Natural abundance and host plant preference of the endoparasitoids O. pallipes was studied in Ojelat region. Four host plants were studied [tomatoes (Solanum lycopersicum) pepper (Capsicum annuum) eggplant (Solanum melongena) and kidney bean (Phaseolus vulgaris)] The parasitoids showed high populations in April and May that kept the populations of the serpentine leafminer L. trifolii at low densities till the end of the season on all studied host plants. O. pallipes recorded two peaks of abundance on the four studied host plants recording (19, and 24 individuals/ 50 infested leaflets) on tomatoes, (18, and 16 individuals/ 50 infested leaflets) on pepper, (26 and 20 individuals/ 50 infested leaflets) on eggplant and (32, 26 individuals/ 50 infested leaflets) on kidney bean during the season of the study. O. pallipes showed a relatively low preference towards kidney bean and eggplant compared with pepper and tomatoes.

Toxocariasis masih menjadi masalah pada pedet dan merugikan secara ekonomi. Kecamatan Panjatan Kulonprogo memiliki populasi pedet yang besar dan memiliki masalah Toxocariasis juga. Penelitian ini bertujuan menyidik prevalensi dan mengidentifikasi faktor risiko infeksi Toxocarara vitulorum pada pedet di Panjatan Kulonprogo. Enam ratus enam puluh spesimen feses diambil dari pedet-pedet di 6 desa di kecamatan Panjatan dengan teknik rambang klaster. Faktor risiko yang diamati meliputi aspek manajemen, hospes, lingkungan dan manajemen kesehatan. Diagnosis laboratorium dilakukan dengan metode pengapungan air garam Fulleborne dan sistem penghitungan telur Mc Master. Analisis data dilakukan secara univariat dan bivariat. Prevalensi infeksi Toxocara vitulorum sebesar 4, 7%. Beberapa faktor risiko yang berkaitan dengan Toxocariasis adalah asal-asal ternak (OR= 3), umur (OR= 2, 43), jenis pedet (OR= 2, 24), asal usul pedet (OR= 5, 85), sumber air minum (OR= 10) dan pedet yang dicampur dengan induk atau hewan lainnya (OR= 3, 0).
