A survey conducted from January to March 1996 to determine the distribution of the red coconut scale, Furcaspis oceanica Lindinger (Homoptera : Diaspididae) and its natural enemy, Adelencyrtus oceanicus Doutt (Hymenoptera: Encyrtidae) introduced to Guam in 1988-89, showed that both have spread to all the villages of Guam except the southern most village of Umatac. There were more male scales than females in the samples collected. Males were not parasitized by A. oceanicus. A high rate of parasitization by A. oceanicus was noted in the villages of Talofofo, Harmon and Merizo.

Chromolaena odorata (L.) R.M. King and H. Robinson is a herbaceous perennial belonging to the family Asteraceae (Compositae). It occurs naturally over a wide area of the tropical and subtropical Americas. from Southern Florida to the northern border of Argentina, and has become a serious problem in the humid tropical regions of Africa, Asia, and the Mariana Islands (Muniappan et al.,1988).Keywords

A field experiment was conducted during the 2016-17 mango cropping season in farmers’ fields of Gazipur, Rajshahi and Chapainawabgonj districts of Bangladesh to find an effective bio-rational management option for controlling the mango hopper, Idioscopus nagpurensis (Pruthi) (Hemiptera: Cicadellidae). Randomized Complete Block Design was used incorporating 8 treatments with 3 replications. The treatments were pruning of overcrowded and overlapping branches, spraying of azadirachtin, Beauveria bassiana (Lycomax, Russel IPM), imidacloprid insecticide, installation of yellow sticky grey and blue sticky trap and untreated control. Lowest leafhopper population was recorded in B. bassiana (3.0 hoppers/sweep/tree) followed by imidacloprid (3.7 leafhoppers/sweep/tree) treatments. Highest number of fruit retention was recorded in imidacloprid (40.00 fruits/20 inflorescence/tree) followed B. bassiana (32.67 fruits/20 inflorescence/tree) and azadirachtin (24.00 fruits/20 inflorescence/tree). Imidacloprid treatment offered maximum marginal benefit cost ratio (5.60). Increasing trend of hopper population was recorded in control. Considering health and environment issues, spraying of B. bassiana @ 5.0g/L of water at flower initiation stage, flowering stage and pea stage may be recommended for controlling mango hopper.Keywords

The experiment was carried out in farmers’ fields of Chaklarhat, Tunirhat, Panchagarh and Research Field of Horticulture Research Center, Bari, Gazipur from October 2017 to June 2018 to findan effective and suitable management approach against tomato leaf miner, Tuta absoluta. There was a total of ten treatments, viz., Treatment 1 = Application of Metarrhizium anisolpiae (Lycomax, Russel IPM) biopesticide in soil @ 5g/L of water, Treatment 2 = Foliar spray of azadirachtin (Bio-Neem plus 1EC @ 1ml/L of water), Treatment 3 = Foliar spray of Bacillus thuringiensis (Biocure) @ 2g/L of water, Treatment 4 = Mass trapping through installation of delta sex pheromone trap, Treatment 5 = Spraying of spinosad (Tracer 45WSC) @ 0.5ml/L of water, Treatment 6 = Spraying with chlorantraniprole (Coragen 20SC) @ 0.5ml/L of water, Treatment 7 = Hand picking and destruction of infested leaf and fruit, Treatment 8 = Foliar spray of B. thuringiensis (Biocure) @ 2g/L of water + mass trapping through installation of delta sex pheromone trap + application of M. anisolpiae biopesticide in soil @ 5g/L of water, Treatment 9 = Foliar spray of azadirachtin (Bio-Neem plus 1EC @ 1ml/L of water) + mass trapping through installation of delta sex pheromone trap + Application of M. anisopliae (Lycomax, Russel IPM) biopesticide in soil @ 5g/L of water and Treatment 10 = untreated control were evaluated against T. absoluta following RCB design with three replications. Results revealed that foliar spray of azadirachtin (Bio- Neem plus 1EC @ 1ml/L of water) + mass trapping through installation of delta sex pheromone trap + application of M. anisopliae (Lycomax, Russel IPM) biopesticide in soil @ 5g/L of water performed best in reducing T. absoluta infestation, increase of marketable yield and highest marginal benefit cost ratio.Keywords
