The verde plant bug, Creontiades signatus (Distant), has been present in south Texas for several years but has more recently been documented as an economic threat to cultivated cotton, (Gossypium hirsutum L. Our studies over 2 yr (2009 and 2010) and two locations (Weslaco and Corpus Christi, TX) investigated feeding-injury of the verde plant bug to a range of cotton boll age classes defined by ...

Aflatoxins are potent mycotoxins produced by fungi in Aspergillus section flavi. The toxic effect of aflatoxins on humans and other animals is well known (7); thus, many countries regulate the quantity of aflatoxins allowed in foods and feeds (17). Aspergillus flavus Link:Fr. infects many oilseed crops and is frequently, as with cottonseed, the primary cause of aflatoxin contamination (13). Whe...

tents reduces yield, while feeding scars and holes on testa reduce the quality and marketability of pea seed. The pea weevil, Bruchus pisorum (L.) (Coleoptera: Bruchidae), is In addition, weevil-damaged seed has lower germination one of the most intractable pest problems of cultivated pea, Pisum sativum L. The availability of resistant cultivars would give growers rates and is prone to structur...

Several agronomic benefits can result from fall seeding of canola (Brassica spp.), but extensive research data are lacking on the potential impact of this practice on infestations of root maggots (Delia spp.) (Diptera: Anthomyiidae), which are major pests of the crop in western Canada. Field experiments making up 13 location by year combinations were conducted in central Alberta, Canada, from 1...

The East Palaearctic seed beetle Bruchidius terrenus (Coleoptera: Chrysomelidae: Bruchinae) is recorded for the first time to the Bulgarian fauna. Larvae of the bruchid infest mature seeds of introduced mimosa Albizia julibrissin (Fabacea), an ornamental tree in many countries. The level of damage on seeds caused by bruchid larvae was examined.

ABSTRACT-This experiment was carried out as factorial based on a randomized complete block design with three replications at the research station of the Islamic Azad University-Arak Branch, Iran, in 2011 and 2012. Experimental factors consisted of three levels of salicylic acid (SA); seed priming with distilled water (hydro priming), seed priming with 0.5 mM SA, and 0.5 mM SA  seed priming 1 mM...

For life to survive outside the biosphere, it must be protected from UV light and other radiation by exterior shielding or through sufficient inherent resistance to survive without protection. We tested the plausibility of inherent resistance in plant seeds, reporting in a previous paper that Arabidopsis thaliana and tobacco (Nicotiana tabacum) seeds exposed for 558 days outside the Internation...
