描述了苜蓿种子小蜂Bruchophagusroddi（Gussakovsky）的选址和产卵行为。种子发育和形态变化的种子是敏感的小孢子虫产卵期间也进行了描述。当暴露于月桂烯、乙酸己酯、（Z）-3-乙酸己烯酯、香芹烯、辛-3-酮和β-辛烯时，雌性产卵显著更多。法尼烯当雌性暴露于辛烷-3-醇，γ-时产下较少的卵。Muurolene和2-苯基乙醇。基于对针刺荚的观察，这些化合物通过荚中的物理伤口（例如，产卵伤口）可以警告雌性避开产卵区域，使得两个卵不会产在同一种子中。由于辛烷-3-醇，γ- muurolene、2-苯基乙醇和β-虽然法尼烯集中在种荚中，但这些化合物从未受损的荚中散发的较低速率也可以提供化学刺激，帮助雌性区分种荚和植物的其他部分。苜蓿中的挥发性成分，有产卵的影响，植物部位之间的浓度变化很大，没有发生只在豆荚。
Behavior of the alfalfa seed chalcid, Bruchophagus roddi (Gussakovsky), during site selection and oviposition is described. Seed development and morphological changes in seed are also described for the period that seeds are susceptible to oviposition by chalcids. Females laid significantly more eggs when exposed to myrcene, hexyl acetate, (Z)-3-hexenyl acetate, caryophyllene, octan-3-one, and .beta.-farnesene. Fewer eggs were laid when females were exposed to octan-3-ol, .gamma.-muurolene, and 2-phenylethanol. Based on observations with pin-pricked pods, a high rate of evaporation of these compounds via physical wounds in the pod (e.g., oviposition wounds) may warn females to avoid the area for oviposition so that two eggs are not laid in the same seed. Since octan-3-ol, .gamma.-muurolene, 2-phenylethanol, and .beta.-farnesene are concentrated in seed pods, the lower rate of emanation of these compounds from undamaged pods may also provide chemical stimuli that help females distinguish seed pods from other parts of the plant. Volatile components in alfalfa that had an effect on oviposition varied substantially in concentration among plant parts; none occurred only in pods.
