Summary, etc.	Studies on the epilachna beetle complex occuring on selected vegetable <br/>crops were carried out at the College of Horticulture, Kerala Agricultural <br/>University, Vellanikkara, Thrissur, Kerala during 1995-1997 to establish their <br/>taxonomic identities. The morphology, biology and the natural enemy association of <br/>these beetles were also studied. <br/>Based on the male and female genitalial characters, the epilachna beetles <br/>feeding on brinjal, bittergourd and cowpea were identified as Henosepilachna <br/>vigintioctopunctata (Fabricius), Henosepilachna septima (Dieke) and Afidenta <br/>misera (W eise) respectively. <br/>The salient features to distinguish between these three species are the <br/>curvature of the apex of sipho which is a part of the male genitalia and the shape of <br/>the female genital plates. The apex of sipho is curved outwards with a bluntly <br/>rounded tip in both H. vigintioctopunctata and A. misera, while it is curved inwards <br/>with a sharply pointed tip in H. septima. A semicircular notch is present on the <br/>female genital plates of H. vigintioctopunctata, while there is a slit like notch in H. <br/>septima. The notch on female genital plate is absent in A. misera. <br/> It was confirmed that the beetles are highly host specific. <br/>Henosepilachna vigintioctopunctata showed a strict host restriction to solanaceous <br/>plants, while H. septima and A. misera are restricted to a few cucurbitaceous and <br/>leguminous plants respectively. <br/> <br/> <br/>There was not much gross morphological variations between the species <br/>except for their body size, H. septima being the largest and A. misera the smallest. <br/>The different spot variants met within the species by the variations in elytral <br/>maculation was found to be a morphological character only. Though the grubs of <br/>the three species are similar in external appearance, they can be easily distinguished <br/>by the structure and sclerotisation of the scoli on body surface and the details have <br/>been discussed. The three species showed similar biological attributes with a life <br/>cycle period of 25.25, 2l. 59 and 24.76 days for H. vigintioctopunctata, H. septima <br/>and A. misera respectively at 27.6°C and 89.5 per cent relative humidity. Under <br/>. field conditions, the grubs and pupae of the three species were parasited by <br/>Pediobius foveolatus (Crawford) (Eulophidae:Hymenoptera) and the egg masses <br/>were parasitised by Tetrastichus ovu/orum Ferriere (Eulophidae:Hymenoptera). <br/><br/>
