This article summarizes the knowledge to date on biology of the potato leafhopper, Empoasca fabae (Harris), including its distribution, development, migration, agricultural host plants, and mechanics of injury to host plants. Damage to alfalfa, potatoes, soybeans, and snap beans, and treatment guidelines, are summarized. Particular attention is given to integrated pest management options in alf...

A novel iflavirus was discovered from the transcriptome of the leafhopper Graminella nigrifrons. The assembled virus genome has 9,700 nucleotides (nt) and encodes a 3,035-amino-acid polyprotein. Sanger sequencing was used to confirm the sequence encoding the polyprotein and indicated a genome length of 9,617 nt with a polyadenylated tail.

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

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...
