl (2,4-dihydroxy-3-formyl-6-methoxy) phenyl ketone (2), and 1,1-bis (2,6-dihydroxy-3-acetyl-4-methoxyphenyl)methane (3) have been isolated from the same source. The structure elucidation...

Abstract Endosymbiotic bacteria can induce parthenogenesis in many haplo-diploid species, but little is known about their role asexual reproduction diplodiploids. Bacteria are essential for the lineages of springtails and booklice, possibly some weevils, whether they causative agent remains to be proven. This would require comparing unisexual forms closely related bisexual such model species ve...
