Abstract

In this paper we consider the mutual exclusion problem on a multiple access channel. Mutual exclusion is one of the fundamental problems in distributed computing. In the classic version of this problem, n processes perform a concurrent program which occasionally triggers some of them to use shared resources, such as memory, communication channel, device, etc. The goal is to design a distributed algorithm to control entries and exits to/from the shared resource in such a way that in any time there is at most one process accessing it. We consider both the classic and a slightly weaker version of mutual exclusion, called ep-mutual-exclusion, where for each period of a process staying in the critical section the probability that there is some other process in the critical section is at most ep. We show that there are channel settings, where the classic mutual exclusion is not feasible even for randomized algorithms, while ep-mutual-exclusion is. In more relaxed channel settings, we prove an exponential gap between the makespan complexity of the classic mutual exclusion problem and its weaker ep-exclusion version. We also show how to guarantee fairness of mutual exclusion algorithms, i.e., that each process that wants to enter the critical section will eventually succeed.

Abstract

Spirotetramat applied as Movento 100 SC at dose rates: 0.7 and 1.0 L·ha-1 in a single treatment just after blossom resulted in a very high reduction of currant-sowthistle aphid - Hyperomyzus lactucae L. (Aphidoidea, Aphididae) on blackcurrants ‘Ojebyn’ and ‘Titania’. The results obtained with this pesticide applied at both tested dose rates: 0.7 and 1.0 L·ha-1 were comparable. The efficacy of spirotetramat at 7th day after treatment was similar or slightly poorer compared to standard insecticides, but at 21st day after treatment a higher reduction of aphids than with reference insecticides such as pirimicarb (Pirimor 500 WG at the rate 0.75 kg·ha-1), thiacloprid (Calypso 480 SC 0.15 L·ha-1) and thiamethoxam (Actara 25 WG at the rate 0.1 kg·ha-1) was recorded. With regard to environment safety and biodiversity it must be underlined that on plants treated with Movento 100 SC, high populations of Coccinellidae (both larvae and beetles), Syrphidae (larvae) and Phytoseiidae were noted.

18. Efficacy of Spirotetramat in the Control of Pear Psylla (Cacopsylla Pyri L.) on Pear Trees in Poland

Author

Jaworska, Krystyna, Olszak, Remigiusz W., Łabanowska, Barbara H., and Korzeniowski, Mirosław

Abstract

The effectiveness of spirotetramat in the control of pear psylla (Cacopsylla pyri) on pear trees was investigated in five field experiments, carried out in years 2009- 2011. One or two treatments were applied in June; the first treatment in the early stage of larvae hatching from eggs deposited by females from the summer generation, whilst the second application was carried out about two weeks later. In all the experiments, spirotetramat as Movento 100 SC applied at a dose of 2.25 l/ha effectively reduced the pest population after only a single application (total reduction of larvae after one week post-treatment 75.3-91.4%, and 83.7-97.6% at two weeks posttreatment). Movento 100 SC applied after a single application at a lower dose of 1.8 l/ha had a slightly worse effect (the total reduction of larvae at one week posttreatment was at the level of 58.4-91.3%, and two weeks after application at the level of 56-92.6%) - but in this case only a few larvae at stages L4 and L5 were found on pear shoots. The effectiveness of spirotetramat at both doses after two applications was very high.
