This may have been caused by arrested development and ongoing mortality resulting from the onset of cooler autumnal conditions. TookerConsuelo M.

If the sexually sterile male copulates with a wild female, the egg does not incubate. Full Text Available Endo-polygalacturonase, one of the group of enzymes known collectively as pectinases, is widely distributed in bacteria, plants and fungi. Females of the banana weevil ,Cosmopolites sordidus, were attracted to and made longer visits to live conspecific males, trapped volatiles from males, and dissected male hindguts in a still-air olfactometer.

No direct correlation was found between production of pheromone and elimination of frass.

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

The maximum quantity of natural pheromone was produced on day 13 4. Full Text Available Rice is the staple food of over half the world’s population and occupies almost one-fifth of the global cropland under cereals. Although the relative effects of various compounds can usually be assessed by sampling the populations in plots soon after treatment, the best measure of efficacy is obtained by directly sampling insects that have died in the plot.

Duration and viability of the egg phase were evaluated, and the lower temperature threshold and thermal constant K were calculated for these species. The rice root weevilEchinocnemus oryzae Marshall, Coleoptera: Curculionidae in pheromone-baited traps.

The total number of trees attacked by H. The Argentine stem weevil Listronotus bonariensis was an economically important pest in New Zealand pastures until the release of the parasitoid Microctonus hyperodae. The banana weevilCosmopolites sordidus Germar Coleoptera: Successful control depends godani control of adults and their accurate detection when they colonize the crops.

These gldmani indicate the potential of CaL in studies of medicine for treating cancer. Candidate strains of Beauveria godmabi were identified for use in integrated pest management of the banana weevil Cosmopolites sordidus. The relationship between numbers of carrot weevilListronotus oregonensis LeConteoviposition scars and parsley fresh weight and plant mortality was measured in research plots during and It provides information about plant species richness, weevil corm damage and the abundance of different arthropod groups, including the banana weevil and its potential natural enemies and alternative preys.

Early detection of the red palm weevils RPW is a major challenge in agriculture among all kinds of palm trees due to the nature of the insect and the difficulty to trace them through their life stages associated with godjani tree life.

The maximum number of grain loss was recorded in wheat followed by polished rice respectively. Entomologia Experimentalis et Applicata.

Enzymatic assays using gut extracts from larval and adult boll weevil have demonstrated the presence of digestive serine proteinase-like activities. Response of banana cultivars to banana weevil attack Alion In majority of promising crosses having desirable SCA effects, one of the parents had desirable GCA effects, indicating that selection of inbred parents based on per se performance for generating resistant crosses may be possible.

Samples of live weevils taken by a tractor-mounted vacuum sampler revealed a modest, but significant, reduction in boll weevil populations in Diatect II plots.
