Determination of heteroptera species on canola plants in Hatay province of Turkey

Abstract

Canola (Brassica napus L.) is an important oil crop grown for animal feed, oil and biodiesel. Aim of this research was 
to determine Heteroptera species on canola in Hatay province of Turkey. Twenty-one (21) species belonging to 
Miridae, Pentatomidae, Lygaeidae, Rhopalidae and Scutelleridae families were identified. Distribution of a total of 
1431 adults according to the families and species was as follow: Miridae (1010), Exolygus gemallatus (472), E. 
rugulipennis (254), Adelphocoris lineolatus (246), E. pratensis (36), Acetropis carinata (1) and Calocoris nemoralis 
(1); Pentatomidae (235), Eurydema ventrale (140), Holcostethus vernalis (33), E. ornatum (26), Dolycoris baccarum 
(16), Carpocoris pudicus (10), C. purpureipennis (5), C. fuscispinus (2), Eysarcoris inconspicuus (1), E. fabricii (1) and 
Nezara viridula (1); Rhopalidae (114) Liorhyssus hyalinus (101), Rhopalus subrufus (11) and Corizus hyosciami (2); 
Lygaeidae (71) and Nysius cymoides (71); Scutelleridae (1) and Odontotarsus robustus (1). Adults of species 
belonging to Miridae (70.5%), Pentatomidae (16.4%), Rhopalidae (7.96%), Lygaeidae (4.96%) and Scutelleridae 
(0.069%) were determined in whole sampling sites and all of the canola varieties. Additionally, nymphs belonging to 
Miridae (79.7%), Pentatomidae (19.4%) and Lygaeidae (0.8%) families were identified. Miridae was the highest 
followed by Pentatomidae, Rhopalidae and Lygaeidae; Scutelleridae was the lowest in the whole sampled areas and 
all canola varieties. Exolygus gemallatus (472), E. rugulipennis (254) and A. lineolatus (246) belonging to Miridae had 
the highest population densities, especially increasing after the flower stage of canola and reaching the maximum 
levels at the pod stage.
