Leading up to the National Moth Week on July 22, we interview some contributors of moth observations.Listen to the first podcast episode with Nagesh O. S. on the IBP blog.

    Fauna found along Satara-Gondawale road 2014-15
    Type
    Report
    Description
    I was not expecting much on this road going through a rain-shadow area of Satara Dist. During rainy season, I found bees on seasonal herbs, during winter I found migratory and resident birds, during spring I found bees on the trees in full bloom. I do not know scientific names of many species of bugs, ants, bees, lizard... Please check and suggest the names. Thanks for visiting.
  • Title
    Pollination biology of Eriolaena hookeriana Wight and Arn. (Sterculiaceae), a rare tree species of Eastern Ghats, India
    Type
    Journal Article
    Description
    Eriolaena hookeriana is a rare medium-sized deciduous tree species. The flowering is very brief and occurs during early wet season. The flowers attract certain bees such as Apis dorsata, Halictus sp., Anthophora sp., Xylocopa latipes, and also the wasp, Rhynchium sp. at the study sites. These foragers collect both pollen and nectar during which they contact the stamens and stigma and effect self- or cross-pollination. Nectar depletion by thrips during bud and flower phase and the production of few flowers daily at tree level drive the pollinator insects to visit conspecific plants to gather more forage and in this process they maximize cross-pollination. The hermaphroditic flowers with the stigmatose style beyond the height of stamens and the sticky pollen grains do not facilitate autogamy but promote out-crossing. The study showed that pollinator limitation is responsible for the low fruit set but it is, however, partly compensated by multi-seeded fruits. Bud and anther predation by beetles also affects reproductive success. Explosive fruit dehiscence and anemochory are special characteristics; these events occur during the dry season. The plant is used for various purposes locally and hence the surviving individuals are threatened. The study suggests that the rocky and nutrient-poor soils, the pollinator limitation, bud and anther predation, establishment problems and local uses collectively contribute to the rare occurrence of E. hookeriana in the Eastern Ghats.

    Interactions between insect pollinators and the ornamental tree, Tecoma stans (L.)
    Type
    Journal Article
    Description
    Tecoma stans (Bignoniaceae) is a native of Central America but occurs throughout tropical latitudes due to cultivation as an ornamental; in India it is also normally cultivated as an ornamental tree. The plant has two anthesis schedules in a day - one during 0500-0800hrs and another during 1500-1700hrs. Different species of bees and wasps collect pollen and nectar from the flowers during daylight hours, while hawk moths collect nectar during the 0530-0700hrs and 1630-1830hrs periods. The flowers are an important source of pollen and/or nectar for these insects, and all facilitate pollination. The nectar contains three common sugars: hexoses, glucose and fructose, and it is also a source of three essential amino acids: lysine, histidine and threonine, and eight non-essential amino acids: glycine, serine, proline, arginine, glutamic acid, cystine, cysteine and alanine. With these floral rewards, T. stans sustains pollinator populations in areas where it is cultivated.
