Rice is the staple food of over half the world’s population and occupies almost one-fifth of the global cropland under cereals. A grandlure-and-glue reusable and insecticide-free tube GGT made with polyvinyl chloride tube, smeared with entomological glue, and lured with pheromone was tested to detect boll weevil activity across various seasons.

Full Text Available Endo-polygalacturonase, one of the group of enzymes known collectively as pectinases, is widely distributed in bacteria, plants and fungi.

Boll weevil Anthonomus grandis population genomics as a tool for monitoring and management. The main problem with the weevils come from nursery propagators who are concerned about possible effects on germination. We investigated whether these predators are attracted to such environments in response to volatiles produced by the host plant, by the weevilor by the weevil plant complex.

In the first experiment. A screening method for banana weevil Cosmopolites sordidus In total, we estimate ca.

[Apion control [Phaseolus vulgaris, Apion godmani, Honduras]]. [Spanish] [1980]

Radurisation of matured, i. The neotropical diamond weevilEntimus imperialis, is marked by rows of brilliant spots on the overall black elytra. The diploid chromosome number of the cotton boll weevilAnthonomus grandis Boheman, is Curculionidae is a major pest in East Africa causing yield losses of up to 14 metric tonnes per hectare annually. Results indicated that L 1 was more resistant to cowpea weevil than the other large seeded genotypes.

Hypersensitive response of beans to Apion godmani (Coleoptera: Curculionidae).

In this study, we surveyed the geographic variation in body size of an invasive agricultural pest, apkon rice water weevil Lissorhoptrus oryzophilus Kuschel Coleopte The temperature thresholds of this stage were 8. Curculionidae is an invasive insect pest of rice Oryza sativa L.


Fractionated doses of 6, rads of gamma irradiation administered to pupae of the boll weevilAnthonomus grandis Boh.

Despite opposition over concept and cost, insecticides, pheromone traps, poisoned baits, and approved farming practices were used to eradicate boll weevils from Virginia, North Carolina, South Carolina, Georgia, Florida, and Alabama by The weevils lay their eggs in flower buds and immature fruit where the larvae feed on the developing seed.

Traps at both placements indicated similar patterns of early-season weevil captures, which were consistent with those previously reported. The phenology and ecology of Hibiscus pernambucensis Arruda and its interaction and importance in maintaining populations of the boll weevilAnthonomus grandis Boheman, were studied over a period of 3 yr in the Soconusco Region of the state of Chiapas, Mexico.

Laboratory-reared sterilized male boll weevils can be as attractive to female weevils as overwintered field males.

Relationships of abscised cotton fruit to boll weevil Coleoptera: The radioactive paint had no effect on the mobility and longevity of the insects.

While two of the autosomal tetrads were typically ring-shaped in primary spermatocytes, the remaining 19 autosomal tetrads were rod-shaped.

The most effective dosages ranged from 0,5 to 0,85 kGy. Curculionidae at different ages. Successful control depends on control of adults and their accurate detection when they colonize the crops. It was noticed that the rate of reproduction of the rice weevils was greatly influenced by insect crowding, science adults of S. Bioassays suggested that SKTI could be used as a tool in engineering crop apkon, which might exhibit increased resistance against cotton boll weevil. Male weevils only produced pheromone on F.

The food source and field conditions during early adult development were decisive factor for the induction of reproductive dormancy. In these cultivars most of the insects are in die adult beetle stage at harvesting.

Collection of pheromone from atmosphere surrounding boll weevils ,Anthonomus grandis. Vine weevilalso known as black vine weevilOtiorhynchus sulcatus is an economically important pest affecting soft fruit and nursery stock in temperate regions. Fallen squares are a source of next generation adult boll weevils that Laboratory and field evaluation of sterile male boll weevil competitiveness. Colonizers belonging to apionn clade of foliage dwellers greatly diversified, whereas species inhabiting leaf-litter have been less successful.


Use of sterile male technique for insects to eradicate red palm weevil. They were maize cultivars namely Arun-2, Manakamana-4, Deuti, buckwheat local cultivar, wheat cultivar namely Annapurna-1, polished rice-Radha 4 and unshelled rice cultivar Mansuli under storage condition at Institute of Agriculture and Godmanj Science, Rampur, Chitwan, Nepal from June to February Sterilization of boll weevil pupae with fractionated doses of gamma irradiation.

Eastern white pine is one of the most important sawtimber species in the Northeast.

It does, however, raise important questions for future analysis in terms of the interaction between parasitism and unrealised fecundity. Thus, the potential for an effective 2-wk life span in the field suggested by the caged study did not appear to apply to laboratory-reared weevils released into cotton fields. This procedure lends itself to the large-scale sterilization of weevils needed in an eradication program.

A decrease in the population of rice weevils was noted when the irradiated males were introduced to mate with the non-irradiated females.

Hypersensitive response of beans to Apion godmani (Coleoptera: Curculionidae).

The enzyme has also been found in several weevil species and a few other insects, such as aphids, but not in Drosophila melanogaster, Anopheles gambiae, or Caenorhabditis elegans or, as far as is known, in any more primitive animal species. Full Text Available Food preference by the maize weevil gomani, Sitophilus zeamais Motschulsky was studied on seven different crops and varieties including maize, wheat and rice.

Reducing boll weevil populations by clipping terminal buds and removing abscised fruiting bodies. A key objective of monitoring in these programs is the timely detection of incipient weevil populations to limit or prevent re-infestation. A universal internal transcribed spacer primer pair included in the cocktail cross-amplifies DNA from all species, serving as a positive control.
