A laboratory experiment was conducted to study the effect of Corcyra eggs obtained from different rearing media on the development of Chrysoperla zastrowi arabica (Henry). The results revealed that the treatment differences regarding feeding potential are non-significant indicating equal preference by the predatory grub to various eggs. The larval period and larval weight of all the three instar grubs were in the range of 1.9 to 3.3 days and 1.65 to 8.17 mg, respectively in all the treatments. The maximum weight of pupa of Chrysoperla was observed in T 6 (7.39 mg) and minimum in T 4 (5.97 mg). Regarding the period of pupal stage, the treatment differences were non significant. Regarding per cent adult emergence, the statistical differences among all treatments were non significant. The maximum number of females were observed in T 1 (1:1.53) and minimum in T 4 (1:0.87). The maximum and minimum weights of both female and male were observed in T 3 (3.87 mg and 3.51 mg) and T 8 (3.68 and 3.38 mg). Longevity of female was in the range of 6.40 to 7.73 and male was 4.87 to 5.83 days, in different treatments.

The Sapota Seed borer, Trimalitis margarias Meyrick is the new pest of sapota observed in Thane district of Maharashtra in the year 1999. Being an internal borer the pest was found difficult to control. In the present investigation efforts were made to control the pest by means of integrated pest managment at Agriculture Research Station, Palghar, Dist. Thane, Maharashtra state during 2001 to 2006 under the ICAR sponsored scheme "Study of sapota seed borer in Thane district'. The peak infestation of the pest was reported in the month of December (16.07%) followed by November (15.71%). Comparatively less infestation was reported in young sapota orchards as compared to old dense orchards. The maximum moth catch was observed during 41st and 42nd meteorological week i.e. in the month of October. Among the insecticides tested, Emamectin benzoate 5 SG was found most effective.

Investigations were carried out, for three consecutive years (2006-08), with an objective to test the efficacy of 1-methyl cyclopropene (1-MCP) in arresting the ripening and prolonging the storage and shelf life of 'Alphonso' mango fruit to suit export by sea transportation from India. After harvesting at physiological maturity, followed by pre-cooling at 13°C, fruit were exposed to vapors of 1-MCP at 70 mg/m3 (1000 ppb) for 18 hrs in air tight (plastic) treatment chamber. The treated and untreated fruits were then transferred to walk-in cooler for storage at 13±1°C, for different intervals (14, 21, and 28 days), followed by ripening at ambient temperature. Effect of 1-MCP on ripening pattern of fruits examined at six difference stages (viz. unripe, turning pale green, 1/4 ripe, 1/2 ripe, full ripe and decaying) indicated that 1- MCP treatment significantly arrested the ripening by 8 days and prolonged the subsequent stages by 9, 10, 12, 12 and 13 days, respectively, over untreated control fruit. The fruit quality assessed at different intervals viz. after 14, 21 and 28 days of storage and shelf life behavior at two stages (0 and 5 days) after storage in terms of TSS, Acidity, total sugar, reducing sugar and an organoleptic ratings, were found to improve by 1-MCP treatment with 21 days storage plus 5 days shelf life (17.93°B, 0.31%, 14.15%, 4.3%, 6.78) and 28 days storage with zero days shelf life (17.24°B, 0.29%, 14.53, 4.63%, 6.45) over control (16.93°B, 0.38%, 14.02, 4.04%, 6.33) with significant reduction in occurrence of spongy tissue (physiological disorder) from 25.07% in control to 9.45 to 12.34 % in both these 1-MCP treatments, respectively. © ISHS 2013.

The influence of nutrients and different chemicals (KNO3 - 3%, NH4(NO3)2 - 2%, Thiourea - 0.5%, Urea - 2%, GA3 - 50 ppm, Hydrogen cyanamide - 2%, Ethrel - 3000 ppm) and cultural treatments (light pruning, irrigation) applied at post harvest stage on old and new shoots, was investigated on 34 years old mango during 2008-09 in randomized block design with three replications with the aim to induce post harvest early vegetative growth, followed by flowering. All the treatments significantly influenced the duration and percentage of post harvest vegetative growth and flowering along with yield. Among the treatments, Potassium nitrate (3%) showed significant effect on early induction and higher percentage of vegetative growth in both the types of shoots (Old: 87.67% and New: 55.67%) over control (65% and 40.33%) followed by 2% ammonium nitrate (76.67%) and 2% urea (77%). Both the sources of nitrogen i.e., thiourea (0.5%) and potassium nitrate (3%) resulted in significantly higher flowering percentage (77.17% and 67.5%) over rest of the treatments, whereas KNO3 induced early flowering by 19.87 days, over control. Similarly, KNO3 (3%) retained significantly higher number of fruits per panicle (4.20), followed by light pruning (4.13) over control. GA3 and foliar spray of urea resulted significant increase in chlorophyll content up to flowering and gradually decreased with advancement of flowering. The C:N ratio estimated at four stages revealed that old shoots (12.95, 12.72, 9.60, 8.75) significantly recorded higher C:N ratio over group of new shoots (12.69, 12.30, 9.58, 11.74) except at the fruit bud stage. © ISHS 2013.

A collaborative research project was conducted during the 2007-08 and 2008- 09 mango season with an objective to develop a non-destructive method to identify and sort spongy tissue affected 'Alphonso' mango fruits using a soft X-ray imaging system, designed and developed by CEERI, Chennai, in collaboration with Dr. B.S. Konkan Krishi Vidyapeeth, Dapoli. A batch of 'Alphonso' mango fruits having different ripening stages as a treatments viz., T1 - 2 days after harvest, T2 - 3 days after harvest, T3 - 4 days after harvest, T4 - 5 days after harvest were exposed repeatedly to the X-ray imaging machine, calibrated by computing different algorithms, using base line data regarding physico-chemical properties of spongy tissue and healthy pulp of 'Alphonso' mango fruit. The machine could best detect and sort spongy tissue affected fruits from treatment (T3), followed by T 4 and T2, but was less successful for T1. The machine could also detect fruit with air pockets. © ISHS 2013.
