Three entomopathogenic fungi (Verticillium lecanii, Beauveria bassiana and Metarhizium anisopliae) along with two standard insecticides (acephate and chlorpyriphos) were evaluated for their effectiveness in the field of Bunny Bt (Cry IAC) cotton neem oil + detergent (Nirma) powder and detergent powder alone during 2007-08&2008-09 against two mealybugs viz., Phenococcus solenopsis and Paracoccus marginatus. The results revealed that B. bassiana, V. lecanii and M. anisopliae brought out a reduction of 39.1, 30.9 and 28.2 per cent incidence and 69.0, 59.0 and 23.1 per cent population of mealybugs respectively, while, the insecticides acephate and chlorpyriphos brought out a reduction of 93.8 and 87.1 per cent incidence and 97.8 and 95.3 per cent population, respectively. Detergent powder brought out a reduction of 51.7 per cent incidence and 82.4 per cent population, while detergent powder + neem oil brought out a reduction of 20.9 and 36.1 per cent, respectively. Observation on the activity of predators revealed that B. bassiana, V. lecanii and M. anisopliae brought out a reduction of 61.3, 51.6, and 6.5 % coccinellids and 33.7, 15.2&22.8 % spiders as against 54.8 and 42.4 % respectively in the standard insecticide acephate. Treatments with neem oil+ detergent powder and detergent powder alone did not reduce coccinellid population, however, reduced spider population by 22.6&13.0 percent respectively. All the treatments recorded significantly higher yield over control during 2008 - 09 and the increase in yield over control ranged from 18.0 to 43.0 %.Keywords

A study was conducted to investigate the basis and mode of infection of the entomopathogenic green muscardine fungus, Metarhizium anisopliae on the mealybug, Paracoccus marginatus. The pathogenesis of M. anisopliae on P. marginatus was studied at 24, 48, 72, 96, 120, 144 and 168 hours after inoculation. The conidial adhesion and germination process of M. anisopliae occurred within 24 hours after inoculation. The hyphae penetrated the epicuticle and reached the endocuticle within 48 to 72 hours after inoculation. Lysis of the endocuticle occurred while the penetrant hyphae invaded into the epidermis. Invasion and colonization of hyphal bodies into the haemocoel of P. marginatus was observed at 72 to 120 hours after inoculation. By 120 to 144 hours after inoculation, there was considerable abundance of hyphae that extensively colonized on the host and complete invasion occurred at 168 hours after inoculation. At this stage, the larvae became moribund and died. Hyphae re-emerged out of the cuticle after 168 hours after inoculation, and grew all over the surface forming a green mycelial mat. The developmental cycle of M. anisopliae on P. marginatus took 172 to 196 hours to disintegrate and kill the insect from the day of inoculation.Keywords

The status and spread of notoriously destructive and invasive pest, Thrips parvispinus (Karny) (Thysanoptera: Terebrantia: Thripidae) on agriculturally important crops after its first report from India is reported. Description of the species and illustrations of its diagnostic characters are provided to facilitate identification. Since 2015, this species has been collected from nine host plants belonging to seven families from five Indian states, viz. Andhra Pradesh, Chhattisgarh, Karnataka, Kerala and Tamil Nadu. The establishment of this thrips species warrants special attention in India as it is a potentially damaging plant pest and has a wide host range across various plant families. Unless successful quarantine measures are put in place, the spread and subsequent depredations of cultivated crops is inevitable.Keywords

The aim of the present study was to evaluate the efficiency of artificial establishment of Beauveria bassiana as endophyte in cotton plant using different inoculation methods, and aimed to determine the effect of colonisation in cotton plant on key insect pests of cotton. Eight strains of B. bassiana isolated as endophytes were used in this experiment. The strains B. bassiana isolated as endophytes were concentrated at 1×108 conidia ml ?1 and bioassays were conducted under laboratory conditions on Aphis gossypii, Spodoptera litura and Pectinophora gossypiella. These endophytic strains demonstrated high virulence against above mentioned insects. Different inoculation methods were used to establish B. bassiana as endophyte in cotton plants. Endophytic colonisation of B. bassiana was successful in cotton plant. Beauveria bassiana colonised plant infested with insect was monitored at different time intervals. Survival of the insect was affected considerably in the B. bassiana inoculated plant. The current study clearly indicated that strains of B. bassiana isolated as endophytes caused the mortality of A. gosypii, S. litura and P. gossypiella as an entomopathogen and also as an endophyte.Keywords

The present study evaluated the relative susceptibility of insecticides viz., imidacloprid, thiamethoxam, thiacloprid, flonicamid, clothianidin, diafenthiuron, spiromesifen, thiodicarb and chlorpyriphos against field collected population of Amrasca (S.) biguttula. Out of nine insecticides, maximum susceptibility was observed with thiamethoxam. The descending order of susceptibility was observed as thiamethoxam> thiacloprid> diafenthiuron> spiromesifen> imidacloprid> clothianidin> flonicamid> thiodicarb> chlorpyriphos. Based on the relative toxicity value it was observed that the insecticides such as chlorpyriphos, thiodicarb, flonicamid and clothianidin were 14.04, 12.01, 9.43 and 9.41x, respectively less toxic as compared to thiamethoxam. The detoxification enzyme assay revealed that the activity of esterase was high in thiamethoxam and thiacloprid exposed leafhopper, while cytochrome p450 activity was high in spiromesifen, thiamethoxam and thiacloprid exposed ones. Elevated level of esterase and cytochrome p450 in the insecticide exposed leafhoppers indicates the probability of insecticide resistance development.Keywords
