| host preference and development of leptoglossus zonatus (hemiptera: coreidae) on satsuma mandarin. | leptoglossus zonatus (dallas) (hemiptera: coreidae) has recently emerged as a key pest of satsuma mandarin, citrus unshiu marcovitch, and other fruit crops in the gulf coast region of the united states. studies were conducted under laboratory conditions (25 +/- 2 degrees c, 50 +/- 10% rh, and a photoperiod of 14:10 [l:d] h) to investigate host preference and suitability of satsuma fruit as host for this pest. three separate multiple choice experiments were performed to compare attraction of l. z ... | 2009 | 19886456 |
| economic injury levels and economic thresholds for leptoglossus zonatus (dallas) (hemiptera: coreidae) infesting seed maize. | although leptoglossus zonatus is considered a secondary pest of maize grown for grain, when grown for seed, this pest can cause significant economic damage. there are no records of management recommendations for this pest. the objectives of this work were to quantify losses caused by l. zonatus to different genotypes used for seed maize production and to estimate the acute toxicity of selected insecticides to l. zonatus using different application technologies. the ultimate goal was to calculate ... | 2018 | 28731614 |
| digestion in adult females of the leaf-footed bug leptoglossus zonatus (hemiptera: coreidae) with emphasis on the glycoside hydrolases α-amylase, α-galactosidase, and α-glucosidase. | the leaffooted bug, leptoglossus zonatus (hemiptera: coreidae) is an emerging pest of several crops around the world and up to now very little is known of its digestive system. in this article, glycoside hydrolase (carbohydrase) activities in the adult midgut cells and in the luminal contents of l. zonatus adult females were studied. the results showed the distribution of digestive carbohydrases in adults of this heteropteran species in the different intestinal compartments. determination of the ... | 2014 | 24481987 |
| the metathoracic scent gland of the leaf-footed bug, leptoglossus zonatus. | the metathoracic scent gland of 25-day-old adults of both sexes of the leaf-footed bug, leptoglossus zonatus (dallas) (heteroptera: coreidae), are described based on optical microscopy analysis. no sexual dimorphism was observed in the glandular composition of this species. the gland is located in the anteroventral corner of the metathoracic pleura between the middle and posterior coxal pits. the opening to the outside of the gland is very wide and permanently open as it lacks a protective membr ... | 2013 | 24773315 |
| genetic variability of two leaffooted bugs, leptoglossus clypealis and leptoglossus zonatus (hemiptera: coreidae) in the central valley of california. | leaffooted plant bugs (lfpbs) (leptoglossus spp., guérin-méneville) (hemiptera: coreidae) are large seed-feeding bugs native to the western hemisphere. in california, several leptoglossus spp. feed on almonds, pistachios, and pomegranate and are occasional pests. the objective of this study was to survey the different species of leptoglossus present in almond, pistachio, and pomegranate orchards in the central valley of california. we used two molecular markers, amplified fragment length polymor ... | 2017 | 29045641 |
