The lac insects belong to the genus Kerria (Hemiptera: Coccoidea: Kerriidae) and are commercially exploited worldwide for the production of lac, which comes from their waxy test and has diverse industrial applications. The insects are maintained by the Indian Institute of Natural Resins and Gums as distinctive lines that are cultivated and commercialized in the lac producing areas of India. The lines are all considered to belong to the genus Kerria but without validation of their taxonomic characters, and their identity to species has not been ascertained. This study used single-factor analysis of variance and several multivariate analyses, such as principal component analysis, discriminant function analysis, and canonical discriminant analysis to explore the morphometrics of some of the adult female lac insect lines. The results have enabled the identification of some taxonomically significant characters in adult females, which has grouped the 32 lac insect lines studied into 15 species along with validation of the most significant characters. Distinctive grouping patterns for the species of Kerria have been brought out using morphometrics.

The Indian lac insect, Kerria lacca (Kerr) family Lacciferidae (Kerriidae) and order Hemiptera is economically important insect exploited commercially for lac, a resin refined into shellac and other products. Natural scarlet dye obtained after purification is used as colouring agent. Its natural infestation was observed for the first time on Prosopis cineraria (L.) Druce in natural environment of Uttar Pradesh in Civil Lines (Lat.: 25.45678704, Long.: 81.83745539), Prayagraj. Natural infestation has also been observed on Calliandra surinamensis Benth. at Lajpat Rai Road (Lat.: 25.45678704, Long.: 81.83745539)and Ficus carica L. at Thornhill Road (Lat.: 25.45875352, Long.: 81.83767319) in the Prayagraj division of eastern Uttar Pradesh. Prosopis cineraria and Calliandra surinamensis is considered as plant having less commercial value but occurrence of lac on this plant in eastern Uttar Pradesh can be boon and a hope for economy of the region in near future and its commercial use is viable subsidiary occupation to agriculture. During study fairly good density of insect has been witnessed in Prayagraj district of eastern Uttar Pradesh indicative of better survivability of insect in the region for commercial exploitation.

Within the scope of a survey for natural antagonists of the invasive lobate lac scale, Kondo & Gullan , several chalcidoid parasitoids were collected in their native regions. Th scale invaded from Asia into Florida, the Bahamas and was recently detected in Cuba (Schroer et al., 2008a). In Florida it threatens a great number of native plants and cultivated fruit trees (Pemberton, 2003). Chalcidoids were collected from species of southern Indian states of Karnataka and Tamil Nadu and from and species of Thailand, Malaysia, Singapore and Indonesia. Results on collection made from India during 2005-06 were recently published by Hayat (2007) and Schroer et al. (2008b). The encyrtids and aphelinids collected in 2007 from Thailand, Malaysia and Indonesia were passed on to the first author for species identification. The collected from Indonesia and Malaysia are described herein as a new species. The terminology follows Hayat (1998).

Ladybird beetles belong to family Coccinellidae of the order Coleoptera and are important group of beetles, they are voracious predators and occupies important place in biological control. In this paper three species of the genus Coccinella belong to the subfamily Coccinellinae have been collected and rediscribed as no taxonomic work has been done on this group in Kashmir. This paper provides a detailed taxonomy of Coccinella septumpunctata, Coccinella undecimpunctata and Coccinella transversalis. Detailed description of adults and male genitalia are provided for both species along with color plates. In addition to this a dichotomous key of all species of Coccinella has been provided.
The taxonomy of the genus Chrysomphalus Ashmead (Diaspididae: Aspidiotinae) is reviewed. A new monotypic genus of armored scale, Pentalaminaspis Smith-Pardo, Evans and Dooley, is described and illustrated with Chrysomphalus minutus Kotinsky, 1908 as the type species. A new species, Chrysomphalus nepenthivorus Smith-Pardo, Evans & Dooley, is described and illustrated. This species was intercepted at a U.S. port of entry on hybrids of pitcher plants (Nepenthes) originating from Thailand. Chrysomphalus greeni Leonardi, 1914 is transferred to the genus Melanaspis and Chrysomphalus degeneratus Leonardi, 1896 is transferred to the genus Diaspidiotus. A discussion and key to species of the genus Chrysomphalus are provided as well as a key to aspidiotine genera similar to Chrysomphalus.
