“…Our study is the first to report a pest, predator and pollinator species inventory in a mango-based agroforestry field in Bangladesh. On the other hand, crop species sometimes may create favorable conditions for pest incidence and damage (Ram et al 1989). Plant species diversity in agroforestry influences the survival and abundance of insects by modifying the microclimate in the agro-ecosystem and could reduce pest attack; however, the natural enemies decrease (Gold et al 1989).…”

Insect species inventories along with pest prevalence, foraging behavior of pollinators and their effect on fruit set of mango were studied in a mango‐based agroforestry area in Bangladesh during January to June 2013. Of 1751 collected insects, 11 species in five orders and nine families were pests, 13 species in six orders and eight families were predators and eight species belonging to three orders and seven families were found as pollinators. The pests exerted significantly higher abundance but lower diversity than pollinator, predator and other insects. The pollinator richness was found to be lowest but showed higher as well as similar diversity to other category insects. Three pest species prevailed throughout the season and hoppers showed significant abundance. Among the predators, ants were most abundant. Sulphur butterfly and syrphid fly revealed statistically identical and higher abundance than other pollinators. During the flowering season, pests were dominant and the abundance of insects was observed to peak at 11.00 h. The pollinators differed in their landing duration on flowers and their activity led to higher levels of fruit set. This study provides baseline information on insect abundance in an agroforestry system, which stresses the importance of conservation of beneficial insects.

“…Our findings were in concurrence with Kaushik et al (2012) and Kannan and Rao (2000) who observed significant abundance of hopper on mango plants. The plant species diversity in the agroforestry may have influenced the survival and abundance of insects by modifying the microclimate (Ram et al, 1989). Ram et al (1989) reported that crop species sometimes create favorable conditions for pest incidence and damage.…”

The abundance of insect pests, predators and pollinators and status of pest insects associated with citrus, mango and pineapple crops grown in an agroforestry in Bangladesh was studied during July 2015 to June 2016. Twenty five species of insects belonging to 19 families in 5 orders were found as pest of citrus and their relative abundance varied from 2.4 to 13.4%. Among the citrus pests, green leaf hopper was most abundant, but whitefly, mealy bug, lemon butterfly and leaf minor were found as major pests. Fifteen species of insects under 13 families in 6 orders were found as pests of mango and their relative abundance varied from 0.5 to 82.6%, and hopper and fruit fly were found as major pests. Four species of insects belonging to 4 families in 3 orders were found as pest of pineapple and their relative abundance varied from 12.2 to 44.9%, and all were found as minor pests. There were 20 species of predator insects belonging to 13 families in 6 orders and their abundance ranged from 0.8 to 2.5/ 40 sweeps. In total 19 species of insects belonging to 12 families in 4 orders were found as pollinators and their abundance varied from 1.7 to 5.1/40 sweeps. The ants and honeybees were most abundant as predators and pollinators, respectively. SAARC J. Agri., 17(1): 13-22 (2019)

“…It may be due to the perennial nature of the crop, large scale monoculture, high plant density and excessive use of fertilizer, irrigation, and pesticides favoring the multiplication of this pest. It has been reported that plant species diversity in an agro-forestry influences the survival and abundance of insects by modifying the microclimate in the agro-ecosystem and could reduce pest attack, however the natural enemies decrease (Ram et al, 1989). On the contrary, crop species sometimes may create favorable conditions for pest incidence and damage (Ram et al, 1989).…”

Weekly sweeping was done by sweep net in order to collect insects to study the effect of weather parameters on the seasonal abundance of total insect species as well as mango hopper population in a mango-based agroforestry in Bangladesh during January to June 2013. The total insect species abundance was the highest during April to May, following the flushing of inflorescence and fruit set. At that time temperature and relative humidity were comparatively higher and there was rainfall. Mango hopper population was the highest in May and synchronized to fruit set. The abundance of total insect species and mango hopper population showed significant positive correlation with temperature, and relative humidity, while significant negative correlation with light intensity and non-significant positive correlation with rainfall. Multiple linear regression equation based on weather parameters revealed 59.2% and 61.7% role on population build up of total insect species and mango hopper, respectively. Temperature was found to be the most important effect which individually contributed 31.3% on population abundance of total insect species and 29.9% on mango hopper.
