Grasshopper Management.pmd
Grasshoppers are divided into two major subgroups: the short-horned grasshoppers (Figure 1) and the long-horned grasshoppers, Mormon crickets and katydids (Figure 2). Short-horned grasshoppers are responsible for most of the reported crop losses. As a result, individuals of this subgroup are popularly referred to as “grasshoppers.” Figure 1. A mature two-striped female grasshopper (Melanoplus b...
متن کاملGrasshopper Avoidance of Patterns
Motivated by a geometrical Thue-type problem, we introduce a new variant of the classical pattern avoidance in words, where jumping over a letter in the pattern occurrence is allowed. We say that pattern p ∈ E+ occurs with jumps in a word w = a1a2 . . . ak ∈ A+, if there exist a non-erasing morphism f from E∗ to A∗ and a sequence (i1, i2, . . . , il) satisfying ij+1 ∈ {ij + 1, ij + 2} for j = 1...
متن کاملCongeries , Mapping and Grasshopper
Conventional computer systems implement a dichotomy of storage mechanisms: a file store providing a durable repository allowing data to exist after the creating program has ceased execution (such data is termed long-term data), and virtual memory providing a repository for data during program execution (such data is termed short-term data). In typical conventional systems it is the responsibili...

متن کاملOviposition Digging in the Grasshopper
1. Transection of the ventral nerve cord of female grasshoppers activates the rhythmical motor programme for oviposition digging. 2. Electrical stimulation of the cut nerve cord had the following effects on elicited oviposition motor activity: (i) shortand long-lasting inhibition of activity, (ii) phase resetting and (iii) modulation of burst frequency. 3. Cold saline applied to the nerve cord ...
