“…We observed from our results that the maximum use of urea fertilizer results the greenish crop and increase plant growth, crop attract insect pest which are the reasons of losses grain quantity and quality. The similar results of fertilizer effects on pest population was described by Sohail et al (2007).The present study show that aphid populations appeared after the germinations and infested the crop till the harvest, aphid populations were significantly increased with increase of plant vegetative growth, similar study defined by Bindra and Mahal (1981) Predator's population shows significant correlation with aphid, the beetle observed with low numbers during first week and increased with increases the number of aphids per plant and both adult and nymph control the pest population. Same study for natural enemies were observed by Dhaunroo et al (2018) maximum application of urea fertilizer to a crop plant can attract insect pest, and increase insect infestation.…”

Hordeum vulgare is one of the most important cereal crop plants and severe attacked by aphid. Present study was designed to evaluate the effect of different fertilizers and their combination on aphid infestation in barley. Three different fertilizer i. e. urea, DAP, and urea+DAP were applied to three different barley fields after 25 days of germinations. Data was recorded after every 10 days. Results showed that lowest pest population was recorded in urea+DAP field.

“…Abundances of jassid were negatively correlated with the numbers of abaxial and adaxial leaf trichomes, and the numbers of spines on the stems and leaves of the germplasm. Bindra and Mahal (1981) reported that high density of hair on midrib was responsible to give resistance to brinjal against jassid. The presence of trichomes on leaf hinders free movement, ease of feeding, and oviposition of insects and thus affects the growth and development of them (Amin et al, 2011).…”

The tropical vegetable, brinjal is cultivated throughout the year in Bangladesh but the crop is infested by a number of insects including jassid. This study investigated the effects of different biophysical and biochemical characteristics of twelve brinjal germplasms on the abundance and infestation of jassid. The experiment was conducted during September 2018 to March 2019 in Gazipur, Bangladesh with twelve brinjal germplasms namely BD-7320, BD-7328, BD-9952, BD-10154, BD-10158, BARI Begun-1, BARI Begun-4, BARI Begun-5, BARI Begun- 6, BARI Begun-7, BARI Begun-8 and BARI Begun-9. The incidence of jassid was recorded from 3rd December to 26th March, and the lowest population was found on BARI Begun- 6. Among the biophysical traits, plant height, number of branch and leaf per plant, and leaf area exerted significant positive correlation; whereas trichome on lower and upper surfaces of leaf, spine per stem and leaf showed significant negative correlation with the abundance of jassid. On the other hand, moisture, reducing sugar, total sugar and protein content of the leaves and fruits, chlorophyll content of the leaves exerts significant positive correlation but ash and pH contents of the leaves and fruits were negatively correlated with the abundance of jassid. Jassids showed the lowest level of leaf infestation on BARI Begun-6, which could be for further analysis to develop jassid resistant brinjal. SAARC J. Agric., 19(1): 81-91 (2021)

“…Among sucking insects, Jassid (Amarasca biguttula biguttula) is one of the major insect pest feeding on okra crop and remains active throughout the year excluding winter season (Mandal et al, 2006). It destroys the crop by sucking the cell sap mostly on lower surface of okra leaves of the plants and causes to hopper burn and 50% yield loss (Bindra and Mahal, 1979;Bindra and Mahal, 1981) and also causes 49.8% and 45.1% reduction of plant height and number of leaves respectively, due to the attack of jassid (Dandapani et al, 2003). Control strategies for jassid are extensively dependent on the use of synthetic chemical insecticides.…”

ABSTRACT:Field experiments were carried out for two seasons in 2012 to evaluate the efficacy of a new formulation of buprofezin (buprofezin 70 DF) against jassid (Amarasca biguttula biguttula Ishida) in okra, Abelmoschus esculentus (L.) Moench. The insecticide was applied at 200 and 150 g a.i./ha at the ETL level of the insect (2 Jassids/leaf) and the performance of the same was compared with imidacloprid 17.8 SL @ 20 g a.i./ha, acephate 75 SP @ 562.5g a.i./ha and an untreated control. Results revealed that both the dosages of buprofezin 70 DF were significantly superior over the untreated control at 5 % level of significance. Buprofezin 70 DF at 200 and 150 g a.i./ ha performed better over the other treatments with 88.81 and 85.96 % reduction during first season and 89.60 and 84.73% reduction during second season, respectively. Buprofezin , an insect growth regulator which had less or no hazardous effects on human health and environment and thus it can be incorporated in Integrated Pest Management programme in okra cultivation.
