Studies on population dynamics of pink bollworm Pectinophora gossypiella (Saunders) in interspecific Bt and non-Bt cotton hybrids was carried out at Agricultural Research Station, Dharwad farm.
Biological Parameters of Pink Bollworm pectinophora gossypiella (Saunders) (Lepidoptera:Gelechiidae): A looming Threat for Cotton and its Eradication Opportunity International Journal of Research in Agriculture and Forestry V4 I7 2017 27 about 12-20 mm across the wings.
The pink bollworm Pectinophora gossypiella (Saunders) is a major pest of cotton Gossypium spp. in the growing areas of the south-western USA and in many other cotton-producing areas of the world. High chemical control costs, excessive economic losses, secondary pest problems, and environmental and social considerations have suggested the need for ecologically oriented pink bollworm management.
The pink bollworm had caused great losses to the farmers in the recent past, particularly in south Punjab parts of cotton cultivation, he added. Dr Zahid Mehmood said that cotton crop had been.
Trichogrammatoidea bactrae, Hymenoptera: Trichogrammatidae (about 72,000 adults) were released in long staple, Upland 1517-88 cotton (Gossypium hirsutum L.).Total parasitization in Pink Bollworm (Pectinophora gossypiella, Lepidoptera, Gelechiidae, PBW) eggs in two replications was 19.56 and 26.84% respectively.
Research in the USA since 1918 on the pink boll-worm (Pectinophora gossypiella) is reviewed under the following heads: biology and behaviour, host plants, means of spread, cotton crop damage, biological control, chemical control, control by plant resistance, kill at gin and oil mill and by seed treatment, cultural and other methods of control, rearing and surveys.-M.R.H.
The pink bollworm, Pectinophora gossypiella, is thought to have evolved in Australia where the only other two species of the same genus, P. endema and P. scutigera, are also found.Of these three species, only the pink bollworm, a worldwide pest of cotton, has the ability to enter diapause, an arrested state of development akin to vertebrate hibernation in which fully mature larvae are able to.

The State is staring at an unprecedented loss of cotton crop this year, as the pink bollworm pest is estimated to have affected nearly half of the total crop.
MULTAN: The Punjab Agriculture Research Board has decided taking stringent measures against whitefly to avoid crop losses.It was decided in a meeting of the PARB on whitefly and pink bollworm held.
SOME LEPIDOPTERA LIKELY TO BE CONFUSED WITH THE PINK BOLLWORM By CARL HEINRICH 1. Lepidoptera, Bureau of Entomology, United States Department of Agriculture INTRODUCTION The purpose of the present paper is to define the characters which will. is reproduced from Busck's article on the pink bollworm (In Jour. Agr. Research, vol. 9, no. 10, p.
Transgenic cotton producing Bacillus thuringiensis (Bt) toxins kill Lepidopteran pests and thus; can reduce reliance on insecticides to control boll worms. Through, biotechnology the naturally occurring Bt proteins are used to develop genetically modified (GM) insect-protected crops that help farmers to protect against insect damage and destruction. GM crops were first commercialized in the US.
He said the pink bollworm had developed resistance to Bt cotton at Krishna, Guntur, Prakasam, Kurnool, Kadapa, Anantapur and other districts. Mr Prasad said farmers would have to use pesticides to.
Biological control of pink bollworm in cotton crop March 2, 2019 March 2, 2019 Shakeel Anjum 5 Comments Biological control is a method of controlling pests such as insects, mites, weeds, pink bollworm and plant diseases using other organisms.
