the pink hibiscus mealybug maconellicoccus hirsutus (green) (hemiptera: pseudococcidae) is a serious economic pest in tropical and subtropical regions and causes damage to many agricultural, forestry and greenhouse crops. in order to identify the natural enemies of this pest, bi-weekly samplings were done in infested areas of ahvaz, located at southwest iran during 2011-2012. samples were also ...

Scymnus incisus H. Lindberg, 1931 resurrected name is a valid species, not a synonym of Nephus (Nephus) peyerimhoffi (Sicard, 1923). Nephus quadrimaculatus bucciarellii Canepari & Tedeschi, 1977 is removed from synonymy with N. (N.) ulbrichi Fürsch, 1977 and synonymized with N. (N.) schatzmayri Canepari & Tedeschi, 1977 syn. nov. Hyperaspis inexpectata Günther, 1959 resurrected name is a valid ...

the majority members of the family coccinellidae are predators, so they have received considerable research attention because of their potential to act as biocontrol agents. the coccinellids complex of pistachio trees was monitored at both cultivated and wild pistachio plantations in shahr-e babak (kerman, iran) during 2009 - 2010. sampling was carried out randomly in the cultivated pistachio p...

Interrupt Timed Automata (ITA ) form a subclass of stopwatch automata where reachability and some variants timed model checking are decidable even in presence parameters. They well suited to analyze real-time operating systems. Here we extend ITA with polynomial guards updates, leading the class (PolITA ). We prove that is 2EXPTIME on PolITA, using an adaptation cylindrical algebraic decomposit...

This field study investigated the distribution of the freshwater snails of the family Ampullariidae in 18 provinces of Thailand. The introduced Pomacea canaliculata has wide distribution in the studied provinces. Pila angelica, P. ampullacea and P. pesmei still have limited distribution. Pila polita, which is absent in the south, now can be found in Phangnga, a southern province of Thailand. Mo...

BACKGROUND The temporal dynamics of insect populations in tropical environments is highly complex and poorly known. Long-term seasonality studies are scarce, and particularly so for ichneumonid wasps (Hymenoptera Ichneumonidae). This study represents an effort to elucidate aspects of seasonality and forest succession in the Brazilian Atlantic Forest. NEW INFORMATION We report on the seasonal ...

Interrupt Timed Automata (ITA) form a subclass of stopwatch automata where reachability and some variants of timed model checking are decidable even in presence of parameters. They are well suited to model and analyze real-time operating systems. Here we extend ITA with polynomial guards and updates, leading to the class of polynomial ITA (PolITA). We prove that reachability is decidable in 2EX...
