yield and quality. Applying combinations of agrichemicals is an efficient practice with known benefits. Producers may reduce the cost of pest management by limiting trips across the field. Fewer passes across a field is not only more convenient, it also reduces vine damage and has the potential to increase control of particular pests and broaden the spectrum of pests controlled. But tank mixing...

Psocids are important stored product pests found worldwide that can be spread through grain trade. Most stored-product psocids, including eggs, nymphs, and adults, are very small (~1 mm) and difficult to identify morphologically. Here, we collected 10 economically important stored-product Liposcelis spp. psocids (L. bostrychophila, L. entomophila, L. decolor, L. paeta, L. brunnea, L. corrodens,...

Information concerning vertebrate pests of beekeeping was gathered from state and provincial apiary inspectors through a questionnaire. Forty-eight states and 9 provinces responded. Additional pest information has been assembled from published articles. Bears represent the major vertebrate pest based on severity of damage to colonies. Total estimated losses reported amounted to $623,000 annuall...

The paper investigates the interaction between dynamic forms of incentive mechanisms (patent systems) and dynamic forms of problems (adaptations of pests and pathogens). Since biological problems recur, the design of the incentive mechanism must take into consideration: a) the need for investments into R&D that take into account the impermanence of the solution concepts; and b) the impact of th...

The greenkeeper is fortunate in that he is not unduly required to pinch pennies when it comes to selecting and using effective control measures. Furthermore, he is fortunate in having available reasonably satisfactory control measures for most of the insect and rodent pests that are likely to infest or seriously damage turf grasses. Unfortunately, however, prophylactic or preventive measures ar...

Genetically modified (GM) crops are used extensively worldwide to control diploid agricultural insect pests that reproduce sexually. However, future GM crops will likely soon target haplodiploid and parthenogenetic insects. As rapid pest adaptation could compromise these novel crops, strategies to manage resistance in haplodiploid and parthenogenetic pests are urgently needed. Here, we develope...

BACKGROUND Agriculture is a major contributor to the Gross Domestic Product (GDP) of Cameroon, The South West region of Cameroon is known for its potential in the production of major agricultural commodities, but farmers' yields from various speculations are low, dwindling over time due to some major constraints. Maize production is hampered by adverse socio-economic factors, several pests and ...
