During the Rapid Biodiversity Assessment (RBA) a total of 13 mantid specimens belonging to eight species under six families were collected. Anew species Caliris mukherjeei sp. nov. (Haaniidae: Caliridinae) and two new records of rare mantids to Kerala viz., Ceratomantis ghatei Roy & Svenson, 2007 (Hymenopodidae: Oxypilinae) and Dysaulophthalma nathani Stiewe, 2009 (Eremiaphilidae: Iridinae) are reported with description and redescription.

    查看更多>>摘要：Fourier transform infrared (FTIR) spectroscopic technique was carried out in wings of nine different Pierid butterflies to deduce the functional groups and properties of cuticular hydrocarbons which play a pivotal role in exhibiting charismatic colourpatterns, controlling body temperature, attracting potential mates and camouflaging against predators. There were three major types of hydrocarbons present in all butterfly wings including alkanes, alkenes and methyl hydrocarbons. The second predominantcompounds found in the butterfly wing region include alkyl halides, alcohols and phenols. There were no significant differences in the functional groups among the wings of butterflies. FTIR analysis of nine different Pierid butterfly wings showed many relative sizes of peaks. There were no significant differences in the chemical composition of wings but the colour differences were observed among the nine different butterflies. It was inferred that not majorly due to the differences in the cuticular hydrocarbons and may be due to the presence of different microstructures like scales, ridges and grooves.

    Design and testing of a novel cost-effective lethal ovitrap for the control of Aedes aegypti (Linnaeus 1762)

    查看更多>>摘要：An indigenous, novel, cost-effective, non-electric lethal ovitrap was designed for the dengue vector. The bacteria Bacillus cereus VCRC 641 was grown in a cost-effective culture medium of chicken feather waste. The culture supernatant was used as ovitrap attraction of the dengue vector of Aedes aegypti (Linnaeus 1762). Twenty experiments with 80 ovitraps, three experiments with 15,000 ovitraps, and three experiments with 3,000 ovitraps in the laboratory, outdoor and households respectively conducted,to assess the efficacy，showed that the ovitrap with B. cereus culture supernatant (10%) significantly attracted the gravid A. aegypti to lay eggs in all experimental traps. More importantly, the first instar larvae from the eggs on the traps had the mortality immediately. The novelty of this trap is proved to exhibit a dual function for attracting gravid mosquitoes and killing the newly emerged larvae. This is the first report asserting the dual role of a cost-effective, non-electric ovitrap to control dengue vectors. The ovitrap contains only simple components of a plastic bowl,a cylinder, and a plastic plate. The total cost of these materials per trap was Rs.15 only. The laboratory study showed that the experimental ovitrap attracted >10 times thecontrol traps (experimental: 1465.90+251.48 and control: 140.00+23.95). This is the first report about the efficacy of an indigenously designed lethal ovitrap for attracting dengue vector.

    Persistence of cyantranUiprole in sandy loam soil and effect of organic manure amendment

    查看更多>>摘要：The persistence of cyantraniliprole, a new systemic insecticide of the class anthxacitic diamide, was studied under the laboratory conditions in sandy loam soil and the soil amended with farmyard manure (0.5%), after spiking at 1,2 and 4 mug kg~(-1) levels in three different soil moisture regimes viz. air dry, field capacity level and also in saturated conditions. Degradation was comparatively faster in saturated than at field capacity and air dry condition. There was an increase in the persistence with increase in the spiking concentration. The persistence of cyantraniliprole was dependent on soil moisture condition, organic matter content and concentration of cyantraniliprole used.

    查看更多>>摘要：Study undertaken to find the structural arrangement of scales in similar coloured regions within butterfly wings of different species revealed their scale structure was architecturally different. The scales under scanning electron microscope showed difference among butterflies. Scales of Papilio polymnestor (Cramer) had high concentration of windows, Pareronica ceylanica (Felder) with beads and other species such as Talicada nyseus (Guerin Meneville), Atraphaneura aristolochiae (Fabricius), Junonia heirta (Fabricius), Neptis hordonia (Moore), Acrae violae (Fabricius) and Danus chrysippus (Linnaeus) had network and lamina. Tonality of colours showed diiferences in the arrangement of scales.

    Note on Thereuopoda longicornis (Fabricius, 1793) (Scutigeromorpha: Scutigeridae) from Kerala, India

    查看更多>>摘要：Description and variations of Thereuopoda longicornis (Fabricius, 1793) from Kerala, India, with a key to two widespread species of the genus is provided. It is the first attempt to describe a scutigeromorph centipede from Kerala, and one of very few,from India.Being a tropical country with four biodiversity hotspots, India is home to all kinds of centipedes, except the order Craterostigmomorpha (Palita, 2016). But there have been no comprehensive contributions ever made to the taxonomy of order Scutigeromorpha in India. The genus Thereuopoda Verhoeff, 1904 comprises two geographically widespread species, i.e., T. clunifera and T. longicornis, each showing significant morphological variations across regions (Wurmli, 1979). Scutigeromorphs are unique among centipedes in terms of their distinctive features such as compound eyes, multisegmented tarsi, dorsal tergal spiracles, domed head capsul e, and the mode of deposition of the spermatophore. They are the only living representatives of the subclassNotostigmomorpha. Comprehensive molecular data, along with their unique morphological characteristics have placed them as the sister group of all other centipedes (Murienne et al., 2010). Despite having a worldwide distribution, the Scutigeromorpha is the least studied and most poorly documented centipede order under the class Chilopoda, phylum Arthropoda (Negrea, 2003; Stoev and Geoffroy, 2004; Bonato et al., 2010; Bonato and Zapparoli, 2011).

    First report of Amegilla dizona Engel and Ceratina dentipes Friese (Hymenoptera: Apidae) from Kerala, India

    查看更多>>摘要：Two bees from family Apidae, Amegilla (Dizonamegilla) dizona Engel, 2009 and Ceratina (Neoceratina) dentipes Friese, 1914 are reported for the first time from Kerala along with their current geographical distribution. Apidae is one of the most diversebee families in the world with three subfamilies, Apinae, Nomadinae and Xylocopinae (Michener, 2007). According to Ascher and Pickering (2022), Apidae contains 5950 described species around the world. In Kerala, 37 species under eight genera were reported so far (Prakash et al., 2020). Apidae comprises social bees, solitary bees and also cleptoparasitic bees. Amegilla (Dizonamegilla) dizona and Ceratina (Neoceratina) dentipes are solitary bees. They belong to subfamily Apinae and Xylocopinae respectively. Both the bee species were collected from Kole wetland ecosystems of Kerala, which is globally acknowledged as Ramsar sites (Islam and Rahmani, 2008).

    查看更多>>摘要：Hypolimnas bolina (L), exhibit a stunningly bright and lustrous colour wing patches. The present study is focused on the variety of pigmented scales that cover the wings of H. bolina. A total of 128 different types of scales (white, brown, blue as well as black scales) were investigated, which includes 63 morphologically different types of scales on the dorsal part and 65 scales from ventral side. For the analysis the scales are taken from the black and violet portion of dorsal part and brown and white colored patches in ventral region. Micrometry of scales on the dorsal side showed a length range of about 86.6 to 102.4(0, and width range of 63 to 7 8.8mu. Dimension analysis of ventral region range from 86.6 to 106.3(0. in length and width of 66.8 to 86.6u. The shape and distribution of scale depends on their exact location on the wing which are responsible for boggling pattern and brilliant visual appearance.

The study conducted in selected villages of Karnal and Kaithal districts of Haryana state, India revealed four species of rodents - Rattus rattus, R. norveigicus, Bandicota indica and Suncus murinus. Dust mite Dermatophagoides farinal chigger mite L. deliense and fleas Xenopsylla astia and X. cheopis were prevalent on the rodents.
