The occurrence of the leaf miner Asamangulia cuspidata Maulik (Coleoptera: Chrysomelidae: Cassidinae: Hispini) on sugarcane in Coimbatore, Tamil Nadu, India, is reported here with notes on pest biology and parasitoid activity. A minor pest in a few states of subtropical India, the miner was first noticed in May 2014 during routine surveys. Systematic observations in selected experimental and growers' plots revealed low levels of incidence and intensity, the highest mean attack rates being 4.18% on plant basis and 12.41% on leaf basis. Mean mined leaf area showed a high of 4.24 sq. cm and it constituted 1.28% of the total leaf area. Cross-sections of young and mature mines indicated feeding on softer tissues by the solitary grub in the early stages, but extensive mining by the grown-up grub leading to complete drying of the mined area. One apparently new Bracon sp. (Hymenoptera: Braconidae), two Pediobius spp. (Hymenoptera: Eulophidae) and one Eurytoma sp. (Hymenoptera: Eurytomidae) were recovered from the miner. While Bracon sp. contributed 70% to the overall parasitism rate of 39.3%, the remaining parasitoids accounted for 30% with likely hyperparasitism among them. The possible origin of the miner and the role of parasitoids in its natural control at the present study site are also discussed.Keywords

The Palghar district of Maharashtra falls in zone III of the seismic zoning map of India, where earthquakes up to magnitude 6.0 can occur1. A swarm activity was started in the Palghar district of Maharashtra in November 2018 and is still continuing (till the end of November 2019). According to reports from the National Centre for Seismology (NCS), more than 1,000 earthquakes of micro-tominor magnitude have occurred in the Dahanu and Talasari talukas of Palghar district, from 3 November 2018 to 15 February 2019. The biggest tremor of magnitude ML 3.7 was recorded on 1 February 2019, at 3.54 PM (IST). The people of Dahanu and Talasari talukas were panicked by the abnormal ground vibration and burst sound that they felt. In fact, Jawahar city in Palghar district has experienced swarms several times earlier.Full Text

Following the detection of an incongruity in the nomenclature of sugarcane web mite Schizotetranychus andropogoni (Hirst) (Acari: Tetranychidae), we collected web mite samples from commercial hybrids of sugarcane and Saccharum spontaneum in parts of Tamil Nadu and Kerala States, India. Acarologists identified these samples as Schizotetranychus krungthepensis Naing & Auger (Acari: Tetranychidae), originally described from Thailand in 2014. To provide molecular evidence to distinguish S. krungthepensis from S. andropogoni, we subjected sequences of 5.8S rRNA and mitochondrial cytochrome oxidase I (mtCOI) genes of both species available in NCBI database to Molecular Evolutionary Genetics Analysis (MEGA6). The analysis produced phylogenetic trees with distinct clusters for S. andropogoni and S. krungthepensis, albeit with some exceptions, thus providing evidence to consider S. krungthepensis a species distinctly different from S. andropogoni. In view of the possible threat of S. krungthepensis to sugarcane cultivation in the country, we outline the basic course of action needed to manage the pest if it were to assume more serious proportions than the native species it appears to be displacingFull Text
