Biosystematic studies on Agromyzidae from India

Pure systematics of Agromyzids attracted the attention of many entomologists quite early in the century, but investigations on their biosystematics is still to gain the necessary attention and recognition from entomologists. Their life history and feeding habits being so closely interelated with the chemical nature of their host plant, investigations into their capability to select the right host plant become all the more important. It has become very essential to critically reassess their systematic position and the characters governing this sensitive interspecific relationship. Factors which require special attention in this regard are: (i) the organs and devices responsible for host recognition and host selection, (ii) correlation between the structure of these organs and the behaviour of these flies, (iii) recognition of special features in their biology and (iv) the study on the interrelationship between ecological factors and the special features in their biology.Though agromyzid infestation causes damage to varied plant parts such as root, stem, leaf and seed etc there is striking structural similarity in the organs and devices responsible for host selection. This is mainly due to the fact that in all cases it is the adult fly which is responsible for choosing the host. As very little information is available on the correlations between structural adaptations for host recognition, selection and the behaviour of Agromyzids, an attempt has been made to highlight these aspects.

Generic composition and distributional patterns of Agromyzidae from India (Diptera : Agromyzidae)

Abstract An analysis of the distributional patterns of Indian Agromyzidae is attempted. Out of the 26 genera known 19 have been recorded from India. An analysis of the distributional patterns and generic composition of the following 19 genera is given: Acromyza Fallen, Japanagromyza Sasakawa, Melanagromyza Hendel, Tropicomyia Spencer, Ophiomyia Drashnikov, Phytobia Lioy, Cerodontha Rondani, Calyfomyia Hendel Amauromyza Hendel, Liriomyza Mik, Lemurimyia Spencer, Paraphylomyza Hendel, Pseudonapomyza Hendel, Napomyza Westwood, Indonapomyza Singh & Ipe, Phtomyza Fallen, Cromatomyia Hardy and Phytagromyza Hendel.

Zur Biologie von Melanagromyza sojae (Zehnt.) (Diptera, Agromyzidae) und zu ihrem Auftreten in fünf Hü lsenfruchtarten bei Agra, Indien

AbstractStudies on the biology of Melanagromyza sojae (Zehntner) (Diptera, Agromyzidae) and its incidence of infestation on five cultivated pulse crops in and around Agra, India The incidence of infestation byMelanagromyza sojae was as high als 74.5% onGlycine max (Soya bean), 61.8% onPhaseolus mungo, 22.8% onPh. radiatus, 4.5% inVigna catiang and 1.7% onPh. calcaratus. Dates on the bionomy and the life cycle of the pest are given. The larvae of the three generations feed in tunnels within the cortical region in different levels of the stem. The secondary and tertiary infestation are always more destructive than the primary one. In majority of the cases of the tertiary infestation. Incidence of parasitism of species of Hymenopterous parasites belonging to three families are also recorded.

Descriptions of Two New Species of the Genera Phytobia Lioy and Phytagromyza Hendel (Diptera : Agromyzidae)*

AbstractPhytobia lebongi and Phytagromyza courtalamensis are being described here as new species. Notes on their biology and description of immature stages are also included.

Descriptions of two new species of Melanagromyza Hendel (Diptera : Agromyzidae) from India

Abstract Descriptions of two new species, M. labi and M. akbari, reared from their host-plants Dolichos lablab Linn, and Enicostema verticillatum (L.) (Gentianaceae) respectively are given.

A new species of Phytomyza fallen from Western Himalaya (Agromyzidae : Diptera)

While studying the Agrorayzidac collection from Northern India the authors came across a couple of very interesting specimens belonging to the genus Phytomyza and reared from the host-plant Thalictrum foliolosum DC. (Fam. Ranunculaceae). A predominently Palaearctic genus, Phytomyza is represented so far only by a single, common and widespread species, P. atricornis Meig., in India. From within the Oriental realm, Spencer (1961) records only four species belonging to this genus, one of them being undetermined.

Descriptions of Two New Species of Genus Lemurimyza Spencer (Agromyzidae : Diptera)†

AbstractLemurimyza bhutanica and Lemurimyza simlensis are described as new species. Notes on their biology and the description of the immature stages are also included.

Descriptions of two new species of Phytobia Lioy (Diptera : Agromyzidae) from the Western Ghats (Kerala : S. India)

While studying the collections made from the Western Ghats (Kerala) in October, 1968, we came across two new species of Agromyzidae belonging to the genus Phytobia Lioy subgenus Poemyza Hendel, the descriptions of which are included in this paper. Both species, Phytobia (Poemyza) kumliensis, sp. nov. and Phytobia (Poemyza) walarai, sp. nov., were reared from their host plants, two different species of grass, the former was also collected on wings.
