Black fly immature stages control efficacy (Diptera: Simuliidae) by means of Bti preparations

2021

In the Valencian Autonomous Region, eastern Spain, for approximately 20 years, there has been a constant increase in populations of Black flies (Diptera: Simuliidae). This observation has been evidenced mainly by the medical reports from health centers and hospitals. Due to the inconvenience and damage caused by this insect to the human being, one of the municipalities most affected by the simuliids was chosen, to verify the effectiveness of Bti preparations on immature black fly states. In this article, the results of this scientific experience are presented and its high efficiency in the control of the immature populations of this harmful arthropod is corroborated.

First report of Antigastra catalaunalis on sesame in Greece.

2017

Τον Αύγουστο του 2016, καταγράφηκαν σοβαρές προσβολές σε καλλιέργειες σουσαμιού από το έντομο Antigastra catalaunalis (Duponchel) (Lepidoptera: Crambidae) σε αγροτικές περιοχές της Περιφερειακής Ενότητας Δράμας. Το A. catalaunalis είναι ένας σημαντικός εχθρός της καλλιέργειας του σουσαμιού σε περιοχές όπου αυτό καλλιεργείται. Παρατηρήθηκαν συμπτώματα προσβολής από τις προνύμφες του εντόμου σε φύλλα, βλαστούς και κάψες. Οι προσβολές καταγράφηκαν σε όλους τους αγρούς με καλλιέργεια σουσαμιού που επιθεωρήθηκαν, με επίπεδα προσβολής υψηλά τα οποία προκάλεσαν οικονομική απώλεια. Στο βαθμό που γνωρίζουμε, αυτή είναι η πρώτη αναφορά σοβαρών προσβολών σουσαμιού από το Α. catalaunalis στην Ελλάδα.

Effect of Cry Toxins on Xylotrechus arvicola (Coleoptera: Cerambycidae) Larvae

2022

Simple Summary Xylotrechus arvicola is a destructive pest in vineyards (Vitis vinifera) in the main wine-producing areas of the Iberian Peninsula. X. arvicola larvae bore into the grapevine wood-making galleries, thus damaging the plant both directly and indirectly. The susceptibility of X. arvicola larvae to five coleopteran toxic Cry proteins was evaluated under laboratory conditions in order to deepen the knowledge of the effect of these proteins on this insect throughout its biological development. The Cry proteins tested could be applied to control X. arvicola larvae since they were able to kill them and cause serious alterations in the larvae during the remaining months of development…

Current situation and historical evolution of the study and research of blackflies (Diptera: Simuliidae) in Spain. A tale of bleeding bites

2019

The black flies are nematocerous dipterans belonging to the Simuliidae family. This group of insects has become highly relevant in certain regions of the country since 1995. These insects, considered typical in natural lotic environments of clean fresh water, have colonized water channels of very different dimensions. They are currently present in most of the water courses around the country, as demonstrated in the Valencian Autonomous Region, where they can be found in headwaters, middle stretches and river mouths, as well as in irrigation systems with greater or lesser water permanence, such as irrigation reservoirs, channels and ditches. Since 2017 different regions of the country have i…
