Armyworm, Spodoptera litura is a destructive pest of several agricultural and horticultural crops all over the world including Pakistan. The life cycle of S. litura was checked on cage leaves under laboratory conditions during 2019. The incubation period was completed in 2-4 days with an average of 3.12 + 0.39 days. The colour of neonate larvae, second, third, fourth, fifth and sixth instar was pale green, dark green, dark blue-green, dark blackish-brown and blackish brown, respectively. The average life period of 1 st , 2 nd , 3 rd , 4 th , 5 th and 6 th larval instar was 3.34 + 0.32, 2.57 + 0.45, 3.49 + 0.45, 3.11 + 0.67, 3.33 + 0.87 and 2.98 ± 0.33 days, respectively. The prepupal and pupal periods was lasted 2-3 and 6-11 days, respectively. The female was long-lived than male. The longevity of males was 6-10 days while the female was 9-12 days. The ovipositional, pre-ovipositional and post ovipositional period was lasted 7.67 + 1.40, 1.74 + 0.51 and 1.78 + 0.45 days, respectively. The study showed that cabbage is a suitable host for pest growth and development and larvae feed vigorously to cabbage leaves.

The Jassid, Amarasca bigutulla bigutullaa is an important sucking pest of the okra crop. An experimental study was conducted during 2018 to check the comparative toxicity of nitenpyrem and neem oil against jassid under okra field conditions. The study revealed that 24 hours after treatment, nitenpyrem was found more toxic and effective with maximum reduction of jassid population (72.15%). Whereas, 120 hours after treatment with 4% neem oil, 15.05% jassid reduction was observed. The mortality rate of the jassid was increased with increasing in time after application of chemical insecticides. The study concluded that insecticide was most toxic and gives higher mortality of jassid as compared to neem oil.

“…Both nymphs and adult of jassid suck the cell sap from underside the leaves, resulting curling and yellowing of leaves. The excessive feeding by nymphs and adults can result necrosis from toxin that exerted in leaves (Ramzan et al, 2020). The infested leaves show burning and even fall down (Rahman et Abstract | Brinjal (Solanum melongena) is a very important and nutritious vegetable grown in tropical and subtropical regions of the world.…”

B rinjal (Solanum melongena) is an important vegetable that mostly grown in tropical and subtropical regions of the world (Anonymous, 2010). It is highly rich with many minerals, nutrients and vitamins (Obho et al., 2005;Matsubara et al., 2005). According to FAO (2012), brinjal is grown in an area of 9,044 ha with 88,148 tonnes production and 97,466 kg/ ha yield in Pakistan.The production of brinjal is decreasing every year due to biotic and abiotic factors in Pakistan. The various insect pests such as sucking (Bemisia tabaci, Aphis gossypii, Thrips palmi, Thrips tabaci and Amrasca biguttula biguttula) and chewing (Leucinodes orbonalis and Euzophera perticella) are the major insect pests (Murtaza et al., 2019) of different crops like brinjal in Pakistan (Mahmood et al., 2002). Among pests, jassid, Amrasca biguttula biguttula is serious and destructive pest of brinjal attack the crop till harvesting. Both nymphs and adult of jassid suck the cell sap from underside the leaves, resulting curling and yellowing of leaves. The excessive feeding by nymphs and adults can result necrosis from toxin that exerted in leaves (Ramzan et al., 2020). The infested leaves show burning and even fall down (Rahman et Abstract | Brinjal (Solanum melongena) is a very important and nutritious vegetable grown in tropical and subtropical regions of the world. Both nymphs and adults of Amrasca bigutulla bigutulla suck the cell sap from underside the leaves resulting in leaves curling and yellowing. Jassid (Amrasca bigutulla bigutulla) inject toxic materials into leaves which results necrosis. An experimental study was conducted by using randomized complete block design (RCBD) during 2018 to check the resistant brinjal varieties (Nirala, Dilnasheen and Bemisal) against jassid (A. bigutulla bigutulla). The highest population of jassid was recorded on 5 November while lowest on 2 December on all tested varieties. The population density was lowest in December on all varieties such as Nirala (1.0), Dilnasheen (2.1) and Bemisal (1.2), while maximum in November such as Nirala (3.8), Dilnasheen (6.6) and Bemisal (4.2) per leaf. Bemisal and Dilnasheen varieties had significantly higher jassid population per leaf as compared to Nirala variety on different sampling dates.
