BIOLOGY OF THE MEALYBUG, PLANOCOCCUS CAJANI MUKHERJEE & MUKHOPADHYAY (PSEUDOCOCCIDAE : HOMOPTERA)
No full textBiology of mealybug, Planococcus cajani Mukherjee & Mukhopadhyay has been worked out. Mode of reproduction of the insect is sexual and oviparous. The female and male nymphs moult thrice and four times, respectively in 16-21 (18.41 ± 1.70) days and 13-19 (16.26 ± 2.0) days at 28.1-29.9°C and 84-93% R.H. to attain their adulthood. The male : female ratio is 1 : 1.30. The pre-oviposition and oviposition period, fecundity and incubation period of eggs are : 2-5 (3.4 ± 1.35) days, 3-7 (4.6 ± 1.49) days, 54-225 (163.16 ± 57.86) eggs/female and 4.5-6.0 (5.2 ± 5.0) days, respectively
Exploring new features for the (2+1)-dimensional Kundu-Mukherjee-Naskar equation via the techniques of (G'/G, 1/G)-expansion and exponential rational function
No full textThe aim of the manuscript is to study new optical soliton solutions of the Kundu–Mukherjee–Naskar (KMN) equation via the (G′/ G, 1 / G )-expansion technique and the exponential rational function (ERF) procedure. The results are produced under the constraint conditions, and their graphical representation highlights them. These discoveries might aid in the comprehension of intricate nonlinear phenomena and oceanography. Studying the investigated equation in this paper is very important in explaining oceanographic phenomena such as rogue waves’ ocean currents

The Optical Solutions of the Stochastic Fractional Kundu–Mukherjee–Naskar Model by Two Different Methods
No full textIn this paper, we focus on the stochastic fractional Kundu–Mukherjee–Naskar equation perturbed in the Stratonovich sense by the multiplicative Wiener process. To gain new elliptic, rational, hyperbolic and trigonometric stochastic solutions, we use two different methods: the Jacobi elliptic function method and the (G′/G)-expansion method. Because of the significance of the Kundu-Mukherjee equation in a magnetized plasma, the obtained solutions are useful in understanding many remarkable physical phenomena. Furthermore, we show the effect of the multiplicative Wiener process on the obtained solutions of the Kundu–Mukherjee–Naskar equation

Holotype male, labelled ‘ Holotype Demicryptochironomus (Irmakia) dividuus sp. n., India, West Bengal, Darjeeling [26.7095° N, 88.3542° E], 04.ix.2021, Coll. G. Pal’. Paratype 1 male, labelled ‘ Paratype Demicryptochironomus (Irmakia) dividuus sp. n., India, West Bengal, Burdwan [23.2393° N, 87.8512° E], 26.ii.2021, Coll. N. Hazra’. Diagnostic characters. The species can be separated from other species of the genus Demicryptochironomus (Irmakia) by the following combinations of features: partially divided superior volsella at apex, and apically pointed gonostylus with strong concavity. Etymology. The name “ dividuus ’’, a Latin word, refers to the partly divided superior volsella at apex. Male (n=2) Total length 2.4–3, 2.7 mm. Wing length 1.85–1.87 mm. Costal length 1.78 mm. Antennal length 0.8 mm. Colouration. Thorax yellowish brown, leg colour light brown, abdomen yellow to light brown. Head. Head width 500–540 µm. Temporal setae 8–10 (IV 1, OV 6–7, Po 0–2). Clypeal setae 9–10. Frontal tubercles present, 4.6–5 µm long. Eyes bare with dorsomedial extension of 115–130 µm. Ultimate flagellomere 490 µm long; AR 1.58. Length of palpomeres (I–V) (µm): 23: 46: 92: 105: 149. CA 0.63–0.68. Thorax. Acrostichals 4, dorsocentrals 12–14, prealars 3, supraalars 1–2 and scutellars 6–8. Wing (Fig. 3A). VR 1.14. R with 17 setae, R 4+5 with 18 setae. Brachiolum with 2 setae. Squama with 4 fringed setae. FCu distinctly distal to RM. Anal lobe moderately developed. Legs. Fore tibia with 2–3 setae.

Lengths (µm) and proportions of legs shown in table 2. Hypopygium (Figs. 3B–D).Anal tergite band Y shaped.Anal point 76–80.5 µm long, 9.2–11.5 µm wide, slightly widened sub apically, apically rounded, bearing 3–4 lateral setae on each side. Transverse sternapodeme 23–30 µm long. Digitiform superior volsella 18.34–20.7 µm long, 6.9–9.2 µm wide (Fig. 3D), partially bifurcated apex bearing 2 setae. Inferior volsella absent. Gonocoxite 138 µm long. Gonostylus 156–166 µm long, widest medially, apically pointed and strongly curved in middle with strong longitudinal keel. HR 0.84–0.88; HV 2.17. Distribution (Fig. 4). West Bengal, India (present record). Remarks. The new species shows closeness with D. (I). concavus Yan, Tang et Wang, 2005 in having somewhat similar shaped gonostylus but differs in the shape of superior volsella. Small thumb–like superior volsella is possessed by the new species and D. (I). fastigatus (Townes, 1945), but superior volsella is apically bisected in the new species while it is undivided apically in the latter species.Published as part of Mukherjee, Bindarika & Hazra, Niladri, 2022, Two new species of Demicryptochironomus Lenz, 1941 from India with tentative phylogenetic relationship and a revised world key to known males (Diptera: Chironomidae), pp. 88-100 in Zootaxa 5175 (1) on pages 92-95, DOI: 10.11646/zootaxa.5175.1.4, http://zenodo.org/record/700324
