The polyphagous brown marmorated stink bug (Halyomorpha halys Stål.) is an important pest in many countries. Recently it was noticed that can feed on and cause damage to strawberries (Fragaria × ananassa Duch.). metabolic response of attacks studied. Brown bugs attacked strawberry fruit which had 18% lower total sugar content compared the control treatment. However, organic acid no significant ...

We describe 18 single copy nuclear DNA loci (10 loci cloned from a Sistrurus catenatus catenatus genomic library and eight intron-based loci amplified using conserved primers) that detect sequence variation in species from all genera (Sistrurus, Agkistrodon and Crotalus) of North American pit viper snakes. These loci (mean size in bp ± SE: 433 ± 51) show large numbers of phylogenetically inform...

Se entregan nuevos registros de Chinavia musiva que extiende su distribución en Chile a las regiones Coquimbo el norte y Metropolitana Santiago hacia sur. discuten los problemas identificación existentes entre esta especie Halyomorpha halys, se entrega una clave pictórica para diferenciar ambos taxones.

Abstract Unintentional introduction of natural enemies has increased in recent years due to a massive rise global trade and tourism. One such enemy is the Asian egg parasitoid Trissolcus japonicus , promising agent for classical biological control Halyomorpha halys. In Europe, adventive T. populations have been detected Switzerland, Italy Germany. Host specificity testing demonstrated that its ...

Reproductive parameters evaluation is considered as helpful tool for gene bank formation in ecological and economically important animals species. Gloydius halys caucasicus is venomous, viviparous pit viper of northwest of Iran. In this research, the spermatic reproductive parameters of this taxon were studied. Twenty six male snakes were collected from Takht-e-Soleiman region between September...

Agkisacutacin is a new fibrinogenlytic protein from Agkistrodon acutus venom. It consists of two heterologous subunits linked by an intersubunit disulfide bond. The cDNAs encoding the two chains of Agkisacutacin were cloned from a lambdagt11 cDNA library of the snake venom gland and sequenced, including the leader peptides (23/23 amino acid residues) and mature subunits (129/123 amino acid resi...
