Since at least 2005, a possibly introduced mealybug of the genus Phenacoccus has been causing serious damage to cotton (Gossypium hirsutum) over much Sindh and Punjab districts Pakistan in north-western India. Some short papers have published locally giving details on structure biology this species suggesting name gossypiphilous Abbas, Arif & Saeed (2005) but without designating type specimens or depositories. This is here considered nomen nudum. A detailed morphological study unable...

Helicoverpa armigera H. is a polyphagous notorious pest of number economic crops including tomato. In tomato, it can reduce its yield as high 70% due to fruit boring. Although some predators and parasitoids have been recorded in the field for their natural control, manipulation successful crop management still awaited. To overcome this pest, insecticides play significant role effective program globally. Tomato an absolutely perishable commodity needs specified period required between...

Mango (Mangifera indica L.) is famous among all fruits because of its taste, variety and color. However, the quality mango mainly deteriorated by insect-pests complex. The study was performed to evaluate bagging effects on complex, yield at private orchards located in Multan district. A cultivar, Anwar Rataul selected, were bagged during 1st week May (at stone size stage) July 2017 maturity stage). results indicated that attack fruit flies other complex zero fruits. It further recorded...

Cotton (Gossypium hirsutum L.), being a cash and fiber crop is of high significance in Pakistan. Numerous insect pests viral diseases Pakistan around the world attack cotton crop. Genetically modified (transgenic, resistant to lepidopteran insects), hereafter written as 'Bt-cotton' has been introduced many regions combat bollworms. However, cultivars differ their pest susceptibility, yield response quality traits. Nonetheless, recent studies have indicated that are evolving resistance...

Fodder crops play an important role in sustainable agriculture as they provide feed for animals, which is ultimately converted to human food. Alfalfa one of the most fodder having high nutritive value livestock. However, seed production alfalfa crop seriously affected by several factors and highest reduction yield caused stink bug infestation. The current study evaluated different insecticides control bugs during 2016–17. efficacy ten insecticides, i.e., acephate, dimethoate, malathion,...

Abstract In 2004–05, during the December to February about 141 mango farmers were interviewed peak activity of mealy bug in southern Punjab, Pakistan. The objective was know farmers’ knowledge, perceptions and practices management bug. Most (94.33%) reported that Chaunsa variety (king all varieties) susceptible irrigation water major source flare up this pest. Basudin Supracide most commonly used insecticides as 72.92 51.77 percent gave positive response grease bands applied for control by...
