Macrolophus pygmaeus Rambur (Hemiptera: Miridae) is a generalist predatory mirid widely used in augmentative biological control of various insect pests in greenhouse tomato production in Europe, including the invasive tomato leafminer, Tuta absoluta (Meyrick) (Lepidoptera, Gelechiidae). However, its biocontrol efficacy often relies on the presence of alternative prey. The present study aimed at...

Linguatula serrata is an arthropod of the class pentastomida, found worldwide. It has a zoonotic importance to humans either by ingestion of nymphs (nasopharyngeal linguatulosis) or by ingestion of eggs (visceral linguatulosis). This study aimed to record the prevalence rate of this zoonotic parasite in camels and goats as well as experimental infestation of dogs to collect and identify the adu...

Linguatula serrata, well known as tongue worm; is an aberrant cosmopolitan parasite, which inhabits the canine respiratory system (final host). The discharged eggs infect many plant feeder animals including human causing visceral and nasopharyngeal linguatulosis which is known as “Marrara syndrome”. In current study, the prevalence of infection with L. serrata nymphs in mesenteric lymph nodes (...

Diaphorina citri is the vector of bacterium that cause “huanglongbing” (HLB). The psyllid acquires pathogen after feeding on infected plants and transmits it to other trees as moves through orchard. psyllid’s movement directly affected by abiotic biotic factors, such presence conspecific insects natural enemies. We evaluated effects nymphs either not parasitized or Tamarixia radiata oviposition...

Hexanic extracts from leaves and fruits of Schinus molle were tested for repellent and insecticidal properties against first instar nymphs and eggs of Triatoma infestans, the vector of Chagas' disease. Leaf and fruit extracts were highly repellent for first nymphs. Fruit extracts had also ovicidal activity.

The objective of the present work was to design a rearing method for the Moroccan or Mediterranean locust Dociostaurus maroccanus and to breed it. The duration of the post-embryonic development from N1 to adult ranged between 35 and 38 days, independently of whether nymphs were reared at constant temperature or in cages with incandescent light bulbs that a€ord heat for thermo-regulation. In con...

Sibling cannibalism-the killing and consumption of conspecifics within broods-carries a high risk of direct and inclusive fitness loss for parents and offspring. We reported previously that a unique vibrational behavior shown by the mother of the subsocial burrower bug, Adomerus rotundus (Heteroptera: Cydnidae), induced synchronous hatching. Maternal regulation may be one of the most effective ...

The complete life cycle of Triatoma flavida, weekly fed on hens, was studied at 28+/-2 degrees C and 80+/-10% RH. Aspects related to hatching, life span, mortality and feeding behavior for each stage of its life cycle were evaluated. The hatching rate observed for 100 eggs was 93% with an average incubation period of 27.2 days. Sixty-two nymphs completed the cycle and the mean egg to adult deve...

For many insect species, group living provides physiological and behavioral benefits, including faster development. Bed bugs (Cimex lectularius L.) live in aggregations composed of eggs, nymphs, and adults of various ages. Our aim was to determine whether bed bug nymphs reared in groups develop faster than solitary nymphs. We reared first instars either in isolation or in groups from hatching t...
