Formicidae of the Andaman and Nicobar Islands (Indian Ocean: Bay of Bengal)

Ants on the Andaman and Nicobar Islands, India were surveyed. These collections doubled the number of ant species recorded from these islands (from 59 to 125). Records include five endemic species, but no endemic genera. The surveys were fairly superficial, and it is likely many species remain to be discovered on these islands

New records of insect and mite pests of spice crops in Andaman Islands, India

Molecular and biological characteristics of some geographic isolates of nucleopolyhedrovirus of Helicoverpa armigera (Lep.: Noctuidae)

Seven geographic isolates of Helicoverpa armigera NPV were characterized by PCR-RFLP techniques and their comparative virulence to second instar larvae of H. armigera (Hübner) were compared before and after exposure to simulated sunlight as well as open weather conditions on cotton and tomato plants. The PCR products of 25K FP region showed no difference among the isolates (780 bp). The PCR amplification products revealed genetic diversity among the 7 HearNPV isolates when they were digested individually using four different restriction enzymes (HindIII, BamHI, PstI, and EcoRI). The bioassays of the HearNPV isolates against the second instar larvae of H. armigera, before and after exposure to simulated sunlight, revealed a range of variation in their biological activity. However, the NGM isolate was the most virulent with the lowest LC50 and LT50 values. The dose-inhibitory response of the second instar larvae of H. armigera to the virus isolates revealed NGM isolate to be the least susceptible to simulated sunlight, having the highest ID50 value (462.9 W/m2). Experiments on persistence of HearNPV isolates on cotton and tomato plants under open weather conditions showed that the persistence of the viral isolates was relatively higher on tomato than on cotton

The hitherto unknown male of this genus is also described and imaged for the first time. Pardoteleia prater, the type species is redescribed and imaged with intraspecific variations in the Indian specimens.Not Availabl

A new genus, Anikera Hayat, gen. nov., (Type species Anikera andamana Hayat, sp. nov.), based on one female (holotype) from ANI and one female from Kerala State, and a new species of Trechnites Thomson (T. hairah Hayat, sp. nov.) are described. The latter species was described from the holotype and two paratypes collected in Kerala State, and a paratype from ANINot Availabl
