Research paper thumbnail of Note on Occurrence of Areca White Grub (Coleoptera, Scarabaeidae, Melolonthinae, Leucopholini) from Northern Western Ghats and its Implications

We report the first ever distribution record of an Areca white grub, Leucopholis burmeisteri Brenske, 1894 from the Northern Western Ghats, Maharashtra, India. It is an economically important pest reported to be damaging the cash crops viz., sugarcane, coconut, Areca nut and several other vegetables. In this study the species was re-described with illustration of female specimens. The identity of the species was reconfirmed using DNA barcoding by sequencing the 5’ region of mitochondrial cytochrome oxidase subunit I (mtCOI-5P). The evolutionary history inferred by constructing a phylogenetic tree using Maximum Likelihood method based on the General Time Reversible model showed that L. burmeisteri formed clustered with L. burmeisteri reported from Karnataka thus reconfirming, by molecular means, the ...

The present study was designed to carry out periodic diversity assessments to understand the trends in diversity patterns of hawk moths. The study was carried out in the northern Western Ghats in Nashik district. Seven sampling stations were identified and periodic visits to these places were carried out over the span of five years (2011–2015). A total of 463 moths were recorded belonging to 18 species, represented by 10 genera. A new record from Western Ghat, Theretra sumatrensis (Joicey & Kaye 1917) is reported for the first time along with its DNA barcode. Six diversity indices (four alpha diversity indices and two beta diversity indices) were employed to understand the diversity dynamics. Whittaker’s plot was generated using the rank abundance suggesting high species evenness for all sampling stations. Maximum diversity was ob...

These were further authenticated by ZSI, Pune, Maharashtra, India. These documented coleopterans were placed in 14 genera,06 subfamilies and 03 families viz. Scarabaeidae, Geotrupidae and Hybosoridae . Dung beetles were collected using dung baited pitfall traps, light traps and handpicking at five regions belonging to different localities within the study area. Scarabaeinae and Rutelidae were the dominant subfamily belonging to our collection.

Their activity were compared with synthetic napthaquinones, menadione, two benzoquinones, 2,6‐dimethyl and 2,3,6‐trimethylbenzoquinone and a hydroquinone 2,6‐dimethylhydroquinone. As far as the authors are aware, the present investigation is the first systematic attempt to investigate the effects of quinones on different aspects of reproduction, namely mating behaviour, fecundity and fertility. All the above types of quinones have revealed adverse effects on the reproduction of D. koenigii, which were topically treated as 1‐day‐old adults with different doses of the compounds depending on their 50% lethality (LD50) values. Analysis of the data revealed a highly statistically significant reduction in the number of eggs, their hatching and further development up to the final instar stage. The s...

Journal of Threatened Taxa

These conspicuous, attractive, and tiny leaf chafers are recorded as predators of several agricultural crops. The mt DNA Barcodes of many Adoretus Dejean, 1833 species are available in global databases. In this work, first DNA barcode of A. kanarensis has been reported. Morphological details with photographs of the species along with a checklist of the genus Adoretus from Maharashtra is provided. The mt COI DNA sequences of Adoretus species recorded until now for the genus that are listed in GenBank are analyzed.

Dang District is identified as a hot spot for megadiversity of butterflies. Wings of all the three families Papilionidae, Nymphalidae and Pieridae showed considerable variations in shapes and vein patterns reflecting their specific nature. An interesting observation was done in Delias eucharias belonging to the family Pieridae. This butterfly showed two veins missing, namely second radial R2 and first cubitus Cu1 from forewing.

These includes vast array of chemicals like phenols alkaloids, quinines, etc. Quinones are heterocyclic compounds consisting of prototypical member of the class includes 1,4-benzoquinone or cyclohexadienedione, 1,2-benzoquinone (ortho-quinone), 1,4naphthoquinone(para-quinone) and 9,10-anthraquinone. 1,4-benzoquinone or cyclohexadienedione is often called quinone and are found to either stimulate or inhibit the feeding in insects. Of these, tetrahydroxy-1,4benzoquinone, also called tetrahydroxy-p-benzoquinone, was tested for its effects on growth and metamorphosis of Spodoptera litura larva. Fifth instar larvae were topically treated with various concentrations of acetone solutions of tetrahydroxy -p-benzoquinone to test the efficacy of the compound. It was interesting to note that the treated group showed reduced relative feeding. Also interference in moulting process, ecdysial failure and blockage of normal adult eme...
