| predation potential of chilocorus cacti (coleoptera: coccinellidae) to the prickly pear cacti pest dactylopius opuntiae (hemiptera: dactylopiidae). | functional response of the predator chilocorus cacti (linnaeus) (coleoptera: coccinellidae) on five densities of dactylopius opuntiae (cockerell) (hemiptera: dactylopiidae) female adults was assessed under laboratory conditions. the searching efficiency of c. cacti significantly decreased as prey density increased. the logistic regression for the predator had a negative and significant linear parameter indicating a type ii functional response. non-linear regression for holling predator equation ... | 2013 | 23949861 |
| genetic variability of dactylopius opuntiae (hemiptera, dactylopiidae) on forage cactus in northeast brazil. | the carmine cochineal dactylopius opuntiae is a key pest in productive fields of forage cactus in pernambuco, brazil. species identification by means of molecular markers assists in understanding the genetic profile, underpins morphological characterization, and supports the monitoring of populations in integrated management programs designed to control this pest. we evaluated the genetic variability of natural populations of d. opuntiae. genetic variability was analyzed with issr and rapd prime ... | 2013 | 24301784 |
| autonomous biological control of dactylopius opuntiae (hemiptera: dactyliiopidae) in a prickly pear plantation with ecological management. | it is broadly known that the conservation of biological diversity in agricultural ecosystems contributes to pest control. this process was studied in a prickly pear plantation (opuntia megacanthaandopuntia ficus-indica) located in central mexico. no insecticides have been used on this plantation since 2000, and local farmers believe that the presence of different species of insects limits the growth of the wild cochineal (dactylopius opuntiaecockerell), which is one of the main pests in this cro ... | 2016 | 27055467 |
