Plant essential oils (EOs) and a wide range of chemicals affect insect pests in many ways, such as via stimulatory, deterrent, toxic and hormonal effects. Three different compounds ((E)-β-caryophyllene (E-β-C), D-limonene (Dlime) and trans-2-dodecenol (T-2-D)) were tested against Nilaparvata lugens, Cyrtorhinus lividipennis and Paederus fuscipes, and their behavioral response was assessed. The results showed that on average, more N. lugens nymphs were repelled by E-β-C and T-2-D than by D-lime. More C. lividipennis nymphs were attracted to T-2-D and D-lime than to E-β-C. However, P. fuscipes displayed no significant response to the three chemical compounds. The results also demonstrated that T-2-D has exerted significant repellency against N. lugens and a significant attraction for C. lividipennis, while E-β-C and D-lime have no significant effect on any tested insect. T-2-D was selected and tested in a greenhouse under semi-field conditions, where the observations confirmed the results of the laboratory experiments. From the results, it can be concluded that T-2-D at a concentration of 0.06 g/L is an effective synthetic volatile chemical compound and is the strongest repellent of N. lugens and the strongest attractant for C. lividipennis. This synthetic chemical compound can be used as a pest management tool in rice agroecosystems.

Studies on Plant Parasitic Nematodes Associated with Banana in Sindh, Pakistan
Pathan, M.A.,Talpur, Muzaffar A.,Jiskani, M.M.,Wagan, K.H. Korean Society of Applied Entomology 2004 Journal of Asia-Pacific Entomology Vol.7 No.2
A survey of banana was conducted to study the occurrence and distribution of plant parasitic nematodes. The samples of soil and banana plants showing retarded growth were collected from three fields of Nasimabad (Khisano Mori), Tando Allah Yar and Mirpurkhas. The nematodes isolated from the roots and soil samples showed the presence of seven genera of plant parasitic nematodes, Hoplolaimus columbus, Belonolaimus longicaudatus, Helicotylenchus dihystera, Meloidogyne incognita, Xiphinema brevicol/e, Longidorus africanus and Trichodorus christiei. The maximum population densities (M. P. D %) and maximum frequency occurrence (M. F. 0 %) and prominence values (P. V %) were calculated for each nematode genus. The M. P. D %, M. F. 0 % and P. V % of H columbus (lance nematode), B. longicaudatus (sting nematode), M incognita (root-knot nematode) and Heli. dihystera (spiral nematode) were higher than those of other nematodes. The occurrence of these nematodes in relatively high population suggests their potential role in reducing banana production.
